TAFT, Calif. – Morgan Alldredge had just finished her oceanography test when a classmate she knows well suddenly walked in the open door to her science class with a shotgun.

"He didn't say anything. He just shot right away," said the 16-year-old junior who was sitting by the doorway as the terrifying events unfolded Thursday morning at Taft Union High School, about 120 miles northwest of Los Angeles.

The round struck a boy in the chest and shoulder. The shooter then quickly pumped the gun Alldredge identified as a Winchester 12-gauge and immediately fired another round at students trying to flee out a back door.
