The Keddie Cabin Murders.

MUS-2026-0001

On the night of April 11, 1981, Glenna “Sue” Sharp, 36, was in Cabin 28 of the Keddie Resort in Plumas County, California, with her children and a guest. Her daughter Sheila, 14, was sleeping over at a neighbor's cabin. Her sons Rick, 10, and Greg, 5, were in a back bedroom with their friend Justin Smartt, 12.

At some point that night, Sue, her son John, 15, and John's friend Dana Wingate, 17, were bound with medical tape and electrical wire and killed. Sue's daughter Tina, 12, was taken from the cabin. The next morning, April 12, Sheila returned and found the bodies. Tina was missing. The three boys in the back bedroom had slept through it all, unharmed.

Tina's partial remains were found in 1984 near Feather Falls in Butte County, about 50 miles away. No one has ever been charged. As of September 2026, the case is officially unsolved.

   The case breaks back into national coverage. People magazine and the Sacramento Bee report on Sheila Sharp's fight for answers; Sheriff Hagwood says there are at least six living persons of interest, and that the Smartt-Boubede theory is being worked to the degree possible “to conclude or dismiss.”
