Suspect arrested for bomb threats to school

Riverside, Ca- At approximately 9 a.m., November 21, 2006, Riverside Police East Neighborhood Policing Center Investigations and School Resource Officer Team arrested William Carl DEMLING, 46, at his residence in Lemon Grove (San Diego County) on 13 counts of Threatening A Public Official (71 PC) and False Bomb Report (149.1 PC), following more than a year of investigation.

Beginning in January 2004, an unknown suspect began sending harassing emails to Riverside Unified School District employees. The suspect used many different email accounts, which could not be traced. In August 2005, the tone of emails escalated when the suspect sent his first threatening email to RUSD employees, including a senior administrator, a school principal and a teacher. At that time, the suspect made a specific threat to have a bomb explode at a RUSD school. As the threats and the investigation continued, a School Resource Officer located a possible suspect and developed a search warrant for the many Internet Protocol (IP) addresses used by the unknown suspect.

On August 20, 2006, the NPC East Investigations and SRO Unit served a search warrant at the Lemon Grove residence and four computers were seized as evidence. A Central Investigations Bureau forensic examination of the seized computers found evidence linking the suspect to the email threats.

Investigation also revealed that the suspect, who earned a four-year computer programming degree, met one of the recipient RUSD employees several years ago.

The Riverside Police NPC East Investigations and SRO Unit responded this morning, November 21, to suspect Demling’s residence in Lemon Grove where he was arrested without incident. He was transported back to Riverside and booked into the Robert Presley Detention Center on the listed charges.
