CITRUS HEIGHTS - The mother of a young man facing multiple charges after explosives found in his home led to a neighborhood evacuation said her son meant no harm to anybody.
"He's a good guy. He's not a terrorist. And I think people will realize that in the end," Kathy Holtz said. "He's just a science geek."
Cale Crase, 25, was arrested Wednesday night after firefighters noticed what was described as "suspicious material" while responding to a kitchen fire in his duplex on Peachtree Avenue.
The FBI, ATF and several local agencies were called in to assess the situation and determined the material was explosive.
After nearby homes were evacuated, the material was safely detonated early Thursday morning. At midday, a commercial HAZMAT crew was still removing buckets and barrels through the garage.
Robert Hernandez, who lives on the other side of the duplex, said he was disturbed by the discovery of explosives so close to his family. "A common wall. Kind of scary," he said.
Video posted on YouTube shows Crase demonstrating an invention he calls The Big Dripper, a device used for "vaping" and marketed as an all-day electronic cigarette.
Citrus Heights police spokesperson Sgt. Mike Wells said the materials found in Crase's home do not appear to be related to any type of drug activity and Crase is not believed to be part of a larger organization.
"We believe this is an isolated incident," Wells said.
Crase is being held in Sacramento County Jail on booking charges of possession of a destructive device, possession of ingredients to make a destructive device and possession of a firearm silencer.
His bail has been set at a $500,000.
