ONSLOW COUNTY -

The Onslow County Sheriff's Office announced Tuesday morning that a former Southwest High School student had been making numerous bomb threats to schools and businesses for several months.

In a news conference, Sheriff Ed Brown said 18-year-old Gerald Jackson made 20 bomb threats since mid-February.

The sheriff said four different schools were targeted-- Southwest High School,  Southwest Middle School, Southwest Elementary School and Blue Creek Elementary. Jackson made bomb threats to Southwest High School four times on separate days, investigators said.

Wendy Dobbs says she got an automated message from her daughter's school when the threats happened.

"To get that phone call that you have -- that there's a threat at your child's school, especially an elementary school -- is such a gut-wrenching feeling," Dobbs said. "How are everybody's kids supposed to enjoy the whole learning experience, when there's threats like this called in."

In addition, Jackson made bomb threats to Onslow Memorial Hospital, a Walmart and a McDonald's restaurant, according to the Sheriff's Office.

No bomb was actually found in any of the incidents.

Jackson told investigators he did not mean to hurt anyone, and that the bomb threats were the result of frustrations, Sheriff Brown said.

Jackson, of Jacksonville, has been charged with multiple counts of false bomb reports in a public building and communicating treats, investigators said. At last check, he was being held on a $75,000 bond.

Jackson had previously dropped out of Southwest High School, one of the schools targeted, officials said.
