PERU, Ind. (AP) — An inmate at a northern Indiana prison has been convicted in a 2020 attack on a correctional officer who was slashed in the face with a razor blade, leaving him with a permanent scar.

A Miami County jury found 67-year-old Raul Sotelo guilty Thursday of attempted murder, battery with bodily injury to a public safety officer and other charges in the July 1, 2020, attack.

The Kokomo Tribune reports Sotelo attacked the correctional officer with a razor blade wrapped with cardboard, slashing the left side of his face. The officer’s wound left him with a permanent 5-inch-long scar. Sotelo’s sentencing is scheduled for May 4.
