“The kids loved him,” his sister-in-law Chanda Landsberry said.

She added his life could be summed up by his love of his family, his students and his country.

“To hear that he was trying to stop that is not surprising by any means,” she said.

Police said 150 to 200 officers responded to the shooting, including some from as far as 60 miles away. Students from the middle school and neighboring elementary school were evacuated to the nearby high school, and classes were canceled. The middle school will remain closed for the week.

“As you can imagine, the best description is chaos,” Robinson said. “It’s too early to say whether he was targeting people or going on an indiscriminate shooting spree.”

At the evacuation center, parents comforted their children.

“We came flying down here to get our kids,” said Mike Fiorica, whose nephew attends the school. “You can imagine how parents are feeling. You don’t know if your kid’s OK.”

The shooting happened on the school’s campus and ended outside the school building, according to police.

“I was deeply saddened to learn of the horrific shooting at Sparks Middle School this morning,” Nevada Gov. Brian Sandoval said in a statement extending his thoughts and prayers to those affected.

About 700 students in 7th and 8th grades are enrolled at the school, in a working class neighborhood.
