Vital Statistics at Time of Disappearance
Details of Disappearance
Jeanette was last seen at her home by a real estate agent on January 13, 2003. On January 21, she had a phone conversation with her ex-husband. On January 25, Jeanette's husband, Lyle Marsh Montgomery, abandoned her son, Jonathan Jacob Corpuz, in a Shopko in Salt Lake City, Utah. Photographs of Montgomery and Jonathan are posted below.
Jonathan was only three years old at the time of his abandonment and could not remember his last name or the full name of his mother, so it took several days to identify him. It was then that authorities realized Jeanette was missing.
Montgomery fled after abandoning Jonathan, but he was apprehended after a few days and charged with misdemeanor child abuse. He is considered a suspect in Jeanette's disappearance. He had only been married to her for less than a month prior to her disappearance, and there have been questions as to whether or not the marriage was legal; Jeanette may not yet have been legally divorced from her previous husband when she married Montgomery. She previously accused him of domestic abuse, in October 2002.
Jonathan told Salt Lake City Police that his stepfather fired a shot at his mother, but missed. Several guns, knives, and boxes of ammunition were found in their home when authorities searched it. A large amount of blood was also found in the master bedroom, and smaller dribbles in the shower area, hallway, and entryway of the residence. There was so much blood, it soaked through the carpet and the carpet pad and stained the floor beneath. DNA tests determined that the blood was Jeanette's. The bed and dresser were missing from the master bedroom.
Montgomery attempted suicide with an overdose of drugs and alcohol in his and Jeanette's home and was treated at a psychiatric hospital before being released on February 27. After he was released from jail, shortly before midnight on April 8, 2003, he shot himself to death. He did not leave a suicide note. Authorities still believe he had something to do with his wife's disappearance, but since his death the investigation has stalled.
Jonathan now lives with his biological father in California. She has disappeared before, but always stayed in contact with her family and returned home soon. Authorities are investigating her case as a homicide. Some agencies state Jeanette was last seen on January 21, 23, or 29.
