Polo Tycoon's Story Wasn't Credible, Juror in DUI Manslaughter Case Says

When attorneys from both sides had their last chance to appeal to jurors in Thursday's closing arguments, they battled about the events of the night of the accident, focusing on how much Goodman had to drink.

"The defendant was impaired, the defendant was speeding, the defendant ran a stop sign, the defendant probably unintentionally had too much to drink that night," prosecutor Sherri Collins said in her closing arguments. "And when the crash happened, did he go around and look at the front of the car to see what he hit or to the canal that was three feet away? No, he headed south.

"He didn't do any of the things that are required by law and, ladies and gentlemen, there is no excuse for that," she said.

When Goodman took the stand, he denied drinking powerful cocktails known as Irish car bombs and mind erasers, which defense attorney Black reiterated in his closing arguments.

"There's no doubt this case is a tragedy, that a young man lost his life," Black said. "This is a sad thing. We all recognize that, but we're not here to compound that tragedy with another one. This is a horrible accident, but this is not a crime."

Goodman has already settled a civil suit over the crash after adopting his 42-year-old girlfriend to help protect his estate.
