His younger half-brother, Wesley Williams, was later convicted of murdering a woman and her three sons and is in prison. Police initially looked at Mathis as a possible suspect in those murders, but he was cleared. Even though Mathis disappeared shortly before his brother’s trial (which was later delayed), police don’t think the two events are connected.

Mathis was close to his family and girlfriend before he disappeared, so his sudden vanishing is very strange. He had some past run-ins with the law, but no outstanding warrants when he went missing. Police think drugs might be involved in his disappearance, but the case remains a mystery.
