Bones found at Horsch "house of horrors" in Olney section of Philadelphia, sources say

Bones were discovered outside the so-called house of horrors in the Olney section of Philadelphia, but it's unclear whether they are related to the ongoing investigation into Raymond "R.C." Horsch, a suspected serial killer who died last year, sources told CBS News Philadelphia on Thursday. The Philadelphia Medical Examiner's Office responded to the house at 417 West Chew Ave. on Thursday, sources close to the investigation confirmed. The bones were found in the backyard, where agents and detectives have been painstakingly searching for any sign of human remains and any evidence of at least seven women connected to Horsch and the house, some of whom are feared dead, sources told CBS News Philadelphia. It's not clear whether they were human or animal bones, sources stressed. More testing is needed to determine the bones' origin and whether they are connected to the investigation.Authorities outside the "house of horrors" in the Olney section of Philadelphia.
