Memorial Day weekend in Key West is supposed to be about sunshine, cold drinks, and good memories. For one suburban Chicago man, it became something else entirely: a criminal record, a busted field sobriety test, some fence-related injuries, and enough charges to fill a very embarrassing rap sheet.
John Mack, 38, of La Grange, Illinois, was arrested Saturday after Key West Police Department officers say he climbed into an unoccupied police cruiser at the Key West Bight Marina and took it for a spin around the parking lot, all while allegedly under the influence of alcohol. The incident unfolded near Dante’s Key West Pool Bar and Restaurant on Caroline Street, where an officer was working an off-duty security detail, apparently keeping the peace at a pool bar that, on this particular Saturday, would not keep its own peace for long.
Surveillance footage captured the moment around 6:20 p.m. when Mack strolled out of the bar with two companions, stopped near the patrol vehicle, and then, seemingly on impulse, opened the door and got in. He then reportedly put the cruiser in drive and nearly struck two of those same friends he had been walking alongside moments before. Whether they remained his friends after that is unclear.
A nearby security guard alerted the off-duty officer, and additional KWPD units responded as Mack drove the cruiser around the marina parking lot. Officers eventually located him outside the Boat House Bar and Grill, which is nearby, where he reportedly claimed he had drunk somewhere between three and six Corona beers. Mack was arrested, failed a field sobriety test, refused a breathalyzer, and sustained cuts from a fence while resisting. He is now facing seven charges.
A Lineup of Charges That Would Make Any Defense Attorney Wince
The list of counts Mack faces is, by any measure, a lot. Key West police charged him with DUI, burglary, grand theft, grand theft of law enforcement equipment, reckless driving, refusal to submit to DUI testing, and resisting arrest without violence. That is seven separate charges stemming from what was, at its core, about 15 minutes of very bad decision-making near a marina.
The inclusion of “grand theft of law enforcement equipment” is a charge that carries its own weight beyond a standard vehicle theft. Stealing any car is serious, but stealing a marked police cruiser, complete with its equipment, communications hardware, and official insignia, lands in a separate legal category. Florida takes the theft of government property and law enforcement equipment seriously, and prosecutors tend to treat these cases accordingly. Legal experts note that when a stolen vehicle is identified as emergency or law enforcement property, charges and potential penalties escalate significantly beyond what a standard grand theft auto case would carry.
Adding further complexity to his situation, police say Mack did not have a valid driver’s license at all. He was carrying an Illinois identification card, not a license, meaning he had no legal right to be driving any vehicle that day, let alone a police cruiser.
Key West Has Seen Its Share of Unusual Vehicle Incidents
If you think a tourist stealing a police car is the most outlandish vehicle-related incident Key West has ever seen, the city’s history suggests otherwise. In a case that made national headlines, a North Carolina tourist once stole an ambulance and drove it down the famous Duval Street with the emergency lights on, later telling police she had done it to get law enforcement’s attention because she could not find her friend. She reportedly thanked the officer for the ride to the jail. Key West is also no stranger to the theft of its beloved Conch Tour Train, a novelty tourist attraction that has been stolen on at least one occasion by someone who, according to police, picked up random passengers along the way before being arrested at the Southernmost Point Buoy.
The Florida Keys, and Key West in particular, draw enormous crowds during holiday weekends. Memorial Day weekend is widely considered the unofficial start of summer in Key West, bringing a long-weekend energy to the island with more people, more events, and more of that end-of-spring momentum that makes the holiday feel worth celebrating. With those crowds come elevated risks. More people, more alcohol, more impulsive behavior, and occasionally, someone who decides a police cruiser looks like a reasonable vehicle to borrow.
What This Incident Teaches Us About Holiday Weekend Decision-Making
There are a few fairly obvious lessons embedded in this story, and they are worth naming plainly. First, the presence of a police officer, even an off-duty one working a private security detail, does not make a nearby patrol car off-limits. If anything, the officer being visibly nearby should have been a signal to leave the cruiser alone. Second, and perhaps more fundamentally, driving under the influence already carries serious consequences on its own. Layering on the theft of a law enforcement vehicle, reckless driving, and resistance at the time of arrest turns a bad night into a potentially life-altering legal situation.
Refusing a breathalyzer, while it may seem like a way to avoid evidence, is itself a chargeable offense in Florida and rarely works in a suspect’s favor. Courts and juries are well aware that people tend to refuse tests when they know the results would be damning. Legal experts advise that anyone arrested on suspicion of vehicle theft should exercise their right to remain silent and consult an attorney rather than attempting to explain their version of events to police directly. In Mack’s case, whatever explanation he offered at the scene, it did not prevent his arrest.
There is also the matter of the no-license detail. Driving without a valid license, even in ordinary circumstances, is an offense. Doing so while allegedly intoxicated, in a stolen police cruiser, without a license, after nearly hitting two people, transforms the situation from a bad judgment call into something with genuinely serious legal consequences on multiple fronts.
What Comes Next for John Mack
As of Tuesday, Mack no longer appeared on the active Florida Keys jail roster, suggesting he had been released by that point, whether through bond or other means. That said, the charges themselves do not disappear with a release. The case will move through the Monroe County court system, and with seven counts, including felony-level theft charges, he faces a process that will likely involve legal fees, court appearances, and potentially significant penalties if convicted.
Key West will, of course, keep celebrating. The pool bars will keep pouring, the marinas will fill back up, and Memorial Day weekend 2027 will arrive right on schedule. For Mack, though, this particular holiday weekend left a mark that will outlast any sunburn.
