Seven to eight shots were fired, forcing the lockdown of Double
Diamond Elementary School across the street, police said.

Students were released earlier for parent-teacher conferences, and only several teachers and parents were at the school at the time. They were not allowed to leave until police confirmed the suspect had fled.

The boys were released after treatment for injuries. One or both of the victims were Damonte Ranch High School students, said Washoe County School District spokesman Steve Mulvenon.

The suspect surrendered at police headquarters about six hours after the shooting.

The suspect was accompanied by "some adult in his life he trusted to help make the right decision," said police Lt. Robbie Nuttall.

In Sparks, a lockdown of Dilworth Middle School was ordered Thursday afternoon after there was a report of a man walking by
with a rifle.

The weapon, which turned out to be a BB gun, was later found near the school, police said.

Joseph Matcham, 19, of Reno, was arrested on suspicion of possession of a dangerous weapon on school grounds and brandishing a weapon.

The incident apparently stemmed over a fight between juveniles,
police said.

The suspect's arrest Thursday at an Interstate 80 interchange in Reno briefly shut down the interstate's westbound lanes.
