Lamb was last seen at a family member's home in the vicinity of the 5300 block of West Campbell street, near 51st Avenue and Maryvale Parkway. She was picked up by an unidentified man driving a white pickup truck. Lamb has not been seen or heard from since that time. Her sister reported her missing 30 days later.

Lamb had a history of dropping out of sight for several days at a time in 2002, but she had never been gone for very long and she always kept in touch with her family, which includes three young sons. Her loved ones believe she met with foul play, as it is uncharacteristic of her to be out of contact with them. Lamb's case remains unsolved.
