Police are looking for suspects in a graffiti incident that took place at Palo Alto High School on Saturday.

The vandal wrote bizarre and sometimes incomprehensible phrases on classroom doors, school pillars and library walls. Statements included “every Jew a 22” and “long live Russia, Iran, and Israel.” Many of the slurs referred to Jews or Israel, and some included transliterations of Hebrew.

Principal Phil Winston described the graffiti as including “racial epithets, comments related to the police and some anti-semitic remarks.”

According to Assistant Principal Jerry Berkson, the vandalism took place between 8 a.m. and 10 a.m. on Saturday morning.

The vandalism was discovered by a Saturday school teacher and was erased within hours.

“[On] Saturday morning, I got a text from the teacher who was at Saturday school, who said that there was graffiti on the walls of the library that stretched around to the English building,” Winston said. “I notified the police and they came out and took a report. I also notified the district maintenance folks and they were out here within about an hour and covered it up.”

The police will take the lead in the investigation, Winston said.

“It’s out of our hands,” Winston said. “It’s a police matter since it’s vandalism.”
