Christopher Sanders, 40, was last seen on August 13, 2017, in Monahans, Texas. He had been living in a camper while working for an oil rigging company and left that morning for a walk along Interstate 20; he never returned. He was last seen wearing a black shirt with TCU on it, blue jeans, boots, and a black hat.

Sanders’ phone was found turned off and there was no further activity on his credit cards. His family say he had been diagnosed with bipolar disorder and high blood pressure and may have become disoriented if he stopped taking medications. The night before he disappeared he told his wife he felt tired and overwhelmed. Extensive searches and appeals for information have not located him and the case remains open.

If anyone saw Christopher near Monahans or along Interstate 20 around August 13, 2017, or has information about his whereabouts, please contact local law enforcement.
