Post Falls Police Department Lt. Greg McLean said authorities are concerned that Kristopher Loesch may be in danger following the discovery of the bodies of his mother, Tina Loesch, and her companion, Skye Hanson, near Tucson, ABC reported Friday.
Loesch, 37, and Hanson, 44, died from gunshot wounds to the head. Their bodies were found in a vehicle on the side of road on Nov. 17, hours after "America's Most Wanted" aired an episode detailing a 1998 suspected homicide case they were involved in.
Tina Loesch had been suspected of helping kill her mother, Barbara, on Jan. 8, 1998, and attempting to make it look like an accident in order to collect on a life insurance policy.
A man named Bradley Steckman later implicated Loesch in her mother's death and reached a plea deal to testify against Loesch.
ABC said after police weren't able to link Loesch to the killing, she disappeared along with her son and Hanson and have rarely been seen since.
