A man identified as 34-year-old Jonathan Gerlach is charged with burglary, abuse of corpse, and related offenses after authorities say he stole remains from gravesites across several Pennsylvania counties, leading to the discovery of more than 100 skulls, mummified parts, and other items.

Mount Moriah Cemetery in Philadelphia, dating to 1855 and spanning about 160 acres with roughly 150,000 graves, is the main site associated with the case, including the Prichard family mausoleum built in the early 1900s.

The preliminary hearing had been postponed after a prior no-show; on the current date he waived the hearing.

A formal arraignment is scheduled for June 3.

Relatives of victims, such as Judy Prichard McCleary, spoke about the harm to families and urged tougher controls on selling body parts online, highlighting a broader grave-site crime concern.

In court, Gerlach spoke little and wore a lime green prison jumpsuit, differing from his booking photo.

Gerlach is jailed in Delaware County Prison on a $1 million bail, with the June 3 arraignment expected to be waived.

The case involves cooperation among multiple agencies, including Delaware County detectives and Ephrata Police, with the arraignment planned at the County Courthouse and ongoing jail detention on $1 million bail.

Authorities note uncertainty about the total remains stolen and whether more charges will follow as the case progresses.

Investigators are identifying all remains and arranging reburial for victims’ families as part of the ongoing proceedings.

Gerlach waived his preliminary hearing at the Delaware County Courthouse, with prosecutors moving forward to determine guilt in court.
