Man, 35, chases down two 17-year-olds who allegedly stole his car. Teens end up shot after struggle, one of them fatally.

After a 35-year-old Illinois man located and chased down two 17-year-old males who allegedly stole his car days before, the teens ended up shot after a physical altercation early Sunday — one of them fatally, investigators told the Chicago Tribune.

The 35-year-old Round Lake Beach man reported his 2012 Chevrolet sedan stolen from his home Dec. 30 and spotted the black vehicle in Volo about 3 a.m. Sunday, Sgt. Chris Covelli of the Lake County sheriff's office told the paper.

Covelli told the Tribune that detectives were trying to figure out if the man located his car by coincidence, if he had a tracking system onboard, or if he'd left electronics in the vehicle he could trace. Volo is about 15 minutes southwest of Round Lake Beach.

The Carol Stream teens were spotted near Route 12 and Route 120, and the owner pursued them in another vehicle, the paper said. The teens made it about a mile before running out of gas in a desolate, sparsely populated area, the Tribune reported, adding that the car owner confronted the teens in a deserted parking lot. Carol Stream is about 55 minutes west of Chicago and about 55 minutes south of Volo.
