Philadelphia, PA Murder Defense Lawyer

A murder charge is the most serious criminal accusation a person can face under Pennsylvania law. A conviction may result in life imprisonment, decades of incarceration, or, in limited circumstances, the death penalty. Beyond the criminal penalties, a murder allegation can permanently affect every aspect of your life, including your family, career, financial future, and reputation.

If you have been arrested or are under investigation for murder in Philadelphia, the decisions you make immediately after learning of the investigation can significantly affect your case. Law enforcement officers often spend months or years building homicide prosecutions before making an arrest. By the time charges are filed, prosecutors may have assembled witness statements, forensic evidence, surveillance footage, digital communications, DNA evidence, and expert testimony intended to support a conviction.

At Young, Marr, Mallis & Associates, our criminal defense attorneys include former prosecutors who understand how murder cases are investigated, charged, negotiated, and tried. We have experience defending clients facing the most serious criminal allegations and are prepared to take difficult homicide cases to trial whenever doing so is in our clients’ best interests. When your freedom and future are on the line, you deserve experienced legal representation from dedicated Philadelphia murder defense lawyers who understand what is at stake.

Pennsylvania Divides Murder Into Three Degrees

Pennsylvania’s murder statute is found at 18 Pa. Cons. Stat. § 2502. Unlike many states, Pennsylvania divides murder into three separate degrees, each with different legal elements and dramatically different sentencing consequences. Understanding which degree of murder has been charged is one of the first steps in evaluating the prosecution’s case. Although all murder charges are extremely serious, the Commonwealth must prove different elements depending on the specific degree alleged. Because the penalties are severe and the legal issues are often complex, every murder prosecution requires careful preparation and a defense strategy tailored to the facts of the individual case.

First-Degree Murder

First-degree murder is the most serious homicide offense under Pennsylvania law. Under Section 2502(a), a criminal homicide constitutes murder of the first degree when it is committed by an intentional killing. The statute defines an “intentional killing” as a willful, deliberate, and premeditated killing. Prosecutors must prove beyond a reasonable doubt not only that the defendant caused another person’s death, but also that the killing was intentional within the meaning of the statute.

A conviction for first-degree murder carries the most severe penalties available under Pennsylvania law. Adult defendants face either life imprisonment without parole or, when the Commonwealth seeks capital punishment and statutory aggravating circumstances are established, the possibility of a death sentence following a separate penalty phase.

Because intent is such an important element of first-degree murder, these cases frequently involve extensive litigation concerning forensic evidence, witness credibility, mental state, self-defense, identification, and other factual and legal issues.

Second-Degree Murder

Second-degree murder is commonly known as Pennsylvania’s felony murder rule. Under Section 2502(b), a person commits second-degree murder when a criminal homicide occurs while the defendant was engaged as a principal or an accomplice in the perpetration of certain felonies. The statute defines “perpetration of a felony” to include offenses such as robbery, burglary, kidnapping, arson, rape, involuntary deviate sexual intercourse, and certain other qualifying felonies.

Unlike first-degree murder, prosecutors do not have to prove that the defendant intended to kill the victim. Instead, the Commonwealth must establish that the death occurred while the defendant was committing or participating in one of the qualifying felony offenses.

Historically, adult defendants convicted of second-degree murder received a mandatory sentence of life imprisonment. However, Pennsylvania law in this area has undergone significant constitutional developments, and sentencing issues continue to evolve. Because the applicable law can be complex, anyone facing second-degree murder charges should seek experienced legal representation immediately.

Third-Degree Murder

Third-degree murder is defined by Section 2502(c) as all other kinds of murder that do not qualify as first-degree or second-degree murder. Unlike first-degree murder, third-degree murder does not require proof of a deliberate and premeditated intent to kill. Likewise, it does not require that the death occur during the commission of one of the qualifying felonies necessary for second-degree murder.

Third-degree murder is generally charged when prosecutors allege that the defendant acted with the malice required by Pennsylvania law, but the facts do not satisfy the statutory requirements for first-degree or second-degree murder. Third-degree murder is graded as a felony of the first degree. In most cases, it carries a maximum sentence of up to 40 years’ imprisonment, although enhanced penalties may apply in certain circumstances, including cases involving prior convictions for crimes of violence.

Murder Investigations Are Thorough and Aggressive

Law enforcement agencies devote enormous resources to homicide investigations. Detectives often work closely with forensic scientists, medical examiners, ballistics experts, digital forensic analysts, and prosecutors throughout the investigation.

Evidence in murder prosecutions may include, for instance:

  • DNA testing
  • Ballistics and firearm evidence
  • Cell phone records and location data
  • Surveillance video
  • Social media communications
  • Search warrant evidence
  • Witness testimony
  • Autopsy findings
  • Digital forensic evidence

Because prosecutors often begin preparing for trial long before charges are filed, defendants should never attempt to handle these investigations without experienced legal counsel.

Building a Strong Murder Defense in Philadelphia

Every murder case presents unique legal and factual issues. The appropriate defense depends on the specific allegations, the available evidence, and the degree of murder charged. Depending upon the circumstances, defenses may include mistaken identity, self-defense, defense of another person, accident, lack of intent, insufficient evidence, mistaken eyewitness identification, unreliable forensic evidence, constitutional violations, or challenges to the prosecution’s expert testimony.

At Young, Marr, Mallis & Associates, we conduct our own independent investigation rather than relying solely on the government’s version of events. We carefully examine witness statements, forensic testing, digital evidence, surveillance footage, laboratory reports, and every other available source of evidence to identify weaknesses in the Commonwealth’s case. When appropriate, we work with independent experts in forensic pathology, ballistics, DNA analysis, crime scene reconstruction, toxicology, psychology, and digital forensics.

Former Prosecutors Defending the Accused

Our criminal defense team includes former prosecutors who understand how homicide cases are evaluated from the government’s perspective. We know how charging decisions are made, how prosecutors prepare witnesses, how forensic evidence is presented, and what strategies are commonly used during trial. That experience provides valuable insight when developing a defense strategy. We anticipate the prosecution’s arguments, identify evidentiary weaknesses, and prepare thoroughly for every stage of the proceedings. Our team is prepared to negotiate when doing so serves our clients’ interests, but we also prepare every murder case for trial. Prosecutors know we are willing to defend our clients aggressively before a jury whenever necessary.

Early Legal Representation Can Make a Difference

Many people first learn they are under investigation before they are formally arrested. Detectives may request an interview, execute a search warrant, or contact family members seeking information. If this happens, do not assume you can explain the situation on your own. Politely exercise your right to remain silent and contact an attorney immediately. Early representation allows your defense team to preserve evidence, locate favorable witnesses, retain experts, and begin protecting your constitutional rights before the prosecution’s case becomes even stronger.

Frequently Asked Questions

What is the difference between first-, second-, and third-degree murder in Pennsylvania?

Under 18 Pa. Cons. Stat. § 2502, first-degree murder involves an intentional, willful, deliberate, and premeditated killing. Second-degree murder applies when a death occurs while the defendant is committing or participating in certain qualifying felonies, even if there was no intent to kill. Third-degree murder includes all other killings committed with the malice required by Pennsylvania law that do not meet the statutory definitions of first-degree or second-degree murder.

What is Pennsylvania’s felony murder rule?

Pennsylvania’s felony murder rule is found in 18 Pa. Cons. Stat. § 2502(b). It allows prosecutors to charge second-degree murder when a death occurs during the perpetration of certain specified felonies, such as robbery, burglary, kidnapping, or arson. A person may be charged even if another participant caused the death.

Can someone be charged with murder even if they did not personally kill the victim?

Yes. Under Pennsylvania law, a person may face second-degree murder charges if they were an accomplice or principal participating in the perpetration of a qualifying felony during which a death occurred. Accomplice liability may also apply in other circumstances depending on the facts of the case.

What sentence does third-degree murder carry in Pennsylvania?

Third-degree murder is generally graded as a first-degree felony. In most cases, it is punishable by up to 40 years’ imprisonment, although Pennsylvania law authorizes enhanced penalties in certain situations, including when the defendant has a prior conviction for a crime of violence.

Should I speak with detectives if they want to ask me questions about a homicide?

Not before consulting with an attorney. Even if you believe you can explain your involvement or clear up a misunderstanding, statements made during a homicide investigation can become important evidence in court. An experienced murder defense attorney can protect your rights and advise you before any interview takes place.
