BOISE, Idaho -

State corrections officials say an inmate was found dead in his cell at the Idaho Maximum Security Institution south of Boise.

Ray says Dominguez was found hanging in his cell at 6:15 p.m. Wednesday. Prison staff called paramedics and tried to resuscitate Dominguez, but he was pronounced dead about 45 minutes later.

IDOC officials and the Ada County sheriff's office are investigating the death.

Dominguez had been convicted of aggravated battery, assault and battery on a correctional officer.
