MACKINAW — A Tazewell County Sheriff's Office deputy shot and killed a man who apparently pointed a gun at police Friday at a rural Mackinaw residence, authorities said. 

At about 9:30 a.m., deputies were sent to 34368 Illinois Route 9 after a 911 call reporting a man armed with an ax and a knife was trying to break into a gun cabinet, Tazewell County Sheriff Robert Huston stated in a news release.

When a Mackinaw Police Department officer and two county deputies arrived, the man pointed a gun at them, the release stated, based on preliminary reports.

One of the deputies fired in self defense.

The man was hit and taken to OSF HealthCare Saint Francis Medical Center in Peoria. He was pronounced dead in the St. Francis emergency room at 10:40 a.m., Peoria County Coroner Jamie Harwood said.

The deputy who fired the fatal shot was taken to UnityPoint Health-Methodist in Peoria, examined and released. The unidentified officer is a 25-year veteran, the release stated.

No deputies were hit by gunfire, Huston told the Journal Star. He said he didn't know if the dead man fired his weapon.

The deceased was 18, Harwood said. He had a history of mental illness, according to multiple sources.

The man's name and his address were being withheld pending notification of family, Harwood said. The coroner did say the man was from rural Mackinaw but it was unclear if the incident occurred at his home. 

The man's parents resided at the Route 9 address, Huston said. He also said deputies had been called to the home previously.

Harwood said the man suffered multiple gunshot wounds. A release from the coroner's office later in the day also did not specify a number of wounds. An autopsy is planned for Saturday morning.

Illinois State Police investigators also reported to the scene. A call to a State Police supervisor wasn't returned immediately.

The agency will be handling the investigation, as required by state statute for any fatal shooting involving a law-enforcement officer.

"Intentionally, we are letting the State Police do their work," Huston said. "Obviously, we're not going to step on anyone's toes."

As of about 2:30 p.m., at least 10 vehicles were parked in front of the beige, one-story residence. It's located about three miles east of Mackinaw and east of Lilly Road, on the north side of Route 9.

Yellow crime-scene tape encircled the residence. A red barn is located on the property.

The incident is the third in the past eight months in the Tri-County Area in which an officer-involved shooting has resulted in a civilian death.

In September in Peoria, Eddie Russell Jr., 25, was shot and killed by city police after after a two-hour standoff. He had allegedly robbed a nearby bank hours before and was shot after he emerged from the house and raised his arm while holding a weapon.

After a lengthy State Police investigation, Peoria County State's Attorney Jerry Brady found the officers had acted properly.

On Feb. 1, Daniel El, 32, was shot and killed by Peoria officers after he fled from a traffic stop and then ran from officers. That case remains under investigation.

Russell suffered from mental-health issues, his family and police stated.
