Jury selection began Monday for a former Texas A&M football player who is charged with murdering a Dallas jogger.

Thomas Johnson is accused of killing 53-year-old David Stevens with a machete on the White Rock Trail in October of 2015.

Police said he randomly encountered Stevens on the trail and savagely murdered him. Compounding the tragedy, Stevens' wife of 25-years, Patti, committed suicide two weeks later.

Johnson reportedly called 911 after the attack and confessed. He told police he is schizophrenic and was not taking his medication.

He has been in jail or in a mental health facility since the attack.

His attorney said he is now fit to stand trial after undergoing an extensive psychiatric examination and treatment.
