Mario Armondo Rios Ramos, 33, was shot and killed in a parking lot at the Biltmore Apartments on Glastonbury Road in the early morning of April 9, 2022. He had been following his stolen pickup after spotting it; the truck was later found running at the scene. Investigators determined the vehicle had been used earlier that day as the getaway truck in an armed robbery at La Mexicana Mercado on Murfreesboro Pike.

Metro Nashville Police linked two people to both crimes. Detectives say Rios Ramos had given the truck to 20-year-old Gabrielle Castelianos to drive two days before his death. On May 10, 2022, Castelianos and her 25-year-old boyfriend Nicholas Washington were arrested at a South Nashville apartment on drug and gun charges after officers found multiple pistols, ecstasy, marijuana and THC vape pens. Castelianos was later charged with murder in Rios Ramos’s death, and a murder warrant was issued for Washington; both also face aggravated robbery charges for the Mercado heist.

Are there witnesses or surveillance tips from the area that could fill gaps in the timeline that morning?
