"The defendant and his fellow officers methodically delivered their own brand of justice not in this courtroom but in the side of a street in southwest Houston," Greenwood said.
Holley's arrest and alleged beating was captured by a security camera at a nearby storage business. In the video, Holley can be seen on the ground, surrounded by at least five officers. Officers appear to kick and hit his head, abdomen and legs.
Jurors were shown photos of injuries Holley said he suffered, including a gash on the right side of his face and a bloodshot right eye.
A community activist released the video, prompting fierce public criticism of the police department. Leaders in Houston's black community said they believed the alleged beating was another example of police brutality against blacks and other minorities in the city, and that the misdemeanor charges against the former officers were not serious enough.
Holley was convicted of burglary in juvenile court in October 2010. He was put on probation, which ended last month.
DeGuerin, said Holley is a gang member -- an allegation Holley denied.
DeGuerin said Blomberg forcefully put his foot on the teen's elbow in order to secure his hands, but that it wasn't a kick. DeGuerin said Blomberg and other officers had been after a gang of possibly armed criminals who had been burglarizing homes during the day. Holley was not armed when he was arrested.
A jury of six, four men and two women, all Caucasians, plus an alternate was chosen over five days as a judge allowed jurors to be individually questioned due to publicity in the case.
If convicted, Blomberg could be sentenced to up to a year in prison.
