A former Texas A&M wide receiver has been charged with murder after allegedly killing a 53-year-old man on a popular Dallas jogging trail Monday morning.

Thomas L. Johnson was arrested Monday after police said he attacked a jogger with a "large-bladed knife," with Johnson reportedly telling 911 responders himself the victim was "laying down with a sword in his head and not moving," according to the Associated Press. A bicyclist told police he had witnessed Johnson striking the victim repeatedly in the head with the blade, according to an arrest affidavit reviewed by the AP.

A five-star recruit out of Dallas's Skyline High School in the class of 2012, Johnson appeared in 10 games for Texas A&M as a true freshman, catching 30 passes for 339 yards. Only two days after recording a pair of receptions in the Aggies' famous 29-24 upset of No. 1 Alabama in November of that season, Johnson mysteriously went missing just before an A&M practice. He was found unharmed on a Dallas street later that week but never returned to A&M.

According to police, Johnson may have been angry over recently losing his housing situation. He was being sought for multiple probation violations and was arrested in 2014 on charges of burglary, auto theft and evading arrest, per the Dallas Morning News.

Johnson reportedly stayed at the scene of the alleged murder, approaching a nearby man to borrow his cell phone, call 911, and allegedly later tell the responding officer "I just committed capital murder."

“It appears Mr. Johnson picked this victim at random. Absolutely random,” Deputy Chief Rob Sherwin told the News. “He just attacked him … It’s just very unusual. It’s quite shocking.”

A Texas A&M statement called the incident "an awful tragedy for all involved" but did not further comment due to "legal proceedings," other than to point out Johnson has not been part of the Aggies program since November 2012.
