Administrators at the American Heritage schools — Heritage K-8 Charter, Escondido Charter High School, Heritage Digital Academy Middle School and Heritage Digital Academy High School — announced the single-day shutdowns on their joint website, saying they wanted “students and staff to be safe.”
Dennis Snyder, executive director of the schools, described the threat to reporters.
“(Staffers) saw posted that … at 10:30 (a.m.) `Escondido Charter High School is going to be shot up; `I’m going to kill myself,’ or `commit suicide,’ along those lines, (and) `You’ll see me on the news,”’ Snyder said.
On Thursday afternoon, several callers alerted police to the menacing statements, which were posted on a social-media website, Lt. Neal Griffin said. Investigators notified the schools and were treating the hostile statements as a credible threat.
There were no arrests in the case as of late this morning, the lieutenant said.
School officials said classes would resume Tuesday, following the three- day Martin Luther King Jr. holiday weekend.
The four campuses in the 1800 block of East Valley Parkway have a combined enrollment of about 1,700.
Snyder, a teacher and former football coach in the Escondido Union High School District, founded the schools in 1996.
