Understanding Assault with Intent to Murder in Massachusetts
Under Massachusetts General Laws Chapter 265, Section 15, assault with intent to murder is classified as a felony. Unlike simple assault or assault and battery, this charge involves not only the allegation of an assault but also the claim that the accused acted with the specific intent to kill. The Commonwealth must prove three key elements beyond a reasonable doubt: that an assault occurred, that the accused intended to kill the alleged victim, and that the act was carried out with malice aforethought.
Because proving intent is often the most difficult part of the prosecution’s case, the state frequently relies on circumstantial evidence such as statements, the nature of the weapon used, or the severity of injuries. This makes having a skilled criminal defense lawyer essential.
Penalties for Assault with Intent to Murder
The penalties for this offense are severe. A conviction can result in up to ten years in state prison, and in aggravated cases, such as when the alleged victim is a police officer or public official, the potential sentence can increase to twenty years. In addition to prison time, you may face a lifetime of consequences, including a permanent felony record, the loss of your firearms rights, and barriers to employment and housing. For non-citizens, a conviction can also trigger deportation or other devastating immigration consequences.
Why Choose the Law Office of Matthew W. Peterson?
When you are accused of a crime as serious as assault with intent to murder, you need more than just a defense lawyer—you need a team that knows how the prosecution thinks and how to dismantle their case. At the Law Office of Matthew W. Peterson, we bring the perspective of a former prosecutor who understands the strategies the Commonwealth uses and how to challenge them effectively. We thoroughly investigate the evidence, question the credibility of witnesses, and scrutinize forensic details that may be unreliable or misleading.
Our defense strategies are always tailored to your situation, whether that involves proving the absence of intent, raising self-defense, or challenging the sufficiency of the Commonwealth’s evidence. Throughout the process, we maintain clear communication, keep you fully informed, and use our knowledge of the local courts in Suffolk, Essex, Middlesex, and Norfolk Counties to your advantage.
Defenses Against Assault with Intent to Murder
Although every case is unique, there are several defense strategies that may apply. One of the most common is to argue that there was no actual intent to kill, but rather an intent only to scare or injure, which can significantly reduce the severity of the charge. In some situations, the defense may focus on self-defense or the defense of others, especially if the accused reasonably believed that they were in immediate danger of death or serious harm.
In other cases, mistaken identity or unreliable witness testimony may be the issue, and the defense can challenge the accuracy of the state’s evidence. Sometimes, the prosecution’s entire case can collapse if the evidence was obtained unlawfully, violating the defendant’s constitutional rights. Our attorneys carefully examine all of these possibilities to build the strongest defense possible.
What to Expect After Being Charged
Being charged with assault with intent to murder begins a legal process that can feel overwhelming without experienced guidance. The first step is the arraignment, where the charges are formally read in court and a plea is entered. After that, the case moves into the pretrial stage, where motions may be filed to suppress evidence, dismiss charges, or challenge procedural errors. Discovery follows, during which the defense reviews police reports, medical records, video evidence, and witness statements.
If the case cannot be resolved through dismissal or negotiation, it proceeds to trial, where our attorneys present a vigorous defense and challenge the prosecution’s claims at every turn. If a conviction occurs, the sentencing phase determines the penalty, and we advocate for the most favorable outcome possible, including probation, reduced sentences, or alternative programs.

Yes. If the Commonwealth cannot prove intent to murder beyond a reasonable doubt, the charge may be reduced to aggravated assault or assault with a dangerous weapon.
What if I acted in self-defense?
Self-defense can be a powerful argument if you reasonably believed you were protecting yourself or someone else from death or serious injury.
How much prison time could I face if convicted?
A conviction carries up to ten years in state prison, or up to twenty years in aggravated cases.
Should I talk to the police if accused?
