Mendiver Sells Explosive Devices Via Instagram

According to court documents, Mendiver used an Instagram account to sell explosives and explosive materials and worked closely with a Bakersfield high school student to fill transactions and send explosives in the mail to residents outside California.

On June 1, a search warrant executed at Mendiver’s residence in Bakersfield resulted in the seizure of approximately 500 pounds of explosives and explosive materials. Agents seized another 500 pounds of explosives and explosive materials from the juvenile’s residence. At both residences, agents found other items used to make explosives.

In one Instagram message to the juvenile, Mendiver sent a photo of titanium salute, an explosive device, followed by two videos he took of homemade explosive devices that he had made.

Bakersfield police assisted the FBI in the investigation. Assistant U.S. Attorney Karen A. Escobar is prosecuting the case.
