Police on Sunday released the identity of an armed man shot to death by a Madison County Sheriff's Department deputy during a confrontation on Friday.

Illinois State Police Capt. James Morrisey said the man killed was Barry Cloninger, 51, of rural Edwardsville. An autopsy was done Saturday.

The deputy, whose name has not been released, is on administrative leave, which is routine in an officer-involved shooting.

The Sheriff's Department called Illinois State Police to investigate the fatal shooting.

Sheriff Bob Hertz released this account of what happened:

Deputies received a call at 10:13 p.m. from a resident in the 7100 block of Illinois 140 in Fort Russell Township. The resident reported suspicious activity at his residence and requested deputies to respond to investigate.

Deputies arrived about four minutes later. After speaking to the complainant, deputies went to a home next door to further investigate. When approaching that residence, deputies were confronted by a man armed with a gun outside the residence.

"A confrontation with that armed man ensued and he was subsequently shot by a deputy sheriff," the statement read.

The man was pronounced dead at the scene.
