[Updated at 4:18 p.m.] Five of the nine people who were shot Tuesday were members of the National Guard, a spokesperson told CNN affiliate KRNV. Two were killed and the other three are being treated in area hospitals.

[Updated at 2:18 p.m.] At least two of the victims killed at a shooting in a Carson City, Nevada, IHOP restaurant were military members who were wearing their uniforms, Chuck Allen with the Nevada Highway Patrol said Tuesday.

Police were still looking into the shooter's possible motive, Allen said, but officials were taking precautions in case military personnel were specifically targeted.

"When you have people in uniform randomly targeted ... we take that seriously," Allen said.

Heightened security measures are in effect in military bases in northern Nevada, affiliate KRNV reported, citing a National Guard spokesperson. The restaurant is located about three miles from Nevada National Guard headquarters, so it would not be unusual for service members to be eating there, the spokesperson added.

[Updated at 2:10 p.m.] Three people were killed and six others were wounded Tuesday in a shooting at a Carson City, Nevada, IHOP restaurant, police said.

Those six victims did not include the shooter, who police said turned a gun on himself.

It "appears its going to be difficult for him to survive," Ken Furlong with the Carson City's Sheriff's Office said about the gunman.

"He was still breathing," he added.

Furlong said that currently the situation appears to be contained to the one strip mall.

"Right now it appears as though there was one shooter," Furlong said. "There does not appear to be safety concerns outside of this area."

Furlong confirmed reports that a semi-automatic weapon was used during the shooting. Some of the victims "appeared to be military folks," he said.

Officials are still investigating any possible motive.
