'Sophisticated Bomb Making Materials and Instructions' Found in Cherry Valley Man's Home After SWAT Standoff

A Cherry Valley man was jailed on a half million dollars bail Monday, a day after he was arrested following two police standoffs he's been tied to in the area.

49-year-old Bruce Borynack was arrested in Beaumont following the first standoff, which happened in the area of Oak Valley Parkway and Oak View Drive around 10 a.m. Sunday, according to sheriff's Lt. Lisa McConnell.

According to the lieutenant, Borynack was suspected of having bomb making materials at his Cherry Valley home and investigators had obtained a search warrant for the property last week.   What's more, the man was already on bail for another crime, and is facing a trial for possession of explosives and explosive devices, she said.

"Due to the extremely dangerous situation of serving this type of warrant, the Sheriff’s SWAT Team and Hazardous Device Team were enlisted to do the warrant service," McConnell told Banning-Beaumont Patch.

However-- before authorities got a chance to serve that warrant as planned on Sunday, Borynack was seen driving away from his residence with another individual, she said.  Law enforcement officials followed the two, and attempted to pull them over on Oak Valley, near the Chevron gas station.

"They were stopped by Special Enforcement Bureau personnel in the area of Oak Valley Parkway and Oak View Drive in the city of Beaumont," McConnell said.  "There was a brief standoff where both occupants refused to exit their vehicles. Both were eventually detained."

After the two were taken into custody, the sheriff's hazardous device team-- or bomb squad-- checked out the vehicle before it was moved because of Borynack's alleged connection to explosives, according to McConnell.  Following that operation, units then made their way over to the 10000 block of Nancy Avenue in Cherry Valley to continue with the search warrant service.

"Another brief standoff occurred when a male and a female occupant refused to exit the residence," according to McConnell.  "They, too, eventually surrendered and were detained."

Once inside the residence, the sheriff's bomb squad found items described as "sophisticated bomb making materials," according to the lieutenant.

"The [hazardous device team] did locate sophisticated bomb making materials and instructions, inert military ordinance and military ammunition not allowed to be possessed by civilians," she said, adding that since some of the materials fall under federal guidelines, the FBI was called out to assist in the investigation.

According to McConnell, a total of three arrests were made in the case, and the female was eventually released.  Photos and names of the remaining suspects were expected to be released at a later time.  However, jail records indicate that 23-year-old Zephaniah John Borynack and 25-year-old Zackariah William Borynack were also arrested at the Nancy Avenue address on explosive charges.

Riverside County Superior court records indicate that Borynack is currently facing charges in an August 2011 case with 39 felony counts of possession of a destructive device in public, along with a felony count of manufacturing a destructive device.
