"Teens' Fatal Rock-Throwing Attack: Photo and Memento Taken as 'Blood Brothers' Bond"

Three 18-year-old teens have been arrested on suspicion of murder after allegedly throwing a large rock that killed a Colorado motorist. The suspects took a photo of the scene and pledged a "blood brothers" oath to keep quiet about the crime. Investigators found biological matter throughout the victim's car and a large "river rock" on the side of the road, stained with blood. The suspects have been ordered to be held without bail. The motive for the deadly rock throw is still unknown.
