The tragic news comes only one week after Chiefs linebacker Jovan Belcher killed his girlfriend and then committed suicide December 1st.  Irving police spokesman John Argumaniz said the one car accident happened in a Dallas suburb at about 2:20 a.m. Saturday.  Josh Brent was behind the wheel, allegedly speeding when the car hit a curb and flipped at least once.

Police received 911 calls from motorists who saw the car upside-down, but no one had an eye witness account.  When police arrived on the scene, Josh was dragging his teammate from the mangled Mercedes, which was on fire.  Officers quickly put out the small blaze, while others tried to attend to Jerry Brown.

Argumaniz reported that the 25-year old was found unresponsive at the scene and later pronounced dead at the hospital.  Officers conducted a field sobriety test on Josh and he failed it.  Police then arrested him and upgraded his charge to intoxication manslaughter after Jerry Brown was pronounced dead.

Cowboys owner Jerry Jones issued the following statement, "We are deeply saddened by the news of this accident and the passing of Jerry Jones.  At this time, our hearts and prayers and deepest sympathies are with the members of Jerry's family and all of those who knew him and loved him."

Before going to jail, Josh Brent was taken to the hospital for some minor scrapes and a blood drawn alcohol test.  Argumaniz, also indicated that Josh was speeding adding, "I can say investigators are certain they were traveling well above the posted speed limit."

To make matters worse, this is the second time that Josh has been arrested for DUI.  In 2009 he was arrested for DUI and driving with a suspended license on Illinois campus.  He ended up being sentenced to 60 days in jail, two years probation, 200 hours of community service and a $2,000 fine.  As part of his plea deal, prosecutors dropped one count of aggravated DUI/valid license and Josh completed his probation in 2011.
