Lee County Sheriff Carmine Marceno announced Thursday that his team arrested a Lehigh Acres man accused of threatening a mass shooting.
Joseph Ricardo Devolliere, 27, was charged with intimidation sending a written threat to conduct a mass shooting.
Devolliere made the threat in text messages to several employees at the FedEx ground facility in Fort Myers, Marceno said.
Detectives learned of the threats Tuesday afternoon.
Devolliere was recently fired from his job at FedEx due to inappropriate behavior. One incident involved sexual comments toward a juvenile and another incident detailed an act of aggression involving a box cutter used to slash a table, Marceno said.
Both of those incidents were not reported to law enforcement at the time.
Analysists discovered Devolliere had several previously documented incidents making threats in the Fort Lauderdale area. Some of those threats involved the use of a firearm.
Detectives executed a search warrant at his home, where they found a firearm and ammunition, Marceno said.
Devolliere was arrested Wednesday evening and is in Lee County Jail on no bond. He has a court hearing scheduled for Dec. 14.
