An off-duty Chicago cop shouted “I’ll kill you” before fatally shooting a man who grabbed for her gun during a struggle last month in Washington Heights on the South Side, video released Thursday shows.

The private surveillance footage, released by the Civilian Office of Police Accountability, initially shows Leevon Smith arguing with a group of people in the 1300 block of West 90th Street just before 1 p.m. on Jan. 18.

The off-duty officer eventually leaves an apartment building, tries to defuse the conflict and urges those involved to “calm down.” The other people take off, but Smith sticks around and talks to the officer for just over a minute.
