Authorities say an inmate at the county jail had a makeshift metal knife and a handmade bong.
During a search of the Lewis and Clark County Detention Center, officers found a two-inch piece of metal that had been made into a shank, court documents state. The metal had been sharpened on one end and wrapped in a braided bed sheet on the other.
"The item could have been easily used as a deadly weapon if used to stab someone," according to court documents.
In addition to a water bottle modified to smoke marijuana, authorities say they also found a playing card that had been rolled into a pipe with a metal top of a pencil used as the bowl to hold the drugs. The bottle and card smelled of marijuana, court documents note.
For the items, the inmate, William Paul Cox, 34, faces a felony charge of possession of a deadly weapon by a prisoner and a misdemeanor charge of criminal possession of drug paraphernalia.
Officials say the items were found in a cell solely occupied by Cox, who is a probationer facing drug dealing and possession charges.
