Philadelphia police are investigating after human remains were discovered Thursday afternoon in an area behind the Woodford Mansion in Fairmount Park.
Authorities said the body was found around 3:15 p.m. by the Woodford Mansion caretaker.
The body was described as severely decomposed and police were unable to immediately determine the victim's gender or race.
The city-owned museum houses a collection of American, British and European decorative arts curated by Naomi Wood, a Philadelphia-born collector. The property was built in the mid-18th century by William Coleman, a city merchant and close friend of Benjamin Franklin.
An investigation into the body found on Thursday remains ongoing.
