Wichita ? Relatives of a Wichita woman killed in a murder-suicide are suing the estate of her killer.

The Wichita Eagle reported that the estranged husband of Poppilyn Delano-Moody is bringing the lawsuit on behalf of their children in Sedgwick County District Court.

Police found the bodies of 57-year-old Michael D. Pierce and 36-year-old Delano-Moody on Jan. 29 in the Wichita house they shared.

Delano-Moody had been stabbed to death, and Pierce had a gunshot wound to the head.

Police said the couple had a history of domestic violence.

Pierce appears to have no immediate surviving family. The administrators of his estate have 30 days to respond.
