Medford police are looking for the driver of a semitruck that knocked over a boy waiting to cross a downtown street and ran over his foot Tuesday morning.

Logan Harper-Vega, 6, was walking north on South Holly Street with his mother, Cecilia Vega, and two younger brothers, one 5 and the other 1, when he was hit, Medford police Lt. Tim Doney said.

The family was waiting at the corner of Holly and West 10th Street when the truck and low-boy or flatbed trailer traveling north on Holly made a right turn to head east on 10th Street. As the trailer swung around toward them, Vega, who was carrying her youngest son, grabbed the 5-year-old to pull him to safety and shouted at Logan to get back.

The trailer hit Logan and knocked him onto his back, then the wheels rolled over his left foot, Doney said. Vega yelled at the truck driver to stop, but the driver, who apparently hadn't seen the family, didn't hear and continued down the street.

Another driver stopped at the intersection saw the accident and drove the family to Providence Medford Medical Center. Officials there called police at about 7:10 a.m. Tuesday, roughly half an hour after the incident, Doney said.

Doney said Logan has multiple broken bones in his foot and likely will need surgery to repair them.

Witnesses said the truck was either red or white and that the trailer had wooden decking. Officers checked businesses and construction sites around downtown yesterday in search of the truck, but couldn't find it.
