In a quiet South Jersey town, a chilling plot unraveled, exposing a tale of vengeance that could have ended in tragedy. Jaclyn Diiorio, a 26-year-old woman from Runnemede, New Jersey, now sits behind bars, accused of orchestrating a murder-for-hire scheme targeting her former boyfriend, a 53-year-old Philadelphia police officer, and his 19-year-old daughter. The plan, which authorities say was driven by personal animosity, was thwarted by a confidential informant who alerted police, leading to Diiorio’s arrest on April 4, 2025. What began as a seemingly personal dispute escalated into a case that has gripped the region, raising questions about relationships, retribution, and the lengths one might go to settle a score.
The story began to unfold when Diiorio, who had recently ended her relationship with the officer, allegedly sought out someone to carry out the killings. Authorities say she offered $12,000 to a man she believed was willing to take on the job. Unbeknownst to her, the individual was working with law enforcement, feeding critical information to the Camden County Prosecutor’s Office. On April 3, investigators received a tip about the plot, prompting swift action. The following day, Diiorio met the informant in a parking lot along North Black Horse Pike in Gloucester Township. There, she handed over $500 in cash as a down payment, sealing her intent in the eyes of the law. Moments after the exchange, members of the Gloucester Township Police Department’s Special Response Team moved in, apprehending her without incident.
During the arrest, police discovered more than just evidence of the alleged plot. Diiorio was found in possession of a bottle containing suspected alprazolam pills, a prescription medication commonly known as Xanax, for which she reportedly had no valid prescription. This added a charge of possession of a controlled dangerous substance to an already grave list of accusations. Diiorio now faces two counts of first-degree attempted murder, one count of first-degree conspiracy to commit murder, and the third-degree drug possession charge. She was taken to the Camden County Correctional Facility, where she awaits a detention hearing scheduled for April 9, 2025, in Superior Court.
The investigation was a collaborative effort, with the Camden County Prosecutor’s Office Major Crimes Unit working alongside Gloucester Township Police and the U.S. Marshals Service’s New York/New Jersey Regional Fugitive Task Force. Authorities have remained tight-lipped about the specifics of Diiorio’s relationship with the officer, though it’s clear the breakup was contentious. The officer, whose identity has not been publicly disclosed, and his daughter were unharmed, thanks to the informant’s cooperation and the rapid response of law enforcement.
This case has sent ripples through Runnemede, a small community just eight miles from Philadelphia, where such schemes seem far removed from everyday life. For residents, the news is a stark reminder of how personal disputes can spiral into dangerous territory. Diiorio’s arrest underscores the critical role of informants in preventing violent crimes and the importance of coordinated efforts among law enforcement agencies. As the court date approaches, the public awaits further details, hoping to understand what drove a young woman to such extreme measures. For now, the officer and his daughter are safe, and a potential tragedy has been averted, leaving a community to reflect on the fragility of human relationships.
