DALLAS — A judge on Friday denied a request by Dallas County prosecutors to put Cowboys defensive tackle Josh Brent in jail until his trial on an intoxication manslaughter charge.At a bail revocation hearing, prosecutors called witnesses who testified that Brent had repeatedly missed required times when his ankle monitor, which tests for alcohol consumption, was to be downloaded for information.He also missed two appointments with a county officer.As a condition of his $100,000 bail, Brent is required to wear the alcohol-detection monitor and meet regularly with the officer.Brent was charged in the fatal car crash Dec. 8 in Irving that killed Jerry Brown, a Cowboys practice squad player, college teammate and friend. Brent was driving with a blood-alcohol content more than twice the legal limit, police have said.Instead of revoking his bail, state District Judge Robert Burns ordered a second form of monitoring that takes breath samples and ordered Brent to provide a urine sample. Burns said he would not increase Brent’s bail.Brent’s ankle monitor detected alcohol four times in February and March, but both sides agreed Friday that those instances were most likely caused by the presence of alcohol in the air or near Brent — not by drinking.His attorneys said they didn’t know how the alcohol positives occurred but suggested in court that they could have been triggered by things as benign as mouthwash or hand sanitizer.Brent sat silently throughout the nearly hour-long hearing, though at times he tapped one of his attorneys, George Milner, on the shoulder and whispered in his ear.He did not testify and declined to answer questions outside court.Heath Harris, the Dallas County first assistant district attorney, said authorities wanted to be certain that Brent wasn’t drinking or doing anything to violate his probation.“Even though ... we can’t prove beyond a reasonable doubt that he was drinking, we can’t prove that he was not drinking,” Harris said. “That’s the biggest problem.”Milner accused prosecutors of making a show of otherwise ordinary issues, many of which are from earlier this year, because of Brent’s notoriety as a Cowboys player. His career is on hold pending the outcome of this case.“I think we’ve unequivocally established the fact that the district attorney’s office is treating Mr. Brent differently because of the helmet that he wears,” Milner told reporters outside court. “There’s no disputing that now. Everybody down here knew it. Now it’s out in uncontradicted, sworn testimony.”Harris denied that.“This guy is a repeat alcohol offender that killed someone in our county,” he said. “We take offense to that.”Irving police have said that on the night of the crash, Brent’s Illinois driver’s license was suspended because he had pleaded guilty three years earlier to a misdemeanor charge of driving under the influence. Brent and Brown both played college football at the University of Illinois.The sentence range in the Dallas County case is probation to 20 years in prison.
