Officers responding to a report of a disturbed man in North Park on Monday said they were forced to shoot him.
The incident began shortly before noon when 911 operators got a call from a woman asking for the police to come to a home in the 3400 block of Alabama Street.
Witnesses told detectives that the 56-year-old victim lives in the house with his mother and became agitated after his sister arrived in the morning. Police who went out to the home said the man was outside when they arrived but went in the house soon afterward.
Going inside to check on the man, the officers discovered he had armed himself with a knife and told them that they were going to have to kill him to disarm him.
Police Lt. Kevin Rooney said that the man told the officers they were "going to have to kill him."
The officers said he advanced on them, then they ordered him to stop and drop the weapon. When he continued, one of them fired a single shot.
The man was taken to an area hospital by ambulance but was later pronounced dead.
Officials have yet to identify the officers involved or the dead man.
