Massachusetts Criminal Charges Defense

Massachusetts criminal charges range from misdemeanor possession to felony firearms offenses with mandatory minimums to complex sexual assault prosecutions. Each charge category has its own statute, its own elements, its own evidentiary demands, and its own sentencing exposure. A defense that works in an OUI case does not apply in a firearms case. A mitigation strategy that is effective in a drug possession case is irrelevant in a sex offense prosecution. Effective criminal defense is charge-specific.

Attorney Joe Serpa has defended clients against the full range of Massachusetts criminal charges since 1995, across the District Courts, the Boston Municipal Court, and the Superior Court. Contact Serpa Law Office at 617.936.0201 for an immediate case review.

Firearms Offenses in Massachusetts

Massachusetts has among the strictest firearms laws in the country. Carrying a firearm without a license under M.G.L. c. 269, § 10(a) is punishable by a mandatory minimum of 18 months in a House of Correction and up to 5 years in state prison, with no possibility of a suspended sentence or probation on the mandatory minimum. Possession of a large capacity feeding device, a short-barreled rifle or shotgun, or a machine gun is punishable by even more severe mandatory minimums. And the October 2026 registration deadline under M.G.L. c. 140, § 121B applies to owners whose firearms were previously lawful, with a fine for a first offense and increasing penalties for later offenses.

Defense of Massachusetts firearms charges begins with the constitutionality of the stop or search that produced the weapon. If the firearm was recovered through an unconstitutional search, a Motion to Suppress is the primary defense vehicle. Secondary defenses address the elements of the specific charge: whether the defendant had knowledge of the firearm’s presence, whether the firearm was operable, and whether any licensing exception applies. For out-of-state visitors who traveled to Massachusetts with a lawfully owned firearm, the FOPA federal safe passage defense may be available under 18 U.S.C. § 926A. See also: Massachusetts Firearms Registration Deadline 2026.

Drug Crimes

Massachusetts drug charges under M.G.L. c. 94C range from simple possession, a misdemeanor for most first offenses, to trafficking in large quantities, which is punishable by mandatory minimum state prison sentences. The key distinctions in drug defense are: whether the substance was what the government alleges (requiring certified laboratory analysis), whether the defendant had knowing possession or control (constructive possession in shared spaces is heavily litigated), and whether the evidence was obtained through a lawful search. Drug charges have particularly severe consequences for non-citizens: a drug distribution conviction can constitute a federal aggravated felony triggering mandatory deportation with no discretionary relief. A continuance without a finding (CWOF) on a drug distribution charge may have the same immigration consequence as a conviction.

Sexual Assault and Rape Defense

Sexual assault and rape charges under M.G.L. c. 265, §§ 22 to 23B are serious felonies. A conviction can bring a state prison sentence and mandatory sex offender registration under M.G.L. c. 6, §§ 178C to 178P. Many of these cases end in a trial, because the defense disputes the basic facts of the allegation.

Defense of sexual assault charges requires a thorough investigation of the complaining witness’s prior statements and conduct, digital communications between the parties, DNA and forensic evidence, and the timeline of the alleged incident. A university student may face criminal charges and a campus Title IX proceeding based on the same allegations. The defense must coordinate the two proceedings, because the Commonwealth can use statements made at a campus hearing in the criminal case.

Indecent Assault and Battery

The firm’s page on indecent assault and battery explains the separate statutes, consent, the age of the alleged victim, the evidence, sentencing, and sex offender registration. The Commonwealth must prove the elements of the specific statute charged in the complaint or indictment.

Fake ID and Misuse of an RMV Document

Many charges for fake ID and misuse of an RMV document under M.G.L. c. 90, § 24B involve college and university students in the Boston and Cambridge area. These cases usually begin with a clerk-magistrate hearing, a private hearing that takes place before any complaint issues. The defense tries to resolve the case at that hearing, before any CORI entry is created.

A successful defense at the clerk-magistrate hearing leaves no public record and creates no duty to report the case to a university disciplinary body or a licensing board. See Student Fake ID FAQs and Fake ID Charges and the Clerk-Magistrate Hearing.

AI-Generated Pornography and Deepfake Criminal Charges

Massachusetts enacted criminal penalties for the non-consensual distribution of AI-generated intimate images and deepfake pornography under M.G.L. c. 272, § 53C, effective 2024. These charges arise most frequently in contexts involving students and domestic disputes, and they often intersect with parallel civil claims and campus disciplinary proceedings. Defense of AI deepfake charges requires analysis of the specific conduct alleged, the technical evidence of image generation, the defendant’s intent, and whether any consent or public interest defense is available. See also: Digital Evidence in Massachusetts Criminal Cases.

Criminal Harassment

Criminal harassment under M.G.L. c. 265, § 43A(a) punishes a pattern of conduct rather than any single illegal act. The Commonwealth must prove five elements. The defendant engaged in a knowing pattern of conduct or speech, or a series of acts, on at least three separate occasions. The defendant intended to target the complainant on each occasion. The conduct seriously alarmed the complainant. The conduct would cause a reasonable person to suffer substantial emotional distress. The defendant acted willfully and maliciously. Commonwealth v. Johnson, 470 Mass. 300, 307 (2014), quoting Commonwealth v. McDonald, 462 Mass. 236, 240 (2012). No act in the series has to be a crime on its own, so these cases depend on whether three qualifying acts exist and on whether each was directed at the complainant. Where the conduct consists of protected speech, the Commonwealth cannot meet its burden at all. Commonwealth v. Bigelow, 475 Mass. 554 (2016). The elements, the penalties, and the defenses are set out at Massachusetts criminal harassment defense.

Stalking

Stalking and criminal harassment are charged together often enough that clients assume they are the same offense. The two offenses are distinct. Stalking under M.G.L. c. 265, § 43 requires the same pattern of conduct and adds a second element: a threat made with the intent to place the person in imminent fear of death or bodily injury. Section 43 is punished far more severely, by as much as five years in state prison rather than a house of correction term. Which section is charged, and whether the threat element can be proved, usually decides the case. The two offenses are compared at Massachusetts stalking defense under M.G.L. c. 265, § 43.

Nonconsensual Intimate Images

Massachusetts had no dedicated nonconsensual intimate image statute until Chapter 118 of the Acts of 2024. That act added M.G.L. c. 265, § 43A(b), which punishes distributing visual material depicting an identifiable person who is nude, partially nude, or engaged in sexual conduct, and which defines digitization so that the subsection covers artificially generated and altered images as well. Section 43A therefore contains two unrelated offenses. Criminal harassment is subsection (a). Nonconsensual intimate images is subsection (b). The federal TAKE IT DOWN Act covers the same conduct and adds a platform takedown obligation. The elements, the exclusions, and the defenses are at revenge porn and nonconsensual intimate images.

Hidden Camera and Secret Recording Charges

M.G.L. c. 272, § 105 punishes secretly photographing or recording a person who is nude or partially nude. On a criminal complaint, the § 105 charge often appears as photographing an unsuspecting nude person. Section 105 also punishes upskirting, which means secretly photographing or recording under a person’s clothing. A person who sends the photo or video to someone else can face a separate felony charge for dissemination under § 105(c). In Commonwealth v. Goncalves, the Supreme Judicial Court held that dissemination requires sending the image to at least one third party, meaning someone other than the person shown. The firm’s page on hidden camera and secret recording charges explains the elements, the penalties, and the defenses.

Open and Gross Lewdness and Indecent Exposure

Open and gross lewdness and lascivious behavior under G.L. c. 272, § 16 is a felony. The Commonwealth must prove an intentional, open exposure of the genitals, buttocks, or female breasts that in fact shocked or alarmed at least one person. Indecent exposure under G.L. c. 272, § 53 is a misdemeanor. The Commonwealth must prove only an intentional exposure of the genitals that offended someone. A first conviction of open and gross lewdness does not require sex offender registration. The firm’s page on open and gross lewdness and indecent exposure charges explains nudity at home and in public places, the clerk-magistrate hearing, the penalties, and the defenses.

Massachusetts Drug Charges

Massachusetts drug charges under G.L. c. 94C range from simple possession to distribution, possession with intent to distribute, trafficking, and the additional offense defined by § 32J. The defense begins with the exact section charged, the statutory class or weight, the evidence of possession and intent, and the legality of the police investigation. The firm’s Massachusetts drug-crime defense page explains the principal offenses, evidence, suppression issues, diversion provisions, and consequences.

Possession With Intent to Distribute

Simple possession and possession with intent to distribute require different evidence. Possession with intent adds a specific intent to transfer the substance to another person. The Commonwealth may rely on quantity, packaging, scales, transaction records, communications, cash, observations, and expert testimony, but no single factor establishes intent in every case. The statutory class of the substance also determines whether the offense is a felony or misdemeanor and the applicable maximum penalty. See distribution, possession with intent to distribute, and trafficking in Massachusetts.

Drug Charges Near Schools, Public Parks, and Playgrounds

G.L. c. 94C, § 32J contains separate location provisions. For a qualifying school, a listed underlying violation must occur “in, on or within 300 feet of the real property comprising” the school and between 5:00 a.m. and midnight, whether or not the school is in session. The statute separately applies when the violation occurs “within 100 feet of a public park or playground.” Simple possession under § 34 is not one of the listed underlying violations.

Proximity alone does not establish the current offense. During the commission of the underlying violation, the Commonwealth must also prove one of the additional circumstances stated in § 32J. A conviction is punishable by a mandatory minimum two-year term that begins after the sentence for the underlying drug offense. The statute states that lack of knowledge of school boundaries is not a defense. See the firm’s complete analysis of Massachusetts drug charges near schools, public parks, and playgrounds.

Breaking and Entering

The breaking and entering statutes at M.G.L. c. 266, §§ 14 through 18 distinguish among nighttime and daytime offenses, dwelling houses and other buildings, whether a person was lawfully inside at the time, and whether the entry was made with intent to commit a felony or for some other purpose. The exposure depends on those distinctions, and it ranges from a house of correction term to life in state prison. The intent element is the one most often assumed rather than proved. See breaking and entering in Massachusetts.

Trespass

A person who enters or stays on property after the owner or another person in lawful control of the property forbids the person to be there can face a trespass charge under G.L. c. 266, § 120. A homeowner, a tenant, or a business owner who is being harassed can use a written no trespass notice to bar the harasser from the property. The firm’s page on trespass charges in Massachusetts explains what the Commonwealth must prove, the defenses, the penalties, and how to write and deliver a no trespass notice.

Assault and Battery

Assault and battery under G.L. c. 265, § 13A is a misdemeanor. If a defendant is convicted, the possible penalties are up to two and one-half years in the house of correction or a fine of up to $1,000. The charge is a felony under § 13A(b) when the assault and battery causes serious bodily injury, when the alleged victim is pregnant, or when the alleged victim holds a protective order. Assault and battery on a person sixty or older is a separate felony under § 13K.

The firm’s Massachusetts assault and battery page explains the three forms of battery, self-defense, the clerk-magistrate hearing, and accord and satisfaction.

Assault and Battery on a Police Officer

Assault and battery on a police officer or other public employee performing official duties is a separate crime under G.L. c. 265, § 13D. The basic offense is a misdemeanor. If the judge imposes a jail sentence, the minimum is ninety days. The judge may impose a fine instead. The Commonwealth must prove that the defendant knew the alleged victim was a police officer performing official duties. If a defendant is convicted of an assault and battery that caused serious bodily injury to an officer, the judge must impose at least one year of imprisonment.

The firm’s page on assault and battery on a police officer or public employee explains the elements, the 2026 amendment, the two felony versions of the charge, and the defenses.

Reckless Endangerment of a Child

Reckless endangerment of a child under G.L. c. 265, § 13L is a misdemeanor. If a defendant is convicted, the maximum sentence is two and one-half years in the house of correction. The Commonwealth must prove a substantial risk of serious bodily injury or sexual abuse to a child under eighteen. The Commonwealth must also prove that the defendant was personally aware of that risk and consciously disregarded that risk. The Commonwealth does not have to prove that the child was hurt.

The firm’s page on reckless endangerment of a child explains the elements, the appellate decisions on what counts as reckless conduct, the clerk-magistrate hearing, and the DCF investigation that can run alongside the criminal case.

Assault and Battery on a Child

A person accused of injuring a child under fourteen can be charged with assault and battery on a child under G.L. c. 265, § 13J. The Commonwealth must prove that the child suffered a bodily injury, which the statute defines as a substantial impairment of the child’s physical condition. If a defendant is convicted of causing bodily injury, the maximum sentence is five years in state prison. A parent or other caretaker can also be charged for wantonly or recklessly permitting another person to injure the child.

The firm’s page on assault and battery on a child explains the bodily injury element, the charges against a caretaker who permits an injury, the parental discipline defense, the medical evidence, and the penalties.

Spanking and Parental Discipline

A parent or guardian in Massachusetts can spank a child as discipline when the force is reasonable and related to the child’s welfare. The force also must not cause more than fleeting pain or minor, temporary marks. The Supreme Judicial Court set these requirements in Commonwealth v. Dorvil, 472 Mass. 1 (2015). A parent whose spanking fails one requirement can be charged with assault and battery under G.L. c. 265, § 13A. A parent who uses a belt or another object can be charged with assault and battery by means of a dangerous weapon.

The firm’s page on whether spanking a child is a crime in Massachusetts explains the three requirements, the appellate decisions that apply the three requirements, spanking with a belt, stepparents and teachers, and investigations by the Department of Children and Families.

Leaving a Child Home Alone

Massachusetts law sets no minimum age at which a parent can leave a child home alone. A parent who leaves a child home alone or in a car can still face a charge of reckless endangerment of a child under G.L. c. 265, § 13L, and a neglect investigation by the Department of Children and Families. The firm’s page on what age a child can stay home alone in Massachusetts explains the circumstances courts and DCF consider, the appellate decisions, and the defense of a parent accused of leaving a child alone.

Teachers and School Staff Accused of Assault, Threats, or Sexual Assault

A teacher, aide, coach, or other school employee accused of hitting, restraining, threatening, or sexually touching a student can be charged with a crime in Massachusetts. Public school staff have no right to use corporal punishment under G.L. c. 71, § 37G. If a teacher is convicted of indecent assault and battery on a child under fourteen, the judge must impose at least ten years in state prison because teachers are mandated reporters. A teacher accused of threatening a student can be charged under G.L. c. 275, § 2. The employee can also face a DCF investigation and action against a teaching license.

The firm’s page on teachers and school staff accused of assault, threats, or sexual assault explains the restraint regulations, the threat and harassment charges, the 2026 law on sixteen- and seventeen-year-old students, the DCF investigation, and the teaching license.

Criminal Charges Between Roommates

An argument between roommates over noise, rent or property can turn into an arrest or an application for a criminal complaint against a college student. The police and roommates commonly bring charges of assault and battery under G.L. c. 265, § 13A, threats to commit a crime under G.L. c. 275, § 2, malicious destruction of property under G.L. c. 266, § 127, larceny under G.L. c. 266, § 30, and criminal harassment under G.L. c. 265, § 43A. For a misdemeanor, the clerk-magistrate ordinarily gives the student notice and a hearing before issuing a complaint, under G.L. c. 218, § 35A.

The firm’s page on criminal charges between roommates explains how a roommate case begins, what a student should do after a roommate calls the police, the clerk-magistrate hearing, the penalties for each charge, the defenses, and the effects on school and immigration.

ADW and ABDW in Massachusetts

Assault by means of a dangerous weapon under G.L. c. 265, § 15B and assault and battery by means of a dangerous weapon under § 15A are separate felonies. ADW can be proved without physical contact, while ABDW requires a touching and may proceed under an intentional or reckless-injury theory.

The firm’s Massachusetts ADW and ABDW defense guide explains the elements, dangerous-weapon requirement, penalties, evidence, self-defense, and the difference between the two offenses.

AI Crimes in Massachusetts

Massachusetts prosecutors charge conduct involving artificial intelligence under existing statutes. Sharing an AI nude image of a real person can be charged as criminal harassment under G.L. c. 265, § 43A(b)(2). A voice clone scam can be charged as identity fraud under G.L. c. 266, § 37E. Secretly recording a conversation with an AI note taker can be charged as a felony under the wiretap statute, G.L. c. 272, § 99.

The firm’s page on AI crimes in Massachusetts explains these charges, the use of ChatGPT conversations as evidence, AI-made fake IDs, texts written by AI while a restraining order is in effect, and police facial recognition searches.
