The family of De’Von Bailey is demanding an independent investigation into the 19-year-old’s death, saying officers shot him seven times in the back.

Surveillance video obtained from a camera at a nearby apartment building shows Bailey fleeing from two officers before he tumbles to the ground. Colorado Springs police said an officer shot Bailey on Aug. 3 after he reached for a gun, but details haven’t been released because of an ongoing investigation by the El Paso County Sheriff’s Office.

Citing ties between the Police Department and Sheriff’s Office, attorneys for Bailey’s family said maintaining “integrity and impartiality” in such an investigation would be “impossible.”

Among connections between the agencies is former Police Chief Pete Carey, who served with CSPD for more than 30 years before joining EPCSO as its undersheriff.

The attorneys for Bailey’s family also are calling for the release of all body camera footage. They plan a news conference at 11:30 a.m. Tuesday at police headquarters, 705 S. Nevada Ave.

“This evidence cannot be changed and releasing it will in no way compromise the investigation,” organizers for the news conference wrote in a Facebook post.

Friday, the city and police department said the body cam video would be made public as soon as the investigation is complete and turned over to the 4th Judicial District Attorney’s Office.

The Sheriff’s Office said it expects to finish its investigation by the end of this week.
