“Hemet High will be shot up on 2-28 by a sophomore girl[…] the first on my list is Dr. Shaw[…] Don’t be in my way,” the message scrawled on a bathroom tile read.

“I thought like somebody was just trying to be dumb, make a joke about the school shooting that happened in Florida[…] I don’t think it’s a very funny thing to do,” Hemet High student Michael Barsz told CBS2 News.

Administrators and deputies with the Riverside County Sheriff’s Dept. immediately began investigating the threat and ultimately determined it wasn’t credible. Still, they alerted parents, telling them there will be more law enforcement on campus Wednesday.

“They’re really good about going off and having security at the gates, having teachers up front greeting the students every day. So, that helps a lot,” said parent Melanie Lee.

“It makes me feel more safe because I know there’s going to be more security,” said student Calistra Hawkins.

A social media post raised concerns at nearby Tahquitz High School Monday, though no problems were reported there.

The school’s principal was called out in the message, prompting her response.

“Being directly mentioned is, of course, unsettling. However, my focus is to ensure the safety of my students and staff,” Dr. Emily Shaw said in a statement.
