The Keddie Murders is an unsolved 1981 American quadruple homicide that occurred in Keddie, California. The murders took place in cabin 28, during the late evening of April 11, 1981, or early the following morning. The victims were Glenna Sue Sharp (née Davis), known as Sue (age 36), her son John (age 15), and his friend, Dana Wingate (age 17). At some time after the crime was discovered, Sue's daughter, Tina (age 12), was reported missing. Her skull and several other bones were recovered in 1984 in Camp Eighteen, California, which is in Butte County.
Glenna "Sue" Sharp, 36, and her five children had been renting the cabin since November 1980. At approximately 7:45 AM on the morning of April 12, Sheila Sharp, upon returning from the sleepover next door, discovered the tied-up bodies of Sue, John and Dana in the home's living room. Plumas County Sheriff's deputies later determined Tina Sharp was missing from the location. The murders have been commented upon for their particular viciousness.
After approximately 4,000 man-hours spent on the case, it grew cold but, in 1984, the cranium portion of a skull was recovered near Feather Falls in neighboring Butte County, a distance of roughly 63 miles (2 hours 12 minutes) from Keddie. Butte County Sheriff's Office released both the original and back-up copy of the audio recording of the 'anonymous call' to an undisclosed member of law enforcement.
As of November 2017, no arrests have been made in connection with the Keddie murders, although two suspects who had criminal records, now deceased, have been proposed. In 2004, Cabin 28 was demolished.
On March 24, 2016, a hammer matching the description of a hammer suspect Martin Smartt said he lost shortly before the murders was taken into evidence by Plumas County Special Investigator Mike Gamberg. Sheriff Hagwood stated, "the location it was found... It would have been intentionally put there. It would not have been accidentally misplaced."
