A man accused of breaking into a historic cemetery near Philadelphia was found with about 100 human skulls, mummified body parts, and decomposing torsos, officials said. Jonathan Christ Gerlach, 34, was arrested near Mount Moriah Cemetery, an abandoned burial ground with about 26 broken mausoleums and vaults since early November. Officers spotted bones inside his parked vehicle near the cemetery, leading to the arrest. At Gerlach's home and a storage unit, investigators found more than 100 skulls, bones, mummified hands and feet, and two decomposing torsos. Delaware County District Attorney Tanner Rouse noted the remains varied in condition—some were whole, others partial, and some skulls were placed on shelves. Jewelry taken from graves and even a pacemaker still attached to one body were recovered. Authorities linked Gerlach to the crimes based on license plate data showing his repeated visits near the cemetery during the break-in period. He was caught carrying a crowbar and a burlap bag holding mummified remains of two children, three skulls, and more bones. Gerlach admitted to taking about 30 sets of remains and showed officers the graves he targeted. Mount Moriah Cemetery, founded in 1855, covers roughly 160 acres with about 150,000 graves. Police say Gerlach damaged vaults and mausoleums to get inside. The motive remains unknown. "Given the scale of what we are dealing with, it is difficult at this stage to say exactly why this happened," said DA Rouse. Gerlach faces 100 counts each of abuse of a corpse and receiving stolen property, plus various counts of burglary, theft, trespassing, and desecration of historic burial sites and objects. He is held on a $1 million bond. Identifying and returning the remains will take time due to the large number and age of the graves.
