All three 18-year-olds are suspected of throwing rocks out of a car.
Three suspects have been arrested for allegedly throwing rocks toward at least seven cars on Colorado roads last week, authorities said. The last of the seven incidents claimed the life of 20-year-old driver Alexa Bartell.
The suspects, all 18-year-old men, were taken into custody at their homes in Arvada overnight and are all facing charges of first-degree murder, with extreme indifference, the Jefferson County Sheriff’s Office announced.
