9 minutes: New details on Evergreen [CO] school shooting

Jefferson County sheriff’s officials corrected their timeline of the Evergreen High School shooting response Friday, saying deputies arrived three minutes after dispatch, not 2.5 minutes as previously stated. They also revealed the shooter spent nearly three minutes trying unsuccessfully to re-enter the building during the attack.

The detailed timeline, based on 911 dispatch records and school surveillance video, provides the most complete account of the Sept. 10 shooting that critically injured two students. The shooter, 16, fired his first shot at 12:21 p.m., exited the building at 12:23 p.m., spent three minutes trying to force his way back inside through locked doors and was confronted by a deputy at 12:30 p.m.

The shooter, identified as Desmond Holly, died from a self-inflicted gunshot wound.

The first 911 call came in at 12:22 p.m. and lasted approximately 40 seconds as the call-taker gathered information, officials said. The call was transferred to a dispatch queue, and one deputy headed toward the school at 12:23 p.m., before the call was officially dispatched.

The first responding unit was officially dispatched at 12:24 p.m. and arrived on scene at 12:27 p.m.
