A Waukegan police officer shot and killed a man who was advancing on him armed with a knife and a hammer, with a gas can taped to his chest, police said Wednesday.

The incident happened at about 12:45 p.m. Wednesday in the 1000 block of Glen Court.

An officer was responding to a report of a neighborhood dispute, where police were also told that one of the neighbors was attempting to start a chain saw and had gasoline.

When the officer arrived, he found that a wooden fence separating two houses was on fire, police said. The officer retrieved a fire extinguisher from his squad car and, as he walked toward the fire, the armed man with the gas can advanced on him, according to police.

The man refused the officer’s verbal commands to stop, police said, and the officer shot him. He was pronounced dead at the scene.

The man’s identity has not yet been released, pending notification of next of kin and an autopsy. Police said he is a Waukegan man in his 20s.

The officer is a 15-year veteran of the police department. Waukegan Police Chief Keith Zupec has asked the Illinois State Police to investigate the shooting.
