TOPEKA, Kansas (AP) – The ex-wife of a Topeka man whose slaying went unsolved for nearly a decade has been charged with two counts of first-degree murder.

The Topeka Capital-Journal reports that 51-year-old Dana Chandler was arrested Monday morning outside a fast-food restaurant in Duncan, Okla.

Chandler is accused in the July 2002 shooting deaths of her former husband, Mike Sisco, and his fiancee Karen Harkness. Both were shot multiple times as they slept in their Topeka home.

A task force of Topeka police officers, Kansas Bureau of Investigation special agents and Oklahoma law enforcement officers made the arrest.

The case gained national attention in October 2009 when it was featured on the CBS program “48 Hours Mystery.”

Chandler’s Topeka attorney, Mark Bennett, declined Monday to comment on his client’s arrest.
