A teenager accused of killing an Uber driver on January 21 was sentenced to 45 years in prison on Thursday, Tarrant County Criminal District Attorney Phil Sorrells announced in a news release.

Zak Marshall, 17, pleaded guilty to the 2021 murder of 31-year-old Ryan Munsie Graham.

Graham, a mother of three, was employed by Uber Eats and delivering food to an apartment complex in Haltom City on January 23, 2021, when Marshall fatally stabbed her, the release stated.

Marshall, who stabbed her in the neck and left her in a pool of blood, later admitted that he and an accomplice wanted to steal Graham’s car but couldn’t find the keys, according to the DA.

Both were arrested for murder; Marshall pleaded guilty to a lesser charge.

Marshall was 14 at the time of the murder. He was tried as an adult, while his juvenile accomplice pleaded guilty to aggravated robbery in 2022 and received a seven-year sentence in the Texas Juvenile Justice Department.

“This was a brutal, senseless murder,” said Assistant Criminal District Attorney Rose Anna Salinas in the release.

According to the release, Donna Munsie, Graham’s stepmother, spoke via Zoom at Marshall’s sentencing.

“Ryan did not deserve to have her life taken,” said Munsie, who said she’s tasked daily with explaining to her grandchildren that their mother is gone. “She had such a good heart. Her laughter was infectious. We think about her every day.”

Marshall later addressed the court, apologizing to the family.

“I am sorry for what I’ve done and I think about it a lot. … I’m sorry she was the one who had to experience my anger for things that had nothing to do with her,” he said.

Suzanne Munsie, Graham’s mother, did not hold back in her statement to the court.

“I don’t want to hear about anger,” she said. “You made a choice to go out to try to steal a car. You made a choice … to stab her in the neck with a knife. Who does that? You’ve destroyed everything. … I’m glad they gave you 45 years.”
