Juliana was last seen at her residence in Arlington, Washington on June 30, 1989. She left all of her personal belongings behind at her family's home, including her vehicle. Juliana has never been heard from again. Juliana was married to David Charles Schubert in 1989, but divorce proceedings were nearly complete at the time of her disappearance. David has been the prime suspect in Juliana's disappearance since 1989. David was charged with Juliana's murder in 1994, but charges were eventually dropped when the lead investigator died of leukemia. Juliana's relatives won a cash settlement against David for their two children in 1998, when a civil trial jury found that David was responsible for his wife's murder. The Schubert's' sons publicly supported their father. They told investigators that Juliana departed from their residence with an unidentified blonde woman driving a red vehicle. David was charged with first-degree murder in Juliana's case in October 2001. Authorities said that he spoke to at least one witness while divorce proceedings were underway and mentioned that he wanted to kill Juliana to find "peace" for himself. Investigators have always believed that David hid his wife's remains at an undetermined location. David has stated that Juliana called him from Colorado several days after her 1989 disappearance. He claims she wanted time to herself and simply never returned to Washington. Her family said that she would never have abandoned her children by her own decision.
