Fox news crew record incident. 4/16/2008
CHICAGO Chicago police say an officer shot and killed a 150-pound cougar on the city's North Side.

Police say several residents reporting seeing the cat, which was more than 5-foot long, Tuesday. It was shot dead in an alley.

One witness says the cougar leapt over a 6-foot tall wrought-iron fence.

Authorities say the animal's body will be checked for any markings, chips or tags that would show if it is owned by anyone.

Authorities in suburban Wilmette say they received several calls on Sunday reporting alleged cougar sightings. Police searched, but did not locate the animal.

Confirmed cougar sightings are rare in Illinois.
