A two-month-long investigation into a string of burial site desecrations at Mount Moriah Cemetery on Philadelphia’s outskirts had a breakthrough on Tuesday when authorities arrested a 34-year-old man now accused of hoarding more than 100 sets of human remains at his home and storage unit.
Detectives conducting surveillance at the 160-acre cemetery found bones and skulls scattered across the back seat of a vehicle owned by the suspect, identified as Jonathan Christ Gerlach, before taking him into custody as he carried a crowbar and a burlap bag containing mummified remains of two children, three skulls, and additional bones.
When investigators searched Gerlach's Ephrata home and storage unit, they uncovered human remains in drastically different conditions. Most were in the home's basement, authorities said.
"They were in various states. Some of them were hanging, as it were. Some of them were pieced together, some were just skulls on a shelf," Delaware County District Attorney Tanner Rouse said.
Among the recovered items were more than 100 human skulls, two decomposing torsos, long bones, mummified hands and feet, and other skeletal materials. A pacemaker remained attached to one of the remains.
The investigation began in early November when authorities received reports of break-ins at Mount Moriah Cemetery in Yeadon. At least 26 mausoleums and vaults had been forcibly opened over subsequent months.
The breakthrough came when investigators checked Gerlach’s license plates and discovered that his car had been documented repeatedly in the Yeadon area during the period when the cemetery burglaries were occurring. This evidence prompted detectives to conduct surveillance at the cemetery, eventually leading to Gerlach’s arrest on Tuesday.
The DA’s office said officers witnessed Gerlach leaving the cemetery while holding the burlap bag, crowbar, and other assorted items. When brought into custody, the suspect admitted to taking approximately 30 sets of human remains and identified the specific graves he had stolen from to investigators.
"Given the enormity of what we are looking at and the sheer, utter lack of reasonable explanation, it's difficult to say right now, at this juncture, exactly what took place. We're trying to figure it out," Rouse told reporters.
He also addressed the emotional impact of the case on affected families, stating, "Detectives walked into a horror movie come to life in that home. It is truly, in the most literal sense of the word, horrific. I grieve for those who are upset by this, who are going through this, who are trying to figure out if it is in fact one of their loved ones."
Police determined that Gerlach specifically targeted sealed mausoleums and underground vaults containing older burials, causing extensive damage to stonework and structural components to access the remains within. Officers also recovered jewelry they believe was linked to the graves and the cemetery.
He is currently being held at the George W. Hill Correctional Facility, with bail set at $1 million. A preliminary hearing is scheduled for Jan. 20. No attorney was listed in court records as of press time.
The Delaware County District Attorney's Office confirmed that the investigation remains ongoing. Mount Moriah Cemetery clarified that the incidents were confined to mausoleums and underground vaults, with no other areas of the grounds appearing to be affected.
