Dallas County Jail Inmate Dies in Custody – D.A.’s Office Investigates

2012 09 18 18.41.59 scaled

Mr. Mosley was originally incarcerated in the Dallas County jail on November 23, 2018. As of December 4, 2018, for unknown reasons, he was housed in a medical unit. A jailer performed an inmate check at approximately 4:45 p.m. that day and noticed that Mr. Mosley had not eaten his food. The jailer also noticed that Mr. Mosley was unresponsive with his eyes closed.

Jail staff, including a registered nurse, entered the cell. Dallas Fire-Rescue was contacted, and medical personnel appeared at the cell. Mr. Mosley was transported to Parkland Hospital, where he was pronounced deceased at approximately 5:50 p.m. that day.

The Dallas County Sheriff’s Department filed a custodial death report with the Attorney General of Texas regarding the recent death of Devon Alexander Mosley. Mr. Mosley was only 31 years of age at the time of his death. Information in this post was obtained from that report, and we make no allegation of any wrongdoing against anyone. Instead, we are simply providing information.

The custodial death report notes that the investigation of Mr. Mosley’s death will be conducted by the Dallas County District Attorney’s office. It appears that most custodial deaths in Texas are investigated by the Texas Rangers. We are uncertain as to why Dallas County has chosen not to allow the Texas Rangers, a statewide agency, to conduct investigations of its custodial deaths.
