Mystery shrouds the death of a woman after hikers came across her severed foot in a sneaker at a national park.
The FBI said the foot was found at Catoctin Mountain Park in Thurmont, in the US state of Maryland, on Saturday.
FBI spokeswoman Joy Jiras said the hikers discovered a separated foot in a remote area well off any established paths. The rest of the body was found less than 90 metres away but was missing her other foot and one hand.
Ms Jiras told The Frederick News-Post there had been no reports of missing people in the park or abandoned vehicles nearby.
She added there are also no surveillance cameras in the area.
The FBI said the woman had long, dark hair with braids, and was wearing a black tracksuit, wrist guard, and red coloured Nike shoes.
She was also found with a Puma handbag and a set of keys, containing an El Salvador keychain, authorities said.
The cause of the woman’s death is still unknown and it’s unclear how long the body was in that location, officials said.
Richard Ruggieri, an FBI special agent, told The Washington Post, “everything is on the table” in considering how she might have died.
"This person has a story to tell,” he told The Post.
“First, we need to figure out who it is to tell the story."
An autopsy will determine how the woman died.
The National Park Service is also helping the FBI with the investigation.
