A DeBary man who turned online comment sections into his personal threat board is now headed to state prison. On Tuesday, a Volusia County judge sentenced Michael Maguire to 12 years in prison, followed by eight years of probation, after prosecutors said he spent months posting violent messages that referenced firearms and singled out members of the media.
According to the State Attorney, Florida's 7th Circuit, Maguire pleaded no contest to written threats to conduct a mass shooting or an act of terrorism and to unlawful use of a two‑way communication device. The court then imposed the 12‑year prison term and eight years of probation described in the office's public statement.
Maguire was arrested last November at his DeBary home after detectives, working with the FBI’s National Threat Operations Section, traced a series of threatening comments back to his online accounts, as reported by Law&Crime. That earlier coverage cites arrest affidavits alleging that Maguire threatened journalists and posted inflammatory YouTube comments while invoking violent past convictions.
Inside the Courtroom
Assistant State Attorney Dan Megaro handled the prosecution for the State, according to the State Attorney, Florida's 7th Circuit. The Honorable A. Kathleen McNeilly presided at the Volusia County Courthouse in DeLand and pronounced sentence, per the Seventh Judicial Circuit Court.
How Investigators Tracked the Threats
Prosecutors say Maguire’s social media posts included explicit language suggesting acts of violence, repeated references to firearms and statements directed at media figures. Investigators used account details and IP address information to tie the comments to Maguire’s phone number, home and internet service.
The case unfolded over several months as local detectives coordinated with federal partners in what officials describe as a multi‑agency probe. Earlier reporting and public court records cited by Law&Crime detail how the online trail was pieced together.
Why Officials Say It Matters
Cases like Maguire’s are a reminder that online speech can carry very real legal consequences. When comments include specific threats, identifiable targets and a clear trail leading back to an individual, prosecutors increasingly treat them as criminal conduct because of the public safety risks involved.
Local officials say the 12‑year sentence reflects how seriously investigators and prosecutors now treat threatening speech that crosses the line into credible, actionable threats. The State Attorney’s office announced the outcome on social media Wednesday, and court records along with charging documents filed in Volusia County are expected to provide further procedural detail as the case moves forward.
Authorities also encourage residents who encounter threatening content online to contact local law enforcement or available tip lines so investigators can assess potential danger before it escalates offline.
