If there was no missing person report filed until 47 years later I would take a very close look at the wife. Why didn't she report him missing?

Charles Edward Mansker Jr., 27, disappeared from Wichita, Kansas, on October 3, 1968. Known as Chuck, he was last seen locally and vanished with few clues. He is described as 5 feet 11 inches, about 195 pounds, dark brown hair (possibly balding), hazel eyes, and with scars on his upper left forehead, behind his left ear, and on his lower left arm.

No missing person report was filed until 2015, when his brother discovered the oversight and an official report was submitted. The Sedgwick County Sheriff’s Office is handling the case and has worked with the family; a private investigator was also retained. An ex-wife thought he might have gone to Mexico, but that has not been verified. Family DNA has been uploaded to databases to assist identification if remains are found.

This remains one of Sedgwick County’s oldest open missing person cases. If anyone has memories of Charles, knew where he spent time in 1968, or has information about a possible trip to Mexico, please share what is known.
