Police in Texas are searching for a gunman who shot and killed a teenage cancer patient in what they say was likely an attempted robbery.

MyFoxDFW.com reported that 15-year-old Ryan Lara was moving his parents’ car from the street into their garage when he was shot Saturday night.

The Dallas Morning News reported that the teen’s family members heard gunshots and ran out of the house. They said they saw a gray or silver sedan fleeing the scene. A member of Lara’s family fired at the car but it was unclear if they hit the car.

Lara, a seventh grader, had been battling Lymphoma, according to the Dallas Morning News. He died from his injuries at a hospital.

A $5,000 reward is being offered for information about anyone involved in the incident.
