Robert Ronald Tippit, known as Bob, was 36 when he vanished from Kansas City, Missouri. The last confirmed contact was January 1, 1980, although people who knew him suggest he was last seen in 1977 or 1978. He is described as a white male, brown hair and brown eyes, 5 feet 10 inches and about 180 pounds, and may have used aliases including Richard Allen Lais, Ron Roberts, and Arthur Dewuane Tippit.

Reports say Tippit had traveled to California and in 1979 testified in a court case against a suspect tied to prostitution. He was reportedly beaten after that testimony and said people were after him; he then returned to Topeka before moving to Kansas City, where he was last officially located. The relationship between the assault, his testimony, and his disappearance remains unresolved.

The Topeka Police Department is listed as the investigating agency. Does anyone have memories of Bob, his whereabouts in the late 1970s, or information about those aliases?
