William Wade Jr. was 16 when he was last seen in Houston, Texas, on December 21, 2016. He is about 5 feet 2 inches tall, roughly 160 pounds, with brown hair and is described as African American.

There were reportedly no obvious signs on the day he vanished that he intended to leave, which has made the disappearance particularly puzzling. The case is listed in NamUs and investigators have followed leads without a significant breakthrough; no evidence has emerged to explain what happened.

Anyone with information about William’s whereabouts is asked to contact authorities.
