It’s been nearly a year since an unarmed Texas man was shot by a Mesa police officer, and now his parents have filed a wrongful-death lawsuit against the city and the former officer involved.

Norma and Grady Shaver’s lawsuit was filed Tuesday in Maricopa County Superior Court and seeks unspecified damages. The couple’s son, Daniel Shaver, was killed outside his Mesa hotel room last January after police responded to a report of someone pointing a gun out a window.

Shaver reportedly begged police not to shoot him moments before Officer Philip Brailsford opened fire.

Brailsford was fired by the police department. He has pleaded not guilty to a charge of second-degree murder in Shaver's death and is facing trial. Shaver's widow filed a $35 million notice of claim against Mesa over the shooting.
