GRADY — Authorities say a 29-year-old Arkansas inmate incarcerated for a drug conviction has died after being found unresponsive on the floor of his cell.

The state Department of Correction said in a statement that Christian Smith was found Friday afternoon in the cell he shared with another inmate at the Cummins Unit in Grady, southeast of Pine Bluff.

He was taken to a unit infirmary where he died. State correction officials did not provide any preliminary information on a cause of death.

State police are investigating.

Smith was nearing the end of a five-year prison term for drug possession and last year had seven disciplinary violations at the Cummins Unit.
