Arsonist Sentenced Following 2024 Fire at Rimpau Avenue Strip Mall

CORONA, CA – The Corona Fire Department announces the successful sentencing of an arsonist responsible for a dangerous structure fire that occurred on August 11, 2024, in the 1500 block of Rimpau Avenue.

At approximately 7:20 a.m., Corona Fire Department units responded to a working structure fire at a retail strip mall. Upon arrival, crews found heavy smoke and flames showing from the roof of the building. Firefighters initiated an interior attack; however, while crews were inside, a portion of the overhang/soffit collapsed just outside of their point of entry. Fortunately, no firefighters were injured in the incident.

Following a thorough investigation, it was determined that the fire had been intentionally set. On June 3, 2025, Chi Lyu of Palm Desert was sentenced to six years and four months in state prison for violation of Penal Code 451(D) – arson of property. The court also imposed an enhancement under Penal Code 454(A)(2). As part of her sentencing, Lyu was ordered to pay victim restitution and register as an arsonist upon her release.

This outcome is the result of dedicated interagency collaboration. The Corona Fire Department extends its sincere gratitude to the Corona Police Department and the United States Marine Corps Recruiting Station for their assistance and cooperation throughout the investigation.

This case highlights the risks our crews face and the importance of strong partnerships in holding those who threaten public safety accountable.
