Teens Arrested for Rock-Throwing Murder Took 'Memento' Photo of Victim's Car

Three Colorado teenagers have been arrested and charged with murder in a series of rock attacks on vehicles across Jefferson and Boulder counties that left 20-year-old Alexa Bartell dead last week. The suspects allegedly threw rocks at five different vehicles, including Bartell's, killing the 20-year-old woman just before 11 p.m. as she was driving while talking on the phone with her friend. The suspects took a photo of Bartell's damaged car as a "memento." They are each facing charges of first-degree murder and extreme indifference.
