Understanding Murder Charges in Massachusetts
In Massachusetts, Murder is governed by Massachusetts General Laws Chapter 265, Section 1. The law defines this as the unlawful killing of a human being with malice aforethought.
There are two classifications of Murder under Massachusetts law:
- First-Degree Murder: This includes killings committed with deliberate premeditation, extreme atrocity or cruelty, or during the commission of a felony (commonly known as felony murder).
- Second-Degree Murder: All other types of murder committed with malice, but without the circumstances that elevate it to first degree.
The penalties are life-altering. First-degree murder carries a mandatory life sentence without the possibility of parole. Second-degree murder also carries a life sentence, though the defendant may be eligible for parole after 15 years.
These penalties make it crucial to have a Boston criminal defense attorney who is familiar with every stage of the legal process—from arraignment to trial.

What to Expect if You're Charged with Murder
Being charged with Murder in Massachusetts initiates a series of legal events that can move quickly. You may be arrested, arraigned, held without bail, and indicted by a grand jury. From that point, the Commonwealth prepares its case—and so should you.
You’ll need a Boston defense attorney who knows how to:
- Investigate the underlying facts and timeline
- Work with expert witnesses (forensic, psychiatric, etc.)
- Challenge unlawful searches or interrogations
- Negotiate when appropriate, or go to trial when necessary
