The crime of Riba-roja

During the 2010 Fallas, firefighters put out a fire in a villa in a Riba-roja housing estate. The owner of the house's vehicle was found burnt down in the province of Cuenca. Just 12 hours later, his body was found with a gunshot wound to the head. The Guardia Civil discovers that the victim's life has shadows that could explain what appears to be an execution.
