Dec. 6, 2009: Susan Cox Powell, 28, is last seen at her West Valley City, Utah, home. Police say her husband, Josh Powell, is a person of interest after he claims to have taken their two boys, Charles, 4, and Braden, 2, on a midnight camping trip in subfreezing temperatures.
Jan. 6, 2010: Friends say Josh Powell, who has been fired from his job, may be unable to keep his home in West Valley City and is moving with his children to Puyallup, where his father lives.
Dec. 6: Josh Powell and his father, Steven Powell, say Susan Powell ran away to Brazil with a missing Utah man, Steven Koecher.

Aug. 23: A Pierce County Superior Court orders Josh Powell and his wife’s father, Chuck Cox of Puyallup, to keep 500 feet away from each other. Josh Powell had alleged in a petition for a restraining order that his father-in-law had threatened him and stalked him and his sons.

Authorities said the case is not directly linked to the disappearance of Susan Powell.
