Blake A. Russell, 32, the suspect arrested in 2017 for the 2009 murder of Sierra Bouzigard, was found hanging in a mop closet on Thursday, June 21.

An ambulance was called out to the Calcasieu Sheriff's Prison at approximately 5 a.m. after the inmate was found hanging in a mop closet. He was later pronounced dead after being taken to a local hospital.

Russell was arrested in July of 2017 and charged with 2nd-degree murder.

As the investigation continues, his cause of death is unknown, but foul play isn't suspected.
