"Newport Beach officers later spotted the Porsche and stopped its passengers, a male and female, who were seen walking away from the vehicle.
Upon further investigation officers determined that the male, Jeffrey David Kirby, a 51-year-old resident of Costa Mesa, Calif., was the driver of the vehicle.
Kirby was arrested for gross vehicular manslaughter and taken to the Newport Beach Police Department. The female passenger, Lynn Marie Nabozny, a 32-year-old resident of Newport Beach, was arrested for public intoxication and released Wednesday morning."
Why was Kirby arrested? He gets gross vehicular manslaughter for racing someone on the road without hitting/touching the other car or another human being?
