Former Texas A&M football player Thomas Linze Johnson killed a jogger in a Dallas park with a “large-edged weapon” out of rage on Monday morning.

Former Texas A&M wide receiver Thomas Linze Johnson admitted to killing a jogger in a Dallas park with a “large-edged weapon” out of rage on Monday morning, Dallas police announced.

“It appears Mr. Johnson picked this victim at random. Absolutely random,” Dallas police deputy chief Rob Sherwin toldThe Dallas Morning News. “He just attacked him. … It’s just very unusual. It’s quite shocking.”

Johnson is now in Dallas County Jail, and is being held without bond. He will be charged with murder, according to police.

The victim has not been identified, but police say it was a white male between the age of 25 and 35. The body was discovered early Monday morning and was taken to a local hospital, where he later died.

According to police, Johnson walked to a nearby equestrian center and called 911 before turning himself in.

A cyclist who witnessed the attack recounted the following to Dallas’ NBC affiliate:

“As I get closer and closer I could tell it was a machete and there are repeated blows that are occurring. As I get closer, I could see what’s being hit is a person, laying face down on the ground. It was apparent to me by the time I got close that there was nothing that could be done for the person.”

Johnson last appeared in an Aggies uniform in 2012. In the team’s upset of No. 1 Alabama, he caught three passes from quarterback Johnny Manziel for 22 yards. Johnson would not play in the team’s final three games of the season after taking an unexplained leave of absence. This season would have marked Johnson’s senior year.

Earlier this year, Johnson was arrested on charges of evading arrest, burglary of a habitation and auto theft. The former Aggie reportedly broke into his aunt’s house, and stole her minivan and money.
