SAN ANTONIO (KXAN) – In seconds, the lives of an Austin police officer, a suspect and families changed forever.

Police believe 25-year-old Darrin Andrew Martin shot 37-year-old Austin Police Officer Armando Perez Sunday. Perez returned fire. Martin died.

Police say that before the shooting, a 23-year-old concierge saw Martin on live surveillance video breaking into cars. The concierge left his desk and began chasing the suspect while telling someone to call 9-1-1. The APD officer, who was on regular patrol, saw the chase and called for backup.

“From the reports that I’m getting, that he actually pulled out a gun. He shot a police officer. That’s the [thing] that gets me. I don’t want him to be remembered that way,” said Darrin Martin, Darrin Andrew Martin’s father.

Martin’s father is now trying to reconcile the son he remembers with what happened. He is having trouble making sense of why his son reacted the way he did. He describes his son as a loving person.

“I’ve never seen him that way. I’ve never ever known him to be a person that would pull a gun out and shoot somebody, let alone a police officer,” Martin said.

Still, Martin acknowledges his son’s criminal history. According to DPS criminal records, over the past eight years, Darrin Andrew Martin has been arrested and convicted of three crimes in the San Antonio area. In 2009, he was arrested on a theft charge and received deferred adjudication. In 2010, he was arrested by the San Antonio Police Department for a burglary of habitation charge and sentenced to five years in prison. In 2012, he was charged with unauthorized use of a vehicle. In December 2014, he was released on parole that was set to expire in September 2017.

Martin’s father also has a message for the family of APD Officer Perez.

“I’m sorry. I’m so sorry that this has happened to you and I can’t imagine what you’re going through because I know what I’m going through,” said Martin.

Austin Police Association President Ken Casady told KXAN Monday night the officer is out of the hospital and at home on administrative leave, which is normal after a police shooting.

The Martin family is planning a funeral. Darrin Martin says his son leaves behind a 7-year-old son, along with other family.
