OLYMPIA, Wash. (AP) -- Josh Powell's in-laws are traveling to Olympia to discuss changes in how the state handles child protection.
Chuck and Judy Cox plan to join Republican Sen. Pam Roach at a news conference Thursday. The Cox family had cared for Powell's two young boys until he killed the children and himself in a fire earlier this month.
Roach is introducing a measure that would prohibit a child custody award to a murder suspect.
Powell's wife, Susan, has been missing since 2009 but Utah authorities never publicly labeled her disappearance as a murder. Investigators also never called Powell a suspect.
