Lynn was reported missing by her husband, David Labon Bush, on December 9, 1990. He stated he had last seen her the day before, when she went to the Buttrey's grocery store on 12th and Beverly in Casper, Wyoming. She never returned home. David stated that the next day he found her pickup truck, a 1985 Ford F-150 with vanity license plates reading 1T-Bush, in the parking lot with the door ajar and the keys on the ground. A receipt inside the vehicle showed Lynn had purchased groceries at 5:30 p.m. on December 8.

David stated he did not report his wife missing sooner because he thought she had left of her own volition to get back at him for his marital infedelities. Photographs of David are posted below this case summary.

Lynn's loved ones did not believe David's story, as the couple's toddler was left behind and they did not believe Lynn would abandon her daughter. Lynn's parents fought for and won custody of the child after Lynn's disappearance. David was subsequently charged with several crimes unrelated to his wife's disappearance, including burglary, voter fraud and possession of false identification. Lynn was declared legally dead in 1999.

In August 2006, David was charged with first-degree murder in connection with his wife's disappearance. Authorities stated they had uncovered new evidence which lead to the charges. Among other things, Lynn's blood was found in the family's pickup truck and in a vodka bottle inside David's house. David had allegedly made incriminating statements to others, speaking of having Lynn's body in a freezer and telling cellmates in jail that he had beaten and shot his wife. After Lynn's disappearance, David's girlfriend moved into the Bush home and forged Lynn's name on legal documents. A person who served with David in the National Guard said David had taken several items from the unit, including two body bags, around the time Lynn disappeared.

David maintains his innocence in Lynn's case, but he was convicted of his wife's murder in March 2007, after a ten-day trial. Lynn's remains have not been recovered, but foul play is suspected in her case due to the circumstances involved.
