In Pennsylvania, there are several types of criminal homicide. A person may be guilty of first-degree murder, second-degree murder, or third-degree murder. There are also two levels of manslaughter - voluntary manslaughter and involuntary manslaughter.
All of these crimes involve the unlawful death of a human being. The most serious type of homicide is murder in the first degree.
This article will examine how Pennsylvania’s first-degree murder laws work. It also explains the penalties and defenses to this crime.

Proving First-Degree Murder in Pennsylvania
All kinds of murder involve the intentional killing of another human being. Pennsylvania law requires proof of premeditation and malice aforethought for a murder conviction. With manslaughter, the state doesn’t have to prove either of these things.
In a murder case, the prosecutor can establish express or implied malice. In a first-degree murder case, the state must prove that the defendant acted with express malice. They must also prove the defendant had a specific intent to kill. They can do this by demonstrating that the defendant used a deadly weapon or lied in wait for their victim.
Possibility of the Death Penalty
First-degree murder is one of the most serious crimes in Pennsylvania and generally results in the most severe punishments available under state law. In Pennsylvania, people guilty of first-degree murder are eligible for the death penalty.
Pennsylvania is one of the states that still has the death penalty. Lawmakers reserve this punishment for a handful of crimes, including first-degree murder. The law is very clear on when a person is at risk of a death sentence.
According to Pennsylvania Statutes Title 18 Pa.C.S. Section 1102, the following people are eligible for the death penalty:
- Anybody guilty of first-degree murder
- A person guilty of killing a law enforcement officer
It’s worth mentioning that there has not been an execution in Pennsylvania since 1999. In 2015, then-Governor Tom Wolf imposed a moratorium on executions. This moratorium is still in effect in 2025.
First-Degree Murder vs. Second-Degree Murder
What distinguishes first-degree murder from second-degree murder in Pennsylvania is the defendant’s intent and state of mind. A first-degree murder conviction requires that the state prove premeditation, planning, and deliberate acts on the part of the defendant.
Second-degree murder is when a person intends to kill the victim but does not plan it. In second-degree murder cases, the prosecutor does not have to prove the same level of malice as they do in a first-degree murder case.
Felony Murder Is Second-Degree Murder in Pennsylvania
Many states classify felony murder as first-degree murder. This isn’t the case in Pennsylvania. Pennsylvania does follow the felony murder rule, but when someone dies during the defendant’s commission of a felony, the state can charge that person with second-degree murder.
The punishment for second-degree murder is less severe than it is for first-degree murder. If the court finds you guilty of first-degree murder, the judge can impose the death sentence. However, the maximum sentence for second-degree murder is life imprisonment without the possibility of parole.
While your criminal defense lawyer can certainly introduce evidence of mitigating factors, a first-degree murder conviction in Pennsylvania carries a mandatory life sentence.
