Rueben Zavala was 28 when he disappeared from his Tulsa, Oklahoma apartment after leaving at about 9:00 PM on Sunday, January 30, 2011. He is described as a Hispanic male, between 5 feet 2 inches and 5 feet 4 inches tall, weighing 140 to 160 pounds, with black hair and brown eyes. A missing person report was filed with the Tulsa Police Department on January 31, 2011.

There were no immediate signs of foul play, no note, and no clear indication of where he was headed that night. The case later received an entry into the National Missing and Unidentified Persons System in April 2019, but investigators have reported few leads and no substantial public developments since the initial investigation.

If anyone knew Rueben, saw him on the evening of January 30, 2011, or has information about his whereabouts, please come forward and share what you know.
