Lisa was last seen at her home in the 3600 block of North Lister Avenue in Kansas City, Missouri, on October 3, 2011. Her mother, Deborah Bradley, put Lisa to bed in her crib around 6:30 p.m. On October 4, 2011, at approximately 4:00 a.m., Lisa’s father, Jeremy Irwin, returned home from work to find the door wide open, all the lights on, and three cellular phones missing. When authorities questioned Deborah Bradley, she initially stated that she had checked on Lisa around 10:30 p.m. the previous evening. Later, Deborah Bradley shared that she had been drinking with a friend and was unable to recall the exact time she last saw Lisa. The last moment she was certain of was around 6:30 p.m., before she began drinking, when Lisa was sound asleep in her crib. Earlier that night, multiple witnesses reported seeing a man walking approximately three miles from the home, carrying a baby dressed only in a diaper. It remains unclear if these sightings are connected to Lisa’s disappearance.
