Prosecutors say on March 11, Kirby was driving drunk and at a high speed on Jamboree Road, when he lost control of his Porsche and clipped Charles "Mask" Lewis, Jr.'s Ferrari, causing it to smash into a light pole and break in half.
Lewis, who co-founded the clothing line Tapout, died at the scene. His girlfriend was ejected from the car and was seriously injured.
During the preliminary hearing, a police officer testified that Kirby, who has two prior convictions for DUI, admitted to driving too fast at the time of the Crash. Newport Beach Officer Todd Hughes testified that Kirby said he sped up to the Ferrari so his date could get a closer look at the car.
Prosecutors say Kirby abandoned the scene after the accident. They are asking for a sentence of at least 18 years in prison.
