VISALIA, Calif. (KSEE / KGPE) – A Tulare County man was sentenced to five years in prison Thursday after unsuspecting charges, including possession of explosives-making materials and elder abuse.

33-year-old Joshua Isgrigg was the caretaker of a 64-year-old family member in a wheelchair, according to the Tulare District Attorney’s Office. On April 5, 2020, he took her car and she crawled to a window for help. This prompted a neighbor to call 911, which resulted in the adult protection services getting involved.

The DA office adds that on June 3, 2020, a search of Isgrigg’s vehicle after it was run over found several plastic jugs containing battery acid, half-crushed hexamine tablets and a 54-point box of ammonium nitrate. A search of his house also found hexamine, ammonia nitrate, 36 pounds of potassium nitrate, 12 pounds of potassium chloride, 3 pounds of potassium chlorate, aluminum powder, 10 pounds of citric acid powder, 2 boxes of hexamine fuel tablets of highly concentrated 60% hydrogen peroxide, and 2 pounds of caustic.

According to the DA office, the laboratory at the Federal Bureau of Investigations in Quantico, Virginia, confirmed that the materials were precursor components in the manufacture of a bomb.

Isgrigg argues against the following crimes:

  • A count of possession of materials used to make explosives
  • A count of elderly abuse under circumstances that could result in serious personal injury
  • A count of abuse by financial elders.
