Authorities have not released a cause of death.

Missouri DOC announces latest death

The department confirmed Armistead's death yesterday, as reported by First Alert 4. Officials said he was in DOC custody from Phelps County but did not immediately provide information about how or when he died.

Earlier deaths at the same facility

The January deaths of two other inmates at Potosi had already put a spotlight on the prison. Local outlet KFMO reported that 65‑year‑old Willie Crenshaw was pronounced dead on Jan. 14 and 48‑year‑old Ronald Halkmon was pronounced dead on Jan. 17. At the time, officials said autopsies were planned and had not yet released causes of death for either man.

Cause of death and autopsies

First Alert 4 reports that the Missouri DOC has not disclosed causes of death for Armistead, Crenshaw or Halkmon. KFMO previously noted that autopsies were expected to clarify the circumstances surrounding the January deaths and could inform any further review by state or local authorities.
