BROOKSVILLE — Every now and again, detectives say, Anthony Rennick would pick a place at random with the help of his GPS device.
Most of the businesses were gas stations in Spring Hill. Rennick also called a Publix, a McDonald's and a Chinese restaurant.
But Rennick issued the same threat to all of them: He warned that bombs had been placed throughout their businesses and were set to explode, according to the Hernando County Sheriff's Office.
After 10 calls in nine months — and no explosions — the bomb threats might finally be coming to an end.
Hernando detectives arrested Rennick on Wednesday and charged him with 10 counts of making false bomb threats. Rennick, 40, of Spring Hill was booked into the Hernando County Jail and held without bail.
According to the arrest report, Rennick made at least three bomb threats on Sept. 30. He called three gas stations in Spring Hill — two of them Mobil, one a Circle K — and told an employee at each one that bombs had been placed at the business and were going to explode.
Detectives said Rennick also made two bomb threats on April 8, one on April 16, two on April 27, one on April 30 and a final one on May 2.
All of the businesses were subsequently evacuated and shut down, traffic patterns were altered and deputies and firefighters were called to each scene, according to the report.
On Wednesday, detectives reviewed phone records and subscriber information for a phone number registered to Rennick's mother.
The number was obtained from BellSouth after a bomb threat made May 2 to the McDonald's at 4166 Mariner Blvd.
A review of the phone calls made from the Rennick's phone number confirmed they were made to the businesses at the time threats had been called in, according to the report.
Later that day, detectives tracked down Rennick at his home in the 12400 block of Centennial Street and interviewed him at the department's district office in Spring Hill. Rennick admitted to making the bomb threats, according to an arrest report, and said he chose random locations and got the numbers and locations from his GPS.
Rennick told detectives he made the threats because he was out of work and bored.
A search of Florida public records showed Rennick has no previous arrests.
