MANSFIELD, La. — A Texan arrested in March after construction workers saw him on his hands and knees eating mud and growling has pleaded guilty in Louisiana to possession of cocaine.

District Attorney Richard Johnson says a plea agreement reached Thursday during pretrial conferences means Terence Loyd, 32, of Lufkin, Texas, will spend the next five years in prison. Lloyd initially had faced a string of drug charges.

Johnson says all but the cocaine possession charge were dropped in exchange for Loyd's plea.

Loyd was arrested after workers saw him rolling in mud and acting like a dog. Loyd had ingested so much mud that he started throwing up mud when he was jailed.

Authorities suspected the use of a hallucinogenic drug contributed to Loyd's delusions.
