Revenge may be motive in school shooting

CENTENNIAL, Colo. (AP) - Investigators in Colorado are looking at whether revenge motivated a teenage gunman to enter his suburban Denver high school armed with a shotgun looking for a specific teacher.

Quick-thinking students at Arapahoe High School alerted the targeted educator, who quickly left the building. Authorities say 18-year-old Karl Pierson critically wounded a 15-year-old student yesterday before killing himself.

Arapahoe County Sheriff Grayson Robinson said Pierson made no attempt to hide his weapon after entering the school from a parking lot and asking for a teacher by name.

Robinson did not elaborate on any possible motive except to say Pierson had had a "confrontation or disagreement" with the teacher.
