Romero had been serving a life sentence with the possibility of parole for second-degree murder. He was first received into the state prison system in 1996 and later received additional sentences for possessing or manufacturing a weapon while incarcerated and two separate assaults on correctional officers involving gassing.  

Forbes was received into the state prison system in April 2024. He is serving a three-year, four-month sentence for second-degree robbery, second-degree burglary and attempted second-degree robbery.
