Source: Grave markers found, but no bodies at mental hospital

District police received a report that possible human remains were found in the basement of a former D.C.-run mental hospital in Laurel, but a department source on Wednesday told The Examiner that cadaver dogs found no evidence of remains.

Officials searched the basement of the Forest Haven mental hospital after learning there were what appeared to be makeshift graves — mounds marked by white crosses — in the basement, the source said. The facility has been closed since 1991. It opened in 1925 and was notorious for poor conditions and abuse.
