How we got here
The case centers on a 2021 homicide inside the Dade Correctional Institution in Homestead, where Marcus Terry killed his cellmate, Ray Matos, by stabbing with a pen after overpowering him. At the time, Terry was already serving a life sentence for armed burglary and armed robbery. A December 2025 jury conviction for second-degree murder led to the current life-without-parole sentence after an appeal motion was denied.
