A fourth athlete from San Dieguito High School pleaded guilty Monday to assault charges arising from a series of North County attacks.
The 17-year-old senior from La Costa pleaded guilty to felony battery with serious bodily injury in an attack June 25 on a Leucadia family in their driveway. Charges from a May 30 party in Olivenhain were dropped.
Superior Court Judge Norbert Ehrenfreund, sitting in Juvenile Court, set sentencing for the youth, a star running back on the football team, for Jan. 7.
The youth's father said his son has learned that "throwing a punch and being a big shot is not worth" being arrested and going to court.
