An inmate at Natrona County Detention Center was found dead this morning, according to a sheriff's official.

Authorities haven't identified the 46-year-old man yet, but Natrona County Sheriff's Sgt. Mark Sellers said the inmate had been arrested in June by Mills police on drug possession charges.

There were no signs of foul play, Sellers said.

The investigation into the man's death will be handled by the Wyoming Division of Criminal Investigation.
