Karon Elaine Knight, 59, of Harper, Texas, was shot and killed at her home on May 9, 2014. She was born September 9, 1954, in Houston and was survived by her husband Joseph Knight and their children; she was also a grandmother to several grandchildren.

Authorities say Joseph C. Knight, 67, was charged with capital murder after officers found Karon and a 19-year-old granddaughter, Barbara Knight, fatally shot at the Josephine Drive residence. Joseph Knight surrendered at the scene; deputies recovered a rifle and held him in the Gillespie County Jail under $1 million bail. Gillespie County deputies investigated with assistance from Texas Ranger Kevin Wright. Few details about motive have been released and the court proceedings remained pending for years.

If anyone knew Karon, Barbara, or the family, or has information about what led to the killings, please share what you know with investigators.
