Marcus Aron Sanchez, a 44-year-old Florida man, has been sentenced to life in prison for fatally shooting his wife and then setting their apartment on fire while her body decomposed inside, authorities said.
Background
The case dates back to August 2024, when Jenny Miguel, a payroll clerk who had worked for the Miami Police Department for more than 15 years, was killed in what prosecutors described as a calculated act of violence. According to court records, Sanchez and Miguel were married at the time of her death.
Miami firefighters responded to an apartment complex in the 3000 block of SW 13th Street shortly before 2 a.m. on Aug. 18, 2024, regarding a dwelling fire. Upon arriving, first responders discovered a woman's burned body inside the residence. Around the same time, Sanchez arrived at a nearby hospital with severe burns covering his body after driving himself there and telling authorities he had killed someone.
The Investigation
According to a probable cause affidavit, Sanchez told a Coral Gables police officer that he had gotten into an argument with Miguel because she allegedly told him she had killed his children. "Sanchez states that he shot the female 1 time in the head and 1 time in the heart," the affidavit states.
When Sanchez sought treatment at the hospital, a nurse told investigators he was screaming for help. 'She pushed me to the edge,' he said, according to the affidavit. '[Miguel] told me she killed my kids. I lost it. I got a gun and shot her 3 days ago. The body was rotting, and I didn't know what to do with the body.'
Sanchez explained that he poured gasoline throughout the home and set it on fire while he was still inside, sustaining severe burns in the process. He stated he was not suicidal and had burned himself by accident.
Surveillance footage from a Chevron gas station showed Sanchez arriving at 12:46 a.m. on Aug. 18, purchasing a red 5-gallon fuel can with cash, and filling it with gasoline before driving away—evidence that suggested premeditation in the destruction of evidence.
The Charges
Eleventh Judicial Circuit Judge Christine Hernandez presided over Wednesday's sentencing hearing where Sanchez pleaded guilty to one count each of murder and arson. The prosecution sought life imprisonment based on the severity of the crime, including the prolonged neglect of Miguel's body before the fire was set.
At sentencing, Sanchez apologized to Miguel's family, telling the court he became paranoid while using drugs and started hearing voices, according to WTVJ. He claimed he grabbed his gun and shot Miguel twice before eventually deciding to burn everything down.
Miguel's daughter delivered a victim impact statement directly addressing Sanchez: 'I want you to die,' she reportedly told him. 'I will never forgive you.' The courtroom was filled with Miguel's family as well as police officers who had worked alongside her for more than 15 years and wanted to honor their former colleague.
