The Sumter County Does, also known as Jock Doe and Jane Doe, were two unidentified homicide victims found in Sumter County, South Carolina, on August 9, 1976. They had apparently traveled through various places in the United States before being killed in South Carolina. This was inferred from some of their belongings.

Each victim was shot three times, receiving one shot in the throat, one in the chest, and one in the back. The weapon used was believed to be a .357 caliber revolver.

Sumter County Coroner Verna Moore continued to work on the case until her retirement in 2009. The case remains unsolved. Neither of the victims' identities has been found, despite the fact that their descriptions, sketches of their faces, dental information, and fingerprints were distributed across the United States.

Authorities decided to halt the investigation until the victims' identities could be discovered.

The male victim's nickname "Jock" may have originated from the French name "Jacques." A man who claimed he had met the victims stated that he was told by the male victim that he had left his Canadian family with his girlfriend. The man said that the male victim stated that his father was a well known doctor; this supported the theory that his family was wealthy.

In the early morning hours of August 9, 1976, the young man and woman were said to have been seen from a distance by a hermit. It was said they had been dropped off on Locklair Road, a secluded dirt road between I-95 and S.C. 341 (Lynches River Road).

It is possible that the victims had their vehicle hijacked, possibly by hitchhikers. Then, upon their exiting the vehicle, someone shot them both in the back.

At 6:20 a.m., a man named Martin Durant found the bodies and contacted Charles Graham, an employee at a nearby store. Graham, in turn, contacted the authorities.

The male victim was at first believed to between 18 and 22 years of age, but his dentition suggested that he may have been older than 27. The age range was updated to be between 18 and 30 years after his case was entered into NamUs.

The forensic dentist who examined the man's teeth said he believed he was over 27 but that he had looked younger due to his clothing and build. The victim was white with an olive complexion. He had brown, shoulder-length hair, brown eyes, and very distinctive bushy eyebrows. He stood over 6 feet tall, weighed about 150 pounds, and had had extensive, elaborate, dental work that may have been performed outside the United States. This might indicate a higher socioeconomic status.
