A $15,000 reward has been offered for information leading to the arrest of the person who beat 37-year-old Ubence Ybarra to death on May 11 near a Walmart in the 9400 block of El Centro Way.
Ybarra's mother, Linda Alvarado, says her son was running a simple errand that ended with his death in the hospital eight days later.
"He went to Walmart at 10:44 in the morning to go buy some shorts," Alvarado said. "By 10:55 in the morning they were calling an ambulance."
Dallsa Police describe the man who may have beaten Ybarra to death as a Hispanic man in his 30s, about 5-feet, 10-inches tall and weighing 180 pounds. Dallas police say he may have driven away in a dark-colored Honda.
"People say they (Ybarra and the man) got out of the car and started fighting," said Alvarado. "We don't know why they were fighting. Was it road rage? We don't know. It's killing us inside not knowing what happened."
Alvarado said she heard there might be cell phone video of the fight.
"I have no information of people filming this with their phone, but I hope there were [people recording it] because we sure could use that information," said Dallas Police Deputy Chief Sherryl Scott.
The reward money for information leading to a conviction is up to $15,000. Oak Farms Dairy added $10,000 to the $5,000 reward from Crime Stoppers.
Ybarra had three children ages four, six and nine.
Alvarado says she had her son's organs donated and feels some peace knowing his kidneys, lungs and liver are helping others live.
Anyone with information about Ybarra's death is asked to call Crime Stoppers at 214-373-TIPS.
