Southern California teen says FBI probe followed his home science experiments

A 17-year-old in Irvine says his home science experiments led to a nearly week-long response that included the FBI and hazmat teams, and his family remains unable to return to their home.

Authorities in Irvine responded after a landlord reported suspicious materials at a home in a gated neighborhood. The response involved local fire investigators, FBI personnel, and the National Guard’s Weapons of Mass Destruction Civil Support Team. Officials and a source said materials and writings found at the scene prompted concern, but investigators have not publicly detailed their findings. The 17-year-old resident, identified as Amalvin Fritz, has said he is interested in science, has cooperated with investigators, and has posted home experiments online. Known details: - Law enforcement and emergency teams were called after a landlord discovered materials described as suspicious. - The Orange County Fire Authority, FBI personnel, and the National Guard WMD Civil Support Team assisted at the scene. - Investigators have not publicly released specific findings, and the family has not yet been able to return home. - The teenager, a pre-med student slated to graduate from the University of California, Irvine, says he conducted experiments at a home lab and has cooperated with investigators. Summary: The investigation has kept the family from returning to their home while authorities assess the situation and handle the materials. Officials have not publicly released detailed findings. Undetermined at this time.
