An 11-year-old also was involved but is too young to be charged with murder, police said. Detectives are working with prosecutors and state social workers "to determine what charges he may face and whether he can be held on those charges," according to the statement.
The 13-year-old was expected to be booked into juvenile detention. The statement said detectives were searching for the other boys.
Scott Dwight Habermehl, 63, was riding to his job at Sandia National Laboratories early in the morning last May when he was hit by a car that swerved into the bike lane, according to police.
The crash was recorded from inside the car and circulated on social media. In the recording, a voice believed to be the 13-year-old can be heard saying he is about to hit the bicyclist, according to law enforcement. The car appears to accelerate and a voice believed to be the 15-year-old's says, “Just bump him, brah.”
The driver asks, “Like bump him?”
A passenger says, “Yeah, just bump him. Go like…15…20.”
Loud sounds can then be heard in the recording, including “metal flexing,” according to law enforcement.
