A 44-year-old Florida man has been sentenced to life in prison for fatally shooting his wife and living with her decomposing body for three days before setting their Miami apartment on fire, authorities said.
Background
Marcus Aron Sanchez pleaded guilty to one count each of murder and arson in connection with the August 2024 death of his wife, Jenny Miguel. The couple lived together in an apartment complex in the 3000 block of SW 13th Street in Miami-Dade County. According to investigators, after killing Miguel, Sanchez remained inside the residence with her body for several days before dousing the home in gasoline and igniting it. He then drove himself to a nearby hospital while suffering severe burns across his body.
The Investigation
Miami firefighters responded to the apartment complex shortly before 2 a.m. on August 18, 2024, after reports of a dwelling fire. Upon arrival, first responders discovered Miguel's burned body inside the residence. Around the same time, Sanchez was being treated at a local hospital after driving himself there and telling authorities he had killed someone. Coral Gables police officers who spoke with Sanchez documented his confession in a probable cause affidavit. According to that document, Sanchez told investigators he got into an argument with Miguel because she claimed to have killed his children. He stated that he shot her once in the head and once in the heart. When asked about his burns, Sanchez explained he poured gasoline throughout the home and set it on fire while still inside. "The body was rotting, and I didn't know what to do with the body," Sanchez reportedly told hospital staff who treated him for his injuries. Surveillance footage from a Chevron gas station confirmed Sanchez purchased a 5-gallon fuel can with cash at 12:46 a.m. that same morning before filling it with gasoline and driving away. Miguel worked as a payroll clerk for the Miami Police Department for more than 15 years, according to colleagues who attended Wednesday's sentencing hearing.
The Charges
Eleventh Judicial Circuit Judge Christine Hernandez sentenced Sanchez on August 20, 2026, to life in a state correctional facility after accepting his guilty plea to murder and arson charges. The prosecution sought the maximum sentence given the circumstances of the crime, while defense attorneys had requested a 25-year term. During his sentencing, Sanchez offered an apology to Miguel's family. He claimed he became paranoid while using drugs and started hearing voices before the killing. He maintained he was not suicidal and said he burned himself by accident.
