The investigation of a skull found in Fleming County indicates there were remains of two people at the site, according to Kentucky State Police.
Authorities searched the area after the skull was found and located more skeletal remains.
New information received Wednesday on an analysis of the remains indicates they were from two people, one taller than the other, state police said.
The skull is believed to be that of an Anglo or Hispanic man between 18 and 30 years old, state police said in a news release.
The preliminary findings also indicate the remains had been in the area from six months to two years, state police said.
There is no information yet on the cause of death of the two people, said Trooper Endre Samu, spokesman for the Morehead state police post.
Police have asked that anyone with information about the remains call the post at (606)784-4127.
