You could not see a bit of a difference between Friday and any other day at Monta Vista High School in Cupertino. But you could hear it.
"I'm worried for the teacher that got the threat," Monta Vista student Angie Inn said. "But I know he's safe with a couple policemen and his family."
She is referring to the teacher named in a bomb threat found Thursday morning on the wall of Lynbrook High School in San Jose. And now we're learning of almost identical spray painted bomb threats left at two other Cupertino schools Thursday -- Cupertino High School and Kennedy Middle School, which is just around the corner from Monta Vista.
"There is more than one graffiti that was done that we discovered yesterday," Lt. Rick Sung said. He says the threats all name the same teacher.
The threat at Lynbrooke High School prompted the shutdown of Monta Vista and nearby Lincoln Elementary School. The high school campus was searched and nothing was found.
Investigators there may be more than one suspect and there's definitely more than one lead.
"Our detectives and deputies have been working around the clock on several different leads," Lt. Sung said. "And in fact we have been getting more calls and tips since last night."
The Santa Clara County Sheriff's Office has additional officers on the Monta Vista campus as well as a couple at the home of the teacher mentioned in those bomb threats.
