VENTURA, Calif. (AP) — Southern California prosecutors will retry a 17-year-old boy on a murder charge in the slaying of a gay classmate three years ago, but have dropped allegations the crime was motivated by hate.The decision was announced Wednesday in Ventura County Superior Court and Judge Charles Campbell set a Nov. 21 trial date for defendant Brandon McInerney.Campbell declared a mistrial last month after jurors couldn't agree on the degree of McInerney's guilt for killing 15-year-old Larry King.McInerney was 14 at the time of the shooting in a classroom at E.O. Green Junior High School in Oxnard. Deputy District Attorney Maeve Fox says McInerney will be tried again as an adult.McInerney's lawyers have argued that juvenile court would be the best venue.
