Videos show police fatally shooting Anthony Alvarez in Chicago

A 22-year-old Chicago man was running from police, had his back turned, and appeared to have a gun in his hand when he was fatally shot by police last month, according to videos released by the city's police oversight agency on Wednesday.

In body camera video, officers can be heard ordering Anthony Alvarez to drop a gun as he attempted to run away on March 31. Video from a doorbell camera at a nearby home appears to show Alvarez with a gun in his right hand. An officer fires his weapon several times, killing Alvarez.  The officers at the scene call for backup and begin administering first aid to Alvarez. One officer says, "Stay with me, man. Stay with me."
