A man who was allegedly found with more than 900 pounds of explosive material in his Pacifica home in March was ordered to stand trial in San Mateo County Superior Court on Thursday.
Marc Ormando, 47, of Pacifica, was arrested March 5 after allegedly supplying explosives to dealers in San Francisco.
He pleaded not guilty in San Mateo Superior Court to five felony charges involving possession and sale of explosives and child endangerment.
On Thursday he was ordered to answer to all charges, according to the San Mateo County District Attorney’s Office.
His arrest followed a multi-agency months-long undercover investigation of explosives supplied to people dealing in San Francisco.
San Pablo resident Sean Gunther, 37, was also arrested as part of the investigation led by San Francisco police, the FBI, U.S. Marshals and the Marin County Major Crimes Task Force.
In a March 5 search at Ormando’s home on Seaside Drive in Pacifica, authorities found 938 pounds of explosives, 732 barrel bombs and 44 pounds of “black powder,” or gunpowder, according to the San Mateo County District Attorney’s Office.
Authorities also found nine guns and eight rifles in the house, which are believed to have been legally purchased, according to prosecutors.
Ormando’s child endangerment charge stems from allegedly having his 10- and 7-year-old children at home with the explosives when police searched his residence, prosecutors said.
Gunther’s San Pablo home was also searched and more explosives and narcotics were allegedly found there, according to police.
Both Ormando and Gunther were initially charged in San Francisco Superior Court on various possession and sale or transportation of a destructive device charges, according to San Francisco district attorney’s office spokesman Alex Bastian.
Gunther was also charged with possession of methamphetamine.
Both pleaded not guilty in San Francisco Superior Court to the charges.
Ormando’s case was then transferred to San Mateo County, where he was arraigned and remains in custody on $750,000 bail, according to prosecutors.
He will return to court on June 6.
Gunther’s case remains in San Francisco County Superior Court. He is out of custody on reduced bail, according to the San Francisco District Attorney’s Office.
