Brent recently tested positive for marijuana, according to Dallas prosecutors. They asked a judge Thursday to revoke Brent's $100,000 bond and issue a warrant for his arrest, The Associated Press reported.
Brent is accused of driving with a blood-alcohol content more than twice the legal limit at the time of the crash.
Prosecutors said in their motion that Brent failed a urine test taken after a May 24 court hearing in which they had sought for his bond to be revoked due to problems with his alcohol monitoring, according to The Associated Press. While the judge declined to revoke his bond, he did order Brent to provide a urine sample.
Brent is required to wear an alcohol ankle monitor and appear for regular meetings with a county officer. Judge Robert Burns last month ordered a second form of monitoring to take breath samples, and for Brent to provide the sample after the hearing.
The prosecutors' motion said the test results indicate Brent took marijuana within 30 days of the test date and it did not appear the exposure to marijuana was second-hand.
There will be much hand-wringing about this latest turn of events but it's hard to muster any faux outrage about it --Brown's death was tragic. Brent has paid for it and will continue to pay for it. This incident doesn't change any of that. It's a deeply sad situation.
The Cowboys have supported Brent, but Clarence Hill of Fort Worth-Star Telegram reports that the Cowboys have kept Brent on the roster "in name only" because of the wishes of Brown's mother. There was no expectation that Brent would ever play a snap for the team again.
