Sparks police are investigating a series of 911 calls that led to a car accident last night. Police say 22 year old William Thayer started calling 911 around 9:30 p.m. and told dispatchers someone was shooting at him in the area of 4th Street and McCarran Boulevard. However, dispatchers say the calls were coming from the D’Andrea area. Police then got a call about an accident at Vista Boulevard and Los Altos Parkway. When they arrived at the scene a man told them his truck had been hit by another driver, who police identified as Thayer. Police followed Thayer to Vista Boulevard where he crashed again and was arrested after a short foot chase. He faces multiple charges.
