The governor said a staff member received very minor injuries but declined medical care because he wanted to stay and help.
The suspected shooter, whom police have not named, was transferred to an Albuquerque psychiatric hospital following a hearing Tuesday, according to attorney Robert Gorence, who is representing his family. Gorence said the family will release a statement Wednesday.
New Mexico State Police Chief Pete Kassetas said late Tuesday that the shooter used a 22-gauge shotgun. He said they're investigating where he got the gun and have issued search warrants for the boy's home and his bag and locker.
He would only say that the gun was brought to the school concealed, but a witness said the boy pulled it from band instrument case.
On Tuesday night, hundreds of people poured into the Roswell Civic Center for a prayer vigil, including elected officials and law enforcement officers from various agencies. There were many hugs and tears.
"We really need this," Roswell resident Maria Lucero, 35, said of the vigil. "We need to pray for the families of the victims and the little boy that did the shooting. I'm going to pray for them all."
Eighth-grader Odiee Carranza said she was walking to the school gym when the shooter bumped into her as he rushed past. She told him to be careful, and he apologized and continued on. The boy ran to the gym, where he pulled a gun from a band instrument case and fired at the students.
"Then he shot up in the sky, then dropped the gun, and then some teacher grabbed the kid that had the gun," Carranza said.
Carranza described the shooter as a "smart kid and a nice kid."
Student Gabby Vasquez said the boy who was shot "was really nice, got along with everybody."
