State police Sgt. Kim Riley said a relative of one of the girls dropped them off near a railroad bridge. Another relative agreed to pick them up later, after the girls went hiking, but the girls never showed up to the location they were supposed to.

Riley would not reveal the girls’ manner of death, citing the investigation.

On Wednesday, authorities released the photo of a man seen walking on a trail near the location where the girls went missing. They want to talk to him to see if he saw anything, reports Fox 59.

The FBI is assisting local and state police with the investigation.

Carroll County Sheriff Tobe Leazenby said there are currently no suspects.

“There is someone out there that did this crime and we’re going to track them down,” said Leazenby.
