A quarter-century of waiting ends with the arrest of Richard Leidy, 60, in connection to the 1999 Philadelphia murder of Guerino “Gino” Marconi. This development brings renewed focus on cold case justice. On Monday, August 25, 2025, Leidy was charged not only with Marconi’s murder but also with the attempted murder of Marconi’s girlfriend at the time, Patricia Miley. The arrest marks a significant breakthrough in a case that has haunted South Philadelphia for decades.
The Key Players
The case revolves around three central figures: Richard Leidy, now the accused; Guerino “Gino” Marconi, the deceased; and Patricia Miley, the surviving victim. Understanding their roles is crucial to understanding the gravity of the charges.
Guerino “Gino” Marconi
Guerino “Gino” Marconi, 42 at the time of his death, had alleged ties to organized crime. Media reports identified him as a low-level associate of Joseph Salvatore “Skinny Joey” Merlino, who, according to these reports, was the reputed boss of the Philadelphia crime family in 1999. These connections have led investigators to consider the murder as potentially mob-related, as reported by FOX 29 Philadelphia.
Patricia Miley
Patricia Miley, then 31, was Marconi’s girlfriend and a victim of the same attack. Shot three times, she miraculously survived, becoming a key witness in a case that remained cold for over two decades. Her testimony and any evidence she provided have been crucial to the ongoing investigation, though the specifics of this are not yet public, according to 6abc Action News.
Richard Leidy
Richard Leidy, now 60, stands accused of murder, attempted murder, and multiple related charges. His arrest, occurring a mere block from the original crime scene, adds another layer of intrigue to the case. The charges against him include murder, attempted murder, aggravated assault, possession of a firearm, possession of an instrument of crime, simple assault, recklessly endangering another person, and unauthorized use of a motor vehicle, as detailed in court documents.
The Events of April 10, 1999
The night of April 10, 1999, marked a turning point for all involved. The brazen attack and subsequent investigation have shaped the lives of the victims and their families.
The Shooting
According to law enforcement sources, Marconi and Miley were ambushed outside Marconi’s residence on the 2400 block of South 20th Street in South Philadelphia. An assailant, armed with a rifle, opened fire on the couple. Marconi was struck by a single bullet to the head and died the following day, April 11, 1999. Miley sustained three gunshot wounds but survived. The Pulse of NH reported on the initial details of the shooting at the time.
Evidence and Aftermath
In an apparent attempt to conceal evidence, the gunman allegedly set fire to a van parked in front of Marconi’s home, as well as other vehicles in the vicinity. A weapon was recovered at the scene, though details about its type and any forensic analysis have not been publicly disclosed. These details contribute to the narrative of a carefully planned and executed crime, consistent with a mob-style hit.

Location and Timing
The geographical and temporal aspects of this case provide crucial context to the events and the subsequent investigation.
The Crime Scene
The shooting occurred on the 2400 block of South 20th Street in South Philadelphia. This residential area became the focal point of the investigation, with police meticulously combing the scene for clues. The proximity of Leidy’s residence to the crime scene – approximately one block away – has raised questions about his potential involvement and knowledge of the events, as noted by ABDPost.com.
Arrest and Legal Proceedings
Richard Leidy was arrested on Monday, August 25, 2025, at his home in South Philadelphia. He was arraigned on either Tuesday, August 26, or Wednesday, August 27, 2025, and did not enter a plea. Leidy is currently being held in federal custody without bail. A preliminary hearing has been scheduled for September 15, 2025, coinciding with Leidy’s 61st birthday. The timing of the arrest, 26 years after the murder, underscores the persistence of law enforcement in pursuing cold cases.
Unraveling the Motive
The question of motive remains central to understanding the crime. While authorities have not yet disclosed an official motive, several factors point to potential explanations.
Mob Ties and Potential Rivalries
Given Marconi’s alleged association with the Philadelphia crime family, the murder has been widely characterized as a mob-style killing. This suggests that the motive could be linked to organized crime activities, such as drug dealings or rivalries within the underworld. However, these remain speculative, pending further investigation and disclosure from law enforcement sources.
Cold Case Developments
The details that prompted investigators to make an arrest after 26 years remain undisclosed. The resurfacing of old news footage showing Richard Leidy being interviewed shortly after the 1999 murder, where he expressed concerns for his family’s safety, adds another layer of complexity to the case. This footage, available on various YouTube news segments, provides a glimpse into the atmosphere of fear and uncertainty that permeated the community at the time.
Impact and Implications
The arrest of Richard Leidy has far-reaching implications, both for the individuals involved and for the broader community.
Seeking Justice
Leidy’s arrest brings a long-awaited measure of justice for the Marconi family, who have endured years of uncertainty and grief. It also serves as a reminder that law enforcement agencies remain committed to solving cold cases, no matter how much time has passed. The arrest has reignited discussions around unsolved crimes and the pursuit of justice, as seen in numerous online forums and news commentaries.
Legal Proceedings and Community Response
As the case moves forward, all eyes will be on the legal proceedings. Leidy’s defense strategy, the evidence presented by the prosecution, and the testimony of witnesses will all play crucial roles in determining the outcome. The community’s response to the arrest and the subsequent trial will also be closely watched, as the case has reopened old wounds and sparked renewed interest in the history of organized crime in Philadelphia.
The arrest of Richard Leidy in connection with the 1999 murder of Gino Marconi marks a pivotal moment in a case that has remained unsolved for over two decades. While the details surrounding the motive and the evidence that led to the arrest remain largely undisclosed, the development offers a glimmer of hope for justice and closure for the victims’ families. As the legal proceedings unfold, the case will undoubtedly continue to captivate the attention of the community and serve as a reminder of the enduring impact of unsolved crimes.
