TAVERNIER -- A Florida Keys man sent nearly 80 emails threatening a detective and to blow up Monroe County Sheriff's Office substations, authorities said Saturday.
Cole Allan Peacock, 21, was charged with four counts of making false reports of planting a bomb, explosive or weapon of mass destruction against state owned property, jail records show. It was not immediately known if he has an attorney. He was being held Saturday without bond.
Peacock was charged on Wednesday with falsely obtaining a credit card, charging a large amount on the card and then paying it with fraudulent checks.
As detectives were finalizing arrest warrants, Peacock's defense attorney warned him he was going to be arrested, according to a Monroe County Sheriff's Office statement.
Det. Sgt. Dave Carey, who was working on the case, then began receiving 78 emails that appeared to be from other members of the Sherriff's Office that said there was a bomb at one of the substations and "better find it soon."
Ten emails also said"you will die," authorities said.
Peacock had been charged in February with computer related crimes and showed detectives how he could create email messages with a forged sender address.
When detectives showed up at his home Thursday evening, Peacock threatened the officers and stabbed himself in the neck with an injection commonly used to treat allergic reactions, the sheriff's office statement said.
Peacock struggled with the officers who took him into custody on outstanding warrants and on charges of resisting arrest and aggravated assault.
His computer was seized and an investigation found that the threatening emails originated from Peacock's home computer, authorities said.
No bombs were found during thorough searches of all Sheriff's Office buildings.
Peacock, who was already in jail, was then charged for the threatening emails and 10 counts of written threats to kill or do bodily injury to the detective on his case.
The FBI was also investigating the case and may bring federal charges against Peacock, authorities said.
