SAN DIEGO (KGTV) - 688 Patrick Henry High School students called in sick today after a threatening message was discovered on campus, according to the San Diego Unified School District.
A message reading "I'm going to shoot up the school on 5/12/17 F ... PHHS" was found on the wall of a racquetball court on campus Wednesday. School officials believe the message was written at about 8:40 a.m. and brought to the attention of officials at about 9 a.m. the same day.
Staff went out and documented the message before removing it from the court. San Diego Police was also contacted and have been on campus for the last two days providing support and investigating the incident.
Sari Winet, communications director at San Diego Unified School District, said Thursday there's no credible threat to the school.
A letter to parents from PHHS principal Listy Gillingham said the message's author was identified Thursday.
"The student is very remorseful and did it as a joke, they were not angry at the school in any way. The student realized later in the day that they made a serious mistake, but was too afraid to come forward," Gillingham's letter read. "As with any threat of this nature, we will be following all protocols involved to make sure the student understands the seriousness of this crime both legally and through the school."
No comment was given regarding disciplinary actions against the student.
"I appreciate the patience and trust you put in the school to solve this. I was proud of every student who emailed me and who came into our office with a report to help us," Gillingham added.
School activities Thursday night were not impacted by the incident.
