A Silver Alert for a missing Independence County man has been canceled after he was found dead. Independence County Sheriff Shawn Stephens said that 71-year-old Wainwright Jackson Humphryes of Oil Trough was found dead Thursday morning. He apparently crashed his truck where he was last seen, the sheriff said. Foul play is not expected. He was last reported to be seen in the 2600 block of Blackland Road in the Oil Trough area. Humphryes had been missing since Tuesday. Humphryes’ family said he suffered from dementia and had heart problems, as well as used oxygen and suffered from COPD.
