Gerald Walker, a Air Force veteran, served with the Garland Police Department for 17 years. He had previously served with the Farmers Branch and Grapevine Police Departments for a total of five years. While conducting a routine traffic stop, he was shot in the chest and died of his injuries later that night.

Walker was known for his dry sense of humor but was quick to laugh. As a senior officer, he was often sought out for advice. He chose to work late nights because that was where the action was.

Gerald was a person who lived a life of service from the time he was a teenager until his death. He died protecting the people of the city that he loved.
