SPRING, Texas (AP) — Students return to classes at a high school in a northern Houston suburb five days after a deadly knife attack closed it.

Classes resume Monday at Spring High School in Spring, where the Wednesday knifing killed one student and wounded three others.

Luis Alonzo Alfaro, a 17-year-old student, has been charged with murder in the stabbing that left 17-year-old Joshua Devon Broussard dead on the floor of a school corridor.

Investigators say Alfaro told them the fight began when he bumped a different youth in the school cafeteria.

But Harris County Sheriff's Office investigators said Thursday that gang rivalry appears to be the motive in the slaying at Spring High School in Spring.

Alfaro is jailed on $150,000 bond.
