Rosio Monica Beltran, 26, was last seen on September 9, 2000, leaving the Bellbottoms nightclub in North Richland Hills, Texas, with a man she had just met, identified as Mario Alberto Prieto. Surveillance footage shows them leaving together around 1:00 a.m.; neighbors later reported hearing screams from Prieto’s Bear Creek apartment about 2:30 a.m. that same night.

Investigators found bloodstains matching Beltran’s DNA in Prieto’s apartment — notably in the bathroom and bedroom — and noted attempts to clean and repaint those areas. Witnesses said Prieto removed a heavy, foul-smelling box from the apartment the next day. Prieto fled and was tracked to San Antonio, where he died in a police shootout on September 11, 2000. Beltran’s body has never been recovered despite searches, including at a nearby landfill, and authorities consider her a homicide victim.

Does anyone have information about Beltran’s last known movements, Prieto’s activities that night, or the heavy box neighbors described?
