San Diego County District Attorney Bonnie Dumanis announced Aug. 4 that William John Cooper has pleaded guilty in the United Kingdom to three counts of harassment and one count of violating a restraining order in connection with a bomb threat he made to La Jolla Country Day School by phone and harassing emails he sent in February of this year.

Sentencing in Britain is set for Tuesday, Sept. 1.

Cooper is also charged by the San Diego County District Attorney’s Office with making a bomb threat and phone harassment.

A warrant was issued for Cooper’s arrest by county law enforcement on May 27. Because he carried out his threats while residing in England, officials there are able to charge Cooper and carry out the prosecution for the crimes he committed against individuals in San Diego.

Cooper was arrested by Hampshire Constabulary on June 26 at his home in Southampton, Hampshire, England, where authorities seized his computers and phone. He posted bail and is due back in the West Hampshire Remand Court.

Even though Cooper is being prosecuted in England, he can and will be prosecuted in San Diego County, if he returns to the United States. At this time, there are no plans to extradite Cooper to San Diego unless he is already on U.S. soil.
