Chaos erupted in the quiet town of Yucaipa after multiple explosions shook residents in what has now been revealed as alleged stalking and unlawful explosive activities. According to a press release from the San Bernardino County Sheriff-Coroner Department, authorities responded to reports of an explosion and subsequent fire in the area of 4th Street and Avenue E on December 18th.
Investigators, including the Yucaipa Fire Department and CAL FIRE, were on the scene to unravel the mysterious series of events that led to the discovery of multiple explosions in the area over the previous week. The assistance of specialized canines like accelerant K9 Mocha, and explosive K9 Flash were called in to conduct a post-blast examination. The investigation, which encompassed destructive device remnants and video evidence, led to the identification of 45-year-old Ryan Karl Silva as a prime suspect, as well as Tiffany Marhoun, 40, after further examination at Silva's residence.
Law enforcement's diligent pursuit of clues in this case took a drastic turn on December 21 when officials served a search warrant at Silva's home. In a statement to Nixle, investigators uncovered not just links to the explosions but also suspected methamphetamine and an unserialized gun, adding layers to the already complex situation. While Silva faces charges for stalking and unlawful possession of an explosive device, Marhoun was arrested on a separate drug possession charge.
Ryan Silva now sits behind bars with bail set at $500,000, and Tiffany Marhoun has been booked at Central Detention Center in San Bernardino. With an ongoing investigation, the sheriff's department is urging anyone with more information to step forward and potentially assist in piecing together this explosive puzzle. Residents, particularly witnesses or those with knowledge of Silva's activities leading up to the arrests, can contact Deputy Arden of the Yucaipa Station or CAL FIRE Officer Milloy, numbers which were released in the Yucaipa Police Department report.
