Boy in New Mexico school shooting took gun from home, police say

(Reuters) - A 12-year-old boy who wounded two students when he opened fire with a shotgun at a New Mexico middle school took the firearm from his home, modified it and planned the attack in advance, police said on Wednesday.

Investigators were also continuing to look into the possibility that the boy, who has not been publicly identified, warned some friends before carrying out the attack on Tuesday at Berrendo Middle School in Roswell, police said.
