CHICAGO (KRON) — Police in northern Illinois say a massive manhunt with dogs and helicopters is underway for three suspects shot and killed an officer Tuesday morning.
Lake County Undersheriff Raymond Rose says the officer was pursuing people described as suspicious when he was shot and killed in Fox Lake, 55 miles north of Chicago.
According to police the officer was on routine and radioed just before 8:00 a.m. that he was going to check on suspicious activity.
He then radioed that he was in a “foot pursuit” but communication was lost after that, Covelli said.
Other units responded and found him in a marshy area in the city of Fox Lake.
The officer was stripped of his gun and other equipment police officials said.
Police say they are looking for one black male and two white males.
“Grant Community High School is currently in a lockdown at the request of the Fox Lake Police Department,” “A police matter is occurring in the community and for the safety of our students and staff they have requested we remain locked down.”
Metra’s Milwaukee District North Line has also been shut down because of the search, the agency said.
