The incident started about 1:40 a.m. Tuesday, when Englewood District officers responded to a call of a domestic battery in progress, according to a police News Affairs statement.

As the officers approached the home, they saw a man trying to run off, and began chasing him. When an officer ordered the man to stop running, he turned and pulled an object from his pocket that the officer thought was a handgun, police said.

Police shot the man after he “aggressively came at the officer” and did not drop the object as officers ordered, according to the statement, which did not indicate whether a weapon was recovered.

Farmer, of the 6200 block of South Honore Street, was pronounced dead at the scene, according to the medical examiner’s office.

No one else was hurt, and no officers were reported injured, police said.

The Independent Police Review Authority is investigating the incident.
