Aileen Gardenia Nava, 23, was found dead at a house in the 1100 block of Blalock in Houston on August 18, 2015. Police responded to a shooting call about 4:20 a.m.; Nava’s boyfriend, Mario Abigail Ramirez, then 23, told officers she had shot herself. Nava was pronounced dead at the scene.

Homicide detectives later identified Ramirez as a suspect after finding inconsistencies in his account. He was arrested and charged with murder in the 184th State District Court. In May 2016 Ramirez pleaded guilty and received a 40-year prison sentence; the court found he had tried to make Nava’s death look like a suicide.

Anyone who knew Aileen or who has information about the case is asked to come forward.
