ABC News' Matt Gutman and Benjamin Krolowitz report:
Karlie Tomica is a college student who'd crowned herself on Twitter as "Party Princess, Miami Beach."
Police say the 20-year-old took her title too literally, leaving the swanky Miami Beach club where she worked as a bartender with a blood alcohol content three times over the legal limit, and then speeding in her car into a well-known chef.
The chef, 49-year-old Stefano Riccioletti, was walking to work when he was killed in the Jan. 28 accident, on Collins Avenue, one of Miami Beach's iconic strips. Riccioletti, who was married with three children, was the executive chef at Terraza at Shore Club, an upscale restaurant.
Police initially charged Tomica, 20, with leaving the scene of an accident, but added the DUI manslaughter charge Friday when they got the results of her blood alcohol test. She faces up to 30 years in prison if she's convicted.
