GRADY, Ark. (AP) - Arkansas prison officials say a 35-year-old inmate has died after he was found unresponsive in his cell at a maximum-security unit.
The Arkansas Department of Correction says Ronnie Martin was pronounced dead Tuesday night at the Cummins Unit.
Martin was serving a 20-year sentence out of Cleburne County on a drug charge.
His death comes as officials and lawmakers look into the suspected drug overdoses of five inmates who died last month at a different Arkansas prison. Arkansas Department of Correction spokesman Solomon Graves says there's no indication that Martin's death is linked to the earlier deaths and that there was nothing conclusive showing drugs were involved.
Graves says a final cause of death will be determined following an autopsy and investigation.
