When 20-year-old Karlie Tomica got in her car this past January 29 after working a bartending shift at Nikki Beach, she was probably giggling and waving goodbye to her friends. But life for this self-proclaimed "party princess" would be forever changed when she allegedly hit and killed Stefano Riccioletti, who was on the way to his job as executive chef at the Shore Club. While that's bad enough, Tomica is also accused of leaving the scene of the accident. Turns out a Good Samaritan, Jairo Fuentes, who witnessed the accident, chased her down over 20 blocks to her luxury apartment and phoned police while Riccioletti lay dying in the street. Later, toxicology reports found that Tomica had three times the legal limit of alcohol in her blood. She was charged with DUI manslaughter. At a court appearance, Miami-Dade Judge Migna Sanchez-Llorens told Tomica, "In life, you make choices, and you clearly made choices that night. You made choices to drink. It's indicated that your levels were beyond anything ordinary." Maybe Karlie Tomica isn't really a "bad" girl. But she did make "bad" choices. And her predicament serves as a cautionary tale for all of us who think we're fine to drive home after having a few too many.
