Federal case opened against N.J. woman accused of Tinder murder-for-hire plot
Jaclyn Diiorio, of Runnemede, is expected to plead not guilty to two new charges in U.S. District Court in Philadelphia on Monday, her attorney said.
Federal prosecutors are now involved in the case of a Camden County woman accused of trying to hire a hitman she met on the dating app Tinder to kill her cop ex-boyfriend and his teenage daughter.
Jaclyn Diiorio, 28, of Runnemede, was charged this month with two counts of using interstate commerce facilities — in her case, a cell phone — in an attempt to commission a murder-for-hire, according to an indictment unsealed Wednesday.
Federal prosecutors will now be tasked with prosecuting Diiorio after Camden County prosecutors dropped their case against her in response to the charges.
It’s the latest development in a story that captured national attention from true-crime enthusiasts and curious readers alike.
In April 2025, Diiorio was charged with two counts of attempted murder, conspiracy, and related crimes for the plot, which Camden County prosecutors said involved Diiorio trying to have both her ex-boyfriend, Philadelphia Police Officer Matthew O’Hanlon, and his 19-year-old daughter killed.
Prosecutors said Diiorio met the would-be hitman on Tinder. After days of exchanging messages and calls, they said, the two met in a Gloucester Township Dollar General parking lot, where Diiorio gave the man $500 of a proposed $12,000 payment before being swiftly arrested.
The hitman, prosecutors said, was actually an informant working with Camden County detectives who days earlier had tipped them off to Diiorio’s request.
And it was not Diiorio’s first attempt at having O’Hanlon and his daughter killed, prosecutors added.
They alleged the New Jersey hairdresser told the informant she’d previously been misled by others who’d given her “fake pictures” of a supposed completed contract killing.
Prosecutors said the tumultuous relationship between Diiorio and O’Hanlon ended about a month before the murder-for-hire plot fizzled.
The federal indictment, filed Sept. 3 in the U.S. District Court for the Eastern District of Pennsylvania, offers few new details in the case.
It says Diiorio used a cell phone to facilitate an interstate plan to murder two individuals identified as Person #1 and Person #2.
Communications took place between March 30 and April 5, 2025, in both Pennsylvania and New Jersey, according to the document.
Diiorio’s defense attorney, Robert Gamburg, said his client planned to plead not guilty to the charges during a detention hearing before U.S. Magistrate Judge Scott W. Reid on Monday.
Earlier this year, Gamburg sought to dismiss charges in Diiorio’s Camden County case when he filed a motion accusing prosecutors of relying on information that he said had been gathered by entrapment.
Gamburg said the informant who led police to Diiorio was desperate for money, and frequently brought unsolicited information to the sheriff’s department in exchange for cash.
The filing also describes the informant as a rogue operator, one whose phone and text conversations with Diiorio went unmonitored by detectives for days as they orchestrated her arrest.
County prosecutors declined to comment on the allegations at the time and said the matter would be resolved in court.
Reached by email Wednesday, a spokesperson for U.S. Attorney’s Office for the Eastern District of Pennsylvania declined to comment on the indictment.
A conviction for using interstate commerce facilities to commission a murder-for-hire has a maximum sentence of 20 years in prison.
