AUSTIN (October 30, 2009)—The director of the Texas Department of Public Safety has moved to fire State Trooper Arturo Perez, 42, who started his DPS career in Waco, for misconduct including the use of excessive force during an arrest on Oct. 10 on the Dallas North Tollway.

DPS Director Steven McCraw also ordered the Texas Rangers to begin a criminal investigation based on video evidence from the trooper’s in-car camera, the DPS said Friday.

The results of the Rangers’ investigation will be presented to the Dallas County District Attorney’s Office, the DPS said.

Details of the incident were not released Friday and the DPS said the video of the incident will not be made public until the criminal investigation has been completed.

Perez chose to retire before the discharge process was completed, the DPS said.

“Our Troopers receive the best instruction available in the world on use of force issues, and we do not tolerate behavior that so clearly contradicts that training as evident in this instance,” McCraw said.

“Ultimately, it is my obligation to remove from duty any employee who cannot perform consistent with our training, standards and mission to provide public safety.”

Perez worked for the Texas Department of Criminal Justice for almost 16 years before he attended the DPS Academy in 2006.

After graduating, he was stationed in Waco until Feb. 2008, when he transferred to Ennis.

He was transferred in July 2009 to the Dallas North Tollway, the DPS said.
