Police in northern Illinois shot and killed a man suspected of taking photographs of schools while apparently wearing body armor Wednesday morning after a struggle, the Chicago Tribune reported.

Officers responded in Zion around 8:30 a.m. after a man was reportedly spotted taking photos of local schools, according to a statement from the Lake County Major Crime Task Force.

“The suspicious person was located by officers and a foot pursuit ensued,” the statement said. “It appeared the offender was wearing body armor. After the foot pursuit, a struggle with the offender and officers ensued, which resulted in the offender being shot.”

Officers at the scene tried to keep him alive, authorities said, and the man was then taken to a hospital where he was pronounced dead.

A woman interviewed by the Tribune said she heard gunshots around 8:30 a.m. and saw CPR being performed on a man lying on the ground.

Cops said they did not have any other suspects. The identities of the man who was shot and the officer who fired were not immediately released.

Several schools were placed on lockdown after the shooting, but the lockdowns were lifted by early afternoon, the Chicago Sun-Times reported.

A news conference was scheduled for 4 p.m.
