Baltimore County homicide detectives are investigating after the discovery of “possible human remains” at the county’s refuse/recycling center on West Warren Road in Cockeysville.

Police said they were called to the facility, which accepts waste and recycling from multiple jurisdictions, around 9 a.m. Monday. The county Department of Public Works and Transportation said the facility was “closed for the rest of the day.”

Around midnight Tuesday, police said “all” possible human remains were sent to the Office of the Chief Medical Examiner and that an autopsy is pending. Detectives are continuing to investigate the “origin” of the remains and determining whether the situation is criminal.

Police said they could not share when the remains were transferred in order to “maintain the integrity of this ongoing investigation.”

The county’s central acceptance facility was operating with its usual hours again on Tuesday.

The potential human remains were discovered indoors on a conveyor belt at the facility, said police spokeswoman Joy Lepola-Stewart. No arrests have been made. In an email, police said no additional remains had been discovered.
