Mayor says "city and police are responsible" after death of 13-year-old dirt bike rider in traffic stop

The mayor of Boynton Beach, Florida, is speaking out about the death of a 13-year old boy on a dirt bike in an attempted traffic stop on Sunday. Police said the boy was driving the dirt bike recklessly when he "went down" on North Federal Highway.

Video obtained by CBS affiliate WPEC shows the boy, Stanley Davis Jr., pulling up at a nearby Chevron gas station shortly before the incident. He goes inside to pay, wearing his helmet. Then he rides away and a police vehicle follows him down the street.

Davis rides out of frame, then circles back, turning north, with the police vehicle close behind.
