MEMPHIS, Tenn. (AP) — Documents released Tuesday provided a scathing account of what authorities called the "blatantly unprofessional" conduct of five officers involved in the fatal police beating of Tyre Nichols during a traffic stop last month — including new revelations about how one officer took and shared pictures of the bloodied victim.

The officer, Demetrius Haley, stood over Nichols as he lay propped against a police car and took photographs, which Haley sent to other officers and a female acquaintance, according to documents released by the Tennessee Peace Officers Standards and Training Commission.

"Your on-duty conduct was unjustly, blatantly unprofessional and unbecoming for a sworn public servant," the Memphis Police Department wrote in requesting that Haley and the other officers be decertified.

Haley's lawyer declined to comment, and lawyers for the other four officers either declined to comment or did not respond to requests from The Associated Press.

The five officers — Haley, Desmond Mills Jr, Tadarrius Bean, Justin Smith and Emmitt Martin III — have all been fired and charged with second-degree murder. The new documents offer the most detailed account to date of each officer's actions.

Another officer has also been fired and a seventh has been relieved of duty in connection with the latest police killing to prompt angry nationwide protests and an intense public conversation about how police officers treat Black residents.

As many as 13 Memphis officers could end up being disciplined, officials said Tuesday.

The newly released documents are part of a request by the Memphis Police Department that the five officers who have been charged with murder be decertified and prohibited from working in law enforcement again. Memphis Police Chief Cerelyn "CJ" Davis signed each of the five requests to decertify the officers.
