More investigation needed in fatal Cowboys crash

Brent is free on bond after the Saturday morning accident that killed practice squad player Jerry Brown. Police from Irving, who say Brent was driving drunk, met with prosecutors from the Dallas County district attorney's office to discuss the case.

"They talked about the case and where we are in the investigation," police spokesman John Argumaniz said in an email. "They also discussed things the DA would need to file the case."

Prosecutors hope to present a case to the grand jury this month, said Heath Harris, the first assistant Dallas County district attorney. He said a typical involuntary manslaughter case includes a reconstruction of the accident scene and an examination of restaurant or bar receipts.

Irving police said they were also still waiting on results from a blood-alcohol test for Brent. Harris said he expected a few more weeks of investigation before prosecutors get the case.

An intoxication manslaughter charge carries a maximum sentence of 20 years in prison, but a defendant with no prior felony convictions in any state is eligible for probation, Harris said. Brent pleaded guilty three years ago to driving under the influence — a misdemeanor — while he was playing at Illinois. In the Illinois case, Brent was sentenced to 60 days in jail and two years of probation, according to court records.

A misdemeanor drunken-driving charge wouldn't stop a defendant from getting probation on an intoxication manslaughter conviction, Harris said.

"We haven't made any conclusions on this particular case, because we don't have all the facts," he said.
