SAN ANTONIO – A Crime Stoppers tip led to the arrest of 23-year-old Cristan Aguero Thursday evening.
Aguero was wanted on a charge of assault against the elderly from an incident May 14 at a Walmart in the 4300 block of Thousand Oaks.
Surveillance video showed Aguero talking on the phone and appearing agitated as he walked around.
At one point, Aguero threw the phone on the ground.
A 67-year-old man who was outside of the Walmart asked Aguero if he was OK and Aguero punched him without provocation, police said. The victim fell to the ground unconscious and suffered internal injuries from the fall, including a ruptured spleen.
Because the attack was against the elderly, the assault charge was upgraded to a first-degree felony.
As Aguero was led from Public Safety Headquarters to the Bexar County Magistrate's Office to officially be charged with the crime, he apologized for his actions, saying he never intended to hurt the victim.
Aguero was arrested on the city's Northeast Side Thursday afternoon without incident. He was currently on parole for another crime.
The victim also lost his dog because of the attack. He left his dog in his car in the parking lot that morning and wasn't able to let anyone know of the dog's whereabouts until after he was at the hospital. The dog died from heat exhaustion.
