Overview

On the night of April 11–12, 1981, four people were killed inside Cabin 28 in the small railroad town of Keddie, Plumas County, California: Glenna 'Sue' Sharp, 36; her son John Sharp, 15; John's friend Dana Wingate, 17; and, it was later determined, Sue's 12-year-old daughter Tina Sharp. Sue's 14-year-old daughter Sheila discovered three of the bodies on the morning of April 12 after spending the night at a neighbor's; three younger children in the cabin were unharmed. Tina was missing from the scene, and her remains were found in 1984 near Feather Falls in Butte County. The quadruple homicide remains officially unsolved despite renewed investigation in the 2010s.

Where it stands

The case remains unsolved. Beginning around 2016, the Plumas County Sheriff's Office and special investigator Mike Gamberg publicly reported new developments, including a hammer recovered from a pond near the crime scene in March 2016 and, announced in April 2018, DNA from a strip of medical tape at the scene that investigators said matched a known living suspect; no charges have resulted. Two long-discussed suspects, Martin 'Marty' Smartt and Severin John 'Bo' Boubede, are both deceased (Boubede in 1988, Smartt in 2000). Investigators have said they believe more than two people were involved and that the original 1981 investigation was deeply flawed.
