The parents of the two boys wounded by a seventh-grader who fatally shot their teacher before turning a semi-automatic handgun on himself said Wednesday they don’t believe their children were targeted in the schoolyard rampage.

Police were interviewing dozens of students who witnessed the shooting as investigators continued to try to unravel the mystery of what motivated the shooter, whom they still have not identified two days after he took his own life on an asphalt basketball court outside Sparks Middle School.

Sparks police Lt. Erick Thomas said investigators still don’t know whether the shooting spree 15 minutes before the start of school Monday morning was random or targeted specific individuals.

But parents of the two 12-year-olds recovering from gunshot wounds said they don’t think they were singled out. One said her son was trying to help the dying teacher, Michael Landsberry, when he was shot in the abdomen with a bullet that exited his back.

“We do not believe he was in any way the target in this shooting,” Jenifer Davis told reporters outside Renown Regional Medical Center, where she said her son Mason was “doing well … in good spirits, although saddened by the loss of his friend, Mr. Landsberry.”

“From what we’ve learned from others at the scene, Mason’s first instinct was to intervene and he did all he could to help Mr. Landsberry,” she said. “It is my understanding that he was trying to help Mr. Landsberry at the time he was shot.”

A parent of the other boy, who was shot in the shoulder, declined to be identified or speak with reporters but said in a statement released by the hospital, “We do not believe our son was a target in this shooting.”

Investigators have confirmed the 12-year-old shooter acted alone, Thomas said, but little else since Landsberry, a 45-year-old math teacher and ex-Marine, was killed while trying to talk the boy into turning over his weapon.

“We’re still investigating how this all happened. We are investigating the motives, all the facts and circumstances that both led up to it and were involved in it,” Thomas said Wednesday.

“It’s a very complicated investigation as far as the number of witnesses and the seriousness of the crime,” he added.

Thomas, the lead investigator in the case that also involves Reno police and Washoe County School District police, said he couldn’t comment on some reports from fellow students that bullying may have played a role in the shooting.

“I can’t release any information on any provocation or anything like that,” he said.

Adding to the mystery surrounding the case is the fact that police have refused to release the shooter’s identity.

The Reno Gazette-Journal published an editorial on its front page Wednesday calling for police to immediately identify the 12-year-old so the circumstances that led to the shooting might be better understood. To do otherwise was a violation of state law, the newspaper said.

Media organizations have filed formal public record requests for the boy’s name.

Sparks City Attorney Chet Adams said Wednesday he believes Nevada law exempts information concerning juveniles from public records laws. But he said that even if it didn’t, police have not completed their investigation or “generated any document that would be considered a ‘record’ subject to dissemination.”

“Moreover, releasing the requested information will hinder the (Police) Department’s ability to thoroughly investigate the incident and draw accurate findings about Monday’s events,” Adams said in a statement.
