Dallas Man Accused of Killing White Rock Jogger Found Incompetent

Father says suspected killer was diagnosed with schizophrenia in 2014

Thomas Johnson, the former Texas A&M football player accused of using a machete to kill a jogger has been found incompetent to stand trial, The Dallas Morning News reports.

According to the paper, Johnson will be sent to North Texas State Hospital for up to 120 days of treatment and evaluation after a Dallas County magistrate on Monday found him incompetent to stand trial based on a report filed by a court-ordered mental health expert.

Dallas police have released new details into the arrest of a man who confessed to hacking a jogger to death Monday morning. Police said Thomas Johnson called 911 and confessed saying, ‘I just committed capital murder.’

Johnson's attorney, Jennifer Balido, told the paper she expects her client will regain competency to stand trial in the future.

In October 2015 Johnson told Dallas police he was angry about his living situation when he picked a jogger at random in a Northeast Dallas park and killed him with a "large-edged weapon."

Runners from across North Texas gathered Monday at White Rock Creek Trail to remember a jogger killed last week while doing what he loved.

An eye-witness to the slaying, identified only as Brandon, said he was cycling along the White Rock Creek Trail at Harry Moss Park when he saw a man hacking another man with what appeared to be a machete.

Police said Johnson admitted to killing a man at the park, later identified as 53-year-old David Stevens, and then leaving the scene to call the police. Police said Johnson borrowed a phone from someone else in the park and called 911 to report a stabbing. He then returned to the scene of the crime where he waited for police and confessed to officers before being placed under arrest.

The wife of a man who was killed at random while running around White Rock Lake two weeks ago took her own life Sunday, authorities said.

Stevens' wife of 25 years, Patti, later took her own life. In the days before her suicide, Patti Stevens told The Dallas Morning News that she felt lost without "the love of my life."

Johnson is a Dallas native who attended Skyline High School and played football for Texas A&M in 2012. He disappeared mid-season and wasn't seen again until he appeared at his family's Dallas home three days later.

A memorial run in 53-year old David Stevens’ name is scheduled for Monday night in Dallas.

In an interview with NBC 5, Johnson's father said his son was diagnosed with schizophrenia in 2014 and that the disease is a "monster."
