The defendant is accused of being under the influence of alcohol as he drove at a high rate of speed just north of Laguna Canyon Road. Mr. Caselli is accused of losing control of his car and crashing into a Nissan sport utility vehicle driven by 51-year-old Brook Boynton.

The force of the crash caused the victim's car to spin out of control and roll, ejecting Boynton onto the right shoulder. The victim was killed as a result of his injuries.

Mr. Caselli's vehicle also came to a stop. When contacted by police at the scene, he is accused of displaying objective signs of intoxication including bloodshot and watery eyes, slurred speech, and omitting an odor of alcohol.

Deputy District Attorney Jason Baez of the Homicide Unit is prosecuting this case.
