Warlock member killed recruits in graveyard, corpse hidden in crypt: Philly DA

He couldn’t bury this secret forever.

A member of a notorious Philadelphia motorcycle gang was found guilty of murdering a potential member in a cemetery and dumping his body in a nearby crypt.

Michael DiMauro, a member of the Outlaw Warlocks, was found guilty Tuesday of killing 33-year-old David Rossillo Jr. in 2017. This was announced by the office of District Attorney Larry Kasner.

The 51-year-old, who was representing himself in court, was convicted after a brief jury deliberation on all charges including first-degree murder, conspiracy and abuse of a corpse.

DiMauro and Rossillo met at Mount Moriah Cemetery in southwest Philadelphia after a member of the cemetery’s nonprofit board let them in, the prosecutor’s office said.

There, DiMauro shot the Warlock recruit multiple times.

DiMauro then “tied a rope around Rossillo’s neck and then used a vehicle to drag his body to a crypt before breaking open the crypt and dumping the body inside,” according to a press release from the prosecutor’s office.

Two cooperating witnesses suspected the gangster.

Three years later, in April 2020, investigators found Rossillo’s body, as well as the remains of 36-year-old Keith Palumbo — a Delaware County musician. Both were identified using DNA samples in August 2020.

DiMauro was arrested the following month.

Another member of the Warlocks gang, Michael DeLuca, was arrested in 2021 and pleaded guilty to third-degree murder in the January 2023 Palumbo killing. Three other co-conspirators pleaded guilty to their role in disposing of the bodies.

The motives for both murders are still unclear, said Lasner’s office.

“We are committed to bringing justice to unresolved cases like this,” Krasner said in a statement. “I believe these convictions should send a message to anyone who believes they can murder others and hide the evidence of their heinous crimes: we will solve these cases and bring you to justice.”

DiMauro will be sentenced to life in prison without the possibility of parole later this month, the state attorney’s office said.
