Around 11 p.m. on Nov. 15 -- hours after the segment aired -- the Pima County Sheriff's Department in Tucson, Ariz., responded to a report of two possibly deceased women in a white Dodge Durango parked along the side of the road in a rural part of the county.
Inside, police found Loesch and Hanson, both dead from single gun shot wounds to their right temples.
The medical examiner ruled the cause of death a murder-suicide, but Pima County Sheriff's Department Deputy Dawn Barkman said two suicide notes found in the car -- one from Loesch, one from Hanson -- made it clear the women had a suicide pact.
Loesch said he was told that it was his sister who shot Hanson, then turned the gun on herself.
Police from Post Falls and Pima County are now continuing to piece together the women's lives in Tucson.
Hanson had apparently started another home-improvement business, McLean said, but was unlicensed and did not pay taxes. They had not changed their names legally, but were known in town by different first names -- Loesch was Dawn and Hanson was Katie.
McLean said neighbors in Tucson told Post Falls investigators that Kristopher had been living with his mother in 2002, but she told them she had sent him to live with his father because he was too much to handle.
Neighbors told police -- who do not know who Kristopher's biological father is -- that Loesch said he was being sent to live with his father in Spokane.
McLean said Post Falls police are looking to interview Twyford and Cassel, who they believe have information about Kristopher's whereabouts or his life in the past decade.
Phillip Wetzel, Cassel's Spokane-based lawyer, said his client hasn't seen the boy, "not for many, many years."
A message left with Twyford at her law practice was not returned.
McLean said the U.S. Marshals Service are now involved with the search to find Kristopher.
Chuck Loesch, living in Gearhart, Ore., said family members have been trying to connect the pieces that made up his sister's life in the past decade. Looking back, Chuck Loesch said he's now convinced that his sister and Hanson were directly involved with the murder of their father in 1996. No charges have been filed in the death of Gary Loesch.
"I think it's brought our family closer together," he said of the ordeal. "Each family member has heard different stories."
