A Miami couple is facing animal cruelty charges after their dog died inside their pickup truck outside an Islamorada restaurant last month, when the vehicle's engine reportedly shut off while they were eating. Miguel Jimenez, 63, and Dayany Jimenez, 40, told investigators they had left the animal in the truck with the engine running and the air conditioning on while they went inside to dine.
Deputies with the Monroe County Sheriff's Office responded to Mile Marker 81 along Old Highway in Islamorada on August 23 after receiving a report of an injured bulldog or terrier-type dog, according to the Monroe County Sheriff's Office as reported by the Tampa Free Press. That stretch of Old Highway sits in Upper Matecumbe Key, a commercial corridor lined with seaside restaurants, marinas, and public recreation areas, according to Keys Weekly.
According to investigators, the couple said the truck's engine shut down when they returned to the vehicle, cutting off the air conditioning that had been keeping the interior cool. By then, the dog had died inside the cab. Deputies notified the Florida Keys SPCA, and authorities went on to secure arrest warrants for both Miguel and Dayany Jimenez, who were booked into jail Tuesday.
How Fast a Parked Truck Turns Deadly
The physics behind the tragedy are well documented. Research from the American Veterinary Medical Association shows interior air temperatures in a parked vehicle can climb nearly 20 degrees Fahrenheit within just 10 minutes and 30 degrees within 20 minutes, and cracking a window barely slows the buildup. August is historically the hottest month of the year in Islamorada, with average highs near 90 degrees and heat indices climbing to about 95 degrees, according to data from Weather Spark. In that kind of humid, tropical heat, an unexpected engine shutdown or air conditioning failure can turn a vehicle cabin into a fatal environment within minutes.
The case now sits at the intersection of two Florida statutes. Under Florida Statute § 828.12, animal cruelty can be charged as a first-degree misdemeanor carrying up to a year in jail and a $5,000 fine, or elevated to third-degree felony aggravated animal cruelty — punishable by up to five years in prison and a $10,000 fine — when negligence or intentional acts cause an animal's cruel death or severe suffering, according to the Florida Senate. Whether prosecutors pursue the misdemeanor or felony version of the charge against the Jimenezes has not been reported.
A Pattern of Hot-Car Enforcement in Monroe County
This is not the first time Monroe County law enforcement has pursued charges over a pet left in a hot vehicle. In July, deputies arrested a 20-year-old woman in Key Largo after a dog was left unattended in a hot SUV with the windows closed and the engine off, with interior temperatures exceeding 100 degrees, per a Charlotte County Neighborhood Watch bulletin hosted on HOA Express. And in November 2024, a Marathon man was convicted on animal cruelty charges after leaving a dog locked in a hot car the previous July, an incident that left the animal suffering critical heatstroke and neurological distress, Keys Weekly reported at the time.
Monroe County Sheriff Rick Ramsay has repeatedly stated the department maintains a zero-tolerance policy on animal cruelty and will aggressively investigate and press charges against violators, according to CBS News. The Florida Keys SPCA typically assists the sheriff's office in these cases by sheltering rescued animals and arranging veterinary necropsies to determine exact causes of death for prosecutors, the outlet's report notes. Back in December 2022, deputies arrested an Islamorada resident after witnesses reported two kittens thrown from a moving vehicle on U.S. 1 near Mile Marker 87, a case detailed by WKMG at the time.
What Bystanders Can Legally Do
Florida law also gives ordinary citizens a legal option if they spot an animal in distress inside a locked car. Under Florida Statute § 768.139, Good Samaritans are shielded from civil liability for property damage if they break into a locked vehicle to rescue a domestic animal in imminent danger, as long as they call 911 before or immediately after and use no more force than necessary. It's a protection designed specifically for moments like the one that unfolded outside the Islamorada restaurant, though in this case it was the dog's owners, not a bystander, who were left facing charges after deputies were called to the scene.
