Student arrested for threatening mass shooting at Gaither High School

TAMPA, Florida — The Hillsborough County Sheriff's Office is investigating a threat made by a student at Gaither High School.

On August 12, 2024, at 10:30 a.m., the School Threat Assessment and Response Team responded to Gaither High School and made contact with Larenn Olsson, 15. During an interview, Olsson admitted to investigators that she threatened to shoot up her school via a post on Instagram. She was taken into custody without incident and is facing charges of Written or Electronic Threat to Conduct a Mass Shooting or Act of Terrorism and Unlawful Use of a Two-Way Communications Device.

"Today, on the first day back to school, we faced a concerning situation where a student made a violent threat on social media. I am deeply disappointed that such behavior surfaced on what should have been a positive and safe start to the school year," said Sheriff Chad Chronister. "However, I want to express my sincere gratitude for our detective's swift and decisive actions. Their professionalism and vigilance ensured the situation was handled promptly, keeping our schools and community safe."

This is an ongoing investigation; any further information will come from the Public Affairs Office, according to the Hillsborough County Sheriff's Office.
