Daniel Rush was 25 when he disappeared from Tucson, Arizona. He was last seen on April 23, 2013. At the time he was described as a White male, 6 feet tall, about 180 pounds, with brown hair and brown eyes.

Investigators and family have few answers about what happened after that day. A prominent theory is that Rush may have traveled to Mexico, possibly with another Tucson man, 31-year-old Angel Marmion, who vanished on the same day. Authorities believe the two may have left together, but concrete details about any shared plans or reasons for travel have not been made public. The Tucson Police Department is handling the investigation and the case remains open.

If anyone saw Daniel or Angel around April 23, 2013, or has information about travel to Mexico from Tucson at that time, please come forward.
