Details of Disappearance Crystal was last seen in Lafayette, Louisiana on February 7, 2013. She was living in a shelter for abused women at the time. She left the shelter on February 7 and was last seen the following day. She failed to attend several child custody court dates later that month. She was reported missing on February 18.
Sean Karl Grebinger, Crystal's estranged husband, disappeared at around the same time. A photo of him is posted with this case summary. The couple married in the 1990s and lived in Breaux Ridge, Louisiana. They had a stormy relationship.
In November 2012, Crystal had obtained a protective order to keep Sean away from her and their four children; she wrote that her husband had sexually assaulted her and on one occasion tried to strangle her, and she was afraid for her and her children's lives.
Sean was supposed to stay 300 feet from Crystal at all times, but he allegedly violated the protective order twice. On January 14, Crystal filed for divorce.
Bench warrants have been issued for Sean's arrest on unrelated charges. He has a long arrest record, although many of the charges against him were dropped.
His current whereabouts are unknown, although a man claiming to be Sean called the newspaper The Advertiser and said he was in Brazil and he thought Crystal was alive and possibly with relatives in the San Diego, California area. The caller's identity has not been verified.
Authorities haven't named Sean as a suspect or person of interest in Crystal's disappearance, but they would like to speak to him. They haven't said whether they believe Crystal met with foul play, but her family believes she wouldn't have willingly abandoned her children. Her case remains unsolved.
