Reward increased to find suspects that killed a 4-year-old in May

BEXAR COUNTY, Texas — Crime Stoppers has increased their reward to $10,000 to find the suspect(s) who shot and killed 4-year-old Mary Ann Marble in May.

The shooting happened on May 8 at the 6700 block of Windsor Hollow Drive at about 7:40 p.m. Officials say two men arrived with AK-47-style guns and shot dozens of times into the home.

Investigators said the 4-year-old, her parents and two other siblings were shot at in what authorities believe was a targeted attack. Mary Ann was the only one that didn’t survive.

Days later BCSO said off-duty law enforcement officer who was walking his dog on the far west side noticed an abandoned Infiniti Q50 that fit the description of the car the suspects fled the area in on and notified law enforcement.

“At this point we don’t know for a fact this is the car that was involved in the shooting,” Sherriff Javier Salazar said on May 11, adding that car came back as stolen from Converse. “But we’re going to be running tests on it to see if we can evidence that anybody was firing a weapon in or near that vehicle.”

Meanwhile, Salazar said in May his agency has received tips and executed “several” search warrants as they work to zero in on the suspects, including at a south-side home. While he said he couldn’t go into details regarding potential new evidence, Salazar said the case “seems to be picking up steam.”

Messages and calls from anonymous tipsters have also helped the investigation, Salazar said, before encouraging those individuals to contact BCSO for follow-up if they think of anything else, no matter how small. Tips can be provided by calling (210) 335-6000 or emailing bcsotips@bexar.org. 

“I think we’re on the trail,” he said. “But I need the tips to continue to come in.”

In the last substantial update provided on June 10, BCSO said it was creating a special task force “comprising of multiple units within the sheriff’s office to investigate and apprehend those responsible.” Asked what the task force entails, a BCSO spokesperson told KENS 5 it involved the agency’s covert and intel units, tech personnel who specialize in cybersecurity, and the fugitive apprehension unit focusing their efforts to solve the case. 

KENS 5 has reached out to BCSO as of Aug. 13 to hear where they are in the investigation. The agency is working on a response.
