NEWS lettering

The 18th Judicial District Critical Response Team has been called in to investigate a deputy-involved shooting that occurred at 9:45 p.m. on Sunday, Oct. 29, 2017 at the employee parking lot entrance of the Arapahoe County Sheriff’s Office headquarters building.

An on-duty deputy exiting the parking lot observed a vehicle backed into the exit gate area. The deputy contacted the driver and observed that he had a gun. Two other deputies arrived almost immediately. When the man turned the gun toward one of them, deputies discharged their weapons to stop the threat. CPR was administered at the scene, without success. No deputies were injured during the incident.

The suspect has been identified as 50-year-old Mark Bidon. Bidon was a deputy at the Arapahoe County Sheriff’s Office from 2000 to 2010, when he resigned.

“This is a difficult day for our entire agency,” said Sheriff Dave Walcher. “Not only are we needing to support our deputies who have been involved in this critical incident, we also want to provide support to those employees who previously worked with the suspect and may be affected by these events.”

Secondary aspects of this case:

In accordance with Arapahoe County Sheriff’s Office policy, the deputies involved have been placed on administrative leave or temporarily assigned to other duties pending the outcome of an administrative review of the incident.

Officer-involved shootings involving our agency are investigated by the 18th Judicial District Critical Response Team. Information about the Critical response Team protocol is available at http://www.arapahoegov.com/1563/Critical-Response-Protocol.
