SIMPSON COUNTY, Miss. (WJTV)- UPDATE: The suspect captured for killing Simpson County Deputy James Blair has been charged with Capital Murder of a Peace Officer by the Mississippi Bureau of Investigation.

The Simpson County deputy died after being shot by Joaquin Stevens Blackwell Friday, according to the Hinds County Sheriff’s Office.

The shooting happened at a mental health center in Mendenhall.

According to Dave Van, the executive director of Regions 8 Health, Blackwell was in the custody of the sheriff’s department. He was brought to Regions 8 Health for evaluation because his family members were concerned about his mental health. After the evaluation, Blackwell grabbed the deceased deputy’s gun while getting in the car. Then, he shot the deputy and left the scene.

Multiple law enforcement agencies arrested Blackwell Saturday, June 13 around 2 p.m. after a two-day manhunt.

According to MBI, this is an ongoing investigation in an effort to identify any other possible subject or subjects that helped Blackwell initially avoid arrest.
