Stabbing Suspect Turns Himself Into Dallas Police

DALLAS (CBSDFW.COM) - The suspect accused of stabbing a good Samaritan who was trying to break up a fight along Greenville Avenue turned himself into police less than 24 hours after police released photos of the suspect.

Julian Terrance Martin Jr., 23, turned himself in alongside his attorney.

He was arrested and charged with murder. His bond was set at $250,000.

Police say a fight took place outside Club Kush early Saturday morning between two men.

Terrell Cowherd, who worked as an engineer and had recently moved to Dallas from Houston, stepped to try to break up the fight. An arrest affidavit states Jerry Brown held Cowherd, while Martin stabbed Cowherd to death.

Cowherd was rushed to the hospital but could not be saved. Brown was arrested Saturday morning and charged with murder.

Police then released photos and video of the suspect who actually stabbed the victim.

A family friend recognized the suspect and called Dallas Police.

"They contacted the Dallas Police Department. We were able to identify witnesses at the incident itself. From that we were able to identify Mr. Martin as out suspect. Overnight, we were able to work with his attorney and he turned himself in this afternoon," said Maj. Jeff Cotner, in the Crimes Against Persons office of the Dallas Police Department.

Police are also investigating a third "person of interest" to see what role he may have played in the stabbing.

Cowherd was an associate engineer at Dallas-based Luminant. The company released the following statement regarding his tragic death.

We are extremely saddened by the tragic death this weekend of Luminant employee Terrell Cowherd.

The Dallas Police Department reports Cowherd, age 26, was stabbed to death early Saturday morning while trying to defuse a street altercation in Dallas. Police made one arrest Saturday and on Sunday announced a second arrest of the man they believe did the stabbing and charged him with murder.

Kim Mireles, vice president of environmental services at Luminant, worked with Cowherd and said she was shocked at learning of the death of one of her team members, "He was known as one of the kindest and friendliest people on our staff, always smiling and cordial, " she said. "It is not surprising that Terrell interceded in an altercation to calm the situation. Terrell exuded leadership qualities at a very young age," she added.

"He'll be missed by everyone who knew him, particularly his Luminant family," Mireles said.

Cowherd began what would have been a long and fruitful career with Luminant on November 5, 2012. A graduate in civil engineering from Prairie View A&M University, he came to Luminant after being employed with the Arkansas State Highway and Transportation Department. He was employed with Luminant as an associate engineer for environmental services in the mining department and had the lead for preparing and submitting mine permits to the Railroad Commission of Texas for the company's Monticello and Thermo Mines.

In learning of the death of Cowherd, Luminant chief executive officer Mac McFarland said, "Although we're a company of 4,400 employees doing many different jobs at our plants and mines across the state as we provide electric power for Texas, we're still a family and feel a deep sense of loss from Terrell's death. Our thoughts and prayers are with his family," said McFarland.

"As we all grieve, I also want express my thanks on behalf of all Luminant employees to Chief David Brown and the Dallas Police Department for their fine work in quickly making arrests," added McFarland.
