Key West man arrested in Marathon after 911 threats, struggle with deputies

A Key West man’s repeated 911 calls from a Marathon gas station escalated into alleged threats to kill deputies, a foot chase and a physical struggle that ended with him in a restraint chair at the jail. Monroe County Sheriff’s Office deputies arrested Corey Wade Dennis, 33, on May 27 in Marathon after the calls came in around 4:46 p.m.

Deputies said Dennis used profanity while complaining about law enforcement and allegedly threatened to kill officers during the calls to Monroe County 911 Communications. When deputies contacted him, they said he appeared intoxicated, had slurred speech and was carrying a large cup of alcohol.

The encounter quickly turned physical. Investigators said Dennis punched and pushed deputies while trying to flee on foot, then kicked another deputy after he was taken to the ground. Deputies later took him to Fishermen’s Hospital for medical clearance before jail booking, but they said he kept resisting. He was ultimately placed in a restraint chair at the jail.

The reported charges include threatening to kill law enforcement officers, battery on a law enforcement officer, resisting arrest, disorderly intoxication and misuse of 911. The case puts a hard edge on a recurring local problem: when emergency lines are tied up by angry, intoxicated or abusive callers, deputies and dispatchers lose time that should be reserved for real emergencies.

Monroe County Government says immediate emergencies should be reported by dialing 911. For non-emergency law-enforcement matters, the county lists separate contact numbers, including the Marathon Substation at 305-289-2430. Florida statute 365.171 says the purpose of the statewide 911 system is to give the public rapid direct access to public safety agencies, while Florida statute 836.12 covers threats or harassment.

The Marathon arrest also fits a pattern deputies have faced in recent local cases, including another incident in which a suspect was accused of threatening to kill a deputy and assaulting officers during an arrest. In a county where law enforcement already covers long stretches of U.S. 1 and multiple Keys communities, cases like Dennis’ show how fast a nuisance call can become a dangerous confrontation.
