Woman charged in 2002 Topeka double homicide

(CBS/AP) TOPEKA, Kan. - Nine years after a Topeka man and his fiancee were murdered in their sleep, Dana Chandler, the man's ex-wife, was arrested in Oklahoma on two first-degree murder charges.

The 51-year-old was arrested Monday morning outside a fast-food restaurant in Duncan, Okla., by a task force of Topeka police officers, Kansas Bureau of Investigation special agents and Oklahoma law enforcement officers.

Chandler was charged with shooting her ex-husband, Mike Sisco, and his fiancee, Karen Harkness, on July 7, 2002, in the couple's Topeka home.

Investigators said Sisco was shot seven times, while Harkness had five gunshot wounds. The killings gained national attention in October 2009 when they were featured on CBS News' "48 Hours Mystery."

Harkness was a convention sales representative with the Topeka Convention and Visitors Bureau. Sisco was a district manager for National Standard Welding Products.

Topeka police said the killings didn't appear to have come during a random burglary and ruled out robbery as a motive.

Investigators said Sisco and Harkness had won money when they visited the Sac and Fox Casino near Powhattan in Brown County, and a substantial amount of the money was still in the home when the bodies were found by Harkness' parents, Harold and Betty Worswick.

After the "48 Hours Mystery" episode aired, Hailey Sisco told The Topeka Capital-Journal she was sure her mother, Chandler, was involved in the killings. Hailey Sisco was 17 at the time of the murders, and her brother Dustin Sisco was 15.
