A suspect in the shooting death of two Hattiesburg, Mississippi, police officers has died after being found unresponsive in his cell.
Marvin Banks, 29, did not respond to CPR and was rushed to a hospital, where he was pronounced dead on the evening of Dec. 11.
Banks was charged with two counts of capital murder in the May deaths of officers Benjamin Deen, 34, and Liquori Tate, 24, during a traffic stop. He also faced counts of grand theft auto and felon in possession of a firearm, reported KTLA.
Three other suspects in the murders have been arrested and charged. Banks is believed to have been the shooter that claimed the lives of the officers, reported NBC News.
Banks’s mother, Mary Smith, previously said she believed he was guilty.
"Yeah, he did it," Smith said, according to NBC News. "I don't know [why]. He's out of his mind. He was out of his mind. He wasn't the same Marvin."
An autopsy will be performed to conclude cause of death. Banks was in an isolation cell when he was found, and the sheriff’s office would not divulge the last time he had contact with another person, NBC News reported.
