Dallas Cowboys defensive tackle Josh Brent is back behind bars after surrendering to police Thursday morning. Brent was then booked into Dallas' Lew Sterrett Justice Center on Thursday, where he has been denied bond following a second positive drug test for marijuana.
According to court documents, Brent was tested for marijuana on June 19 and on June 25 a positive result from that test was confirmed. (See Dallas County's court notification on Brent's failed drug test here)
This is the second time the Cowboys player has tested positive for the drug since his arrest on an intoxication manslaughter charge.
Brent appeared in court May 24 when questions were raised about whether he'd consumed alcohol based on readings from an ankle monitor he wears as a condition of his bond.
At that time, Brent was ordered by the court to submit to a urinalysis test to insure his compliance with the bond agreement. The results of the test showed Brent tested positive for marijuana use within 30 days of the administering of that test.
Brent is charged with intoxication manslaughter in connection with a Dec. 8, 2012, car crash that killed teammate and best friend Jerry Brown Jr. Police said Brent had a blood-alcohol level twice the legal limit for driving.
Brown was on the Cowboys practice squad and a college teammate of Brent's.
Bond has been denied after this latest incident. Initially Brent was free on a $100,000 bond after being charged in the crash that killed Brown.
Brent's next scheduled hearing was set for July 19.
