Background information and Notes

Karl Karlsen, the man who killed his son for insurance money in 2008 in Seneca County, will spend the rest of his life in prison for murdering his first wife.

Karlsen was sentenced to serve life in prison without the possibility of parole by a Calaveras County judge. The sentence came weeks after Karlsen was found guilty of killing Christina Karlsen in a fire in 1991.

Christina Karlsen died trapped behind a boarded-up window in the smoke-filled bathroom of her California home on New Year’s Day in 1991. Karlsen and the couple’s three children - including Levi, the son Karlsen would later kill - escaped.

Karlsen cashed in on his wife’s $200,000 life-insurance policy and moved his family to Seneca County, New York.

Calaveras County District Attorney Barbara Yook said that Karlsen will have to serve his two murder sentences consecutively, meaning he must finish serving time in New York before he starts serving time in California.
