Lisa Irwin

Lisa Renee Irwin was a 10-month-old infant who disappeared from her family's home in the Northland area of Kansas City, Missouri. Born November 11, 2010, she lived with her mother, Deborah Bradley, her father, Jeremy Irwin, and two older half-brothers. According to the parents' account, Bradley said she last checked on Lisa in her crib on the night of October 3, 2011, and Jeremy Irwin discovered the child missing when he returned home from an overnight work shift in the early morning hours of October 4. The parents told police they found a window open, the front door unlocked, and lights on inside the house, and reported that three cell phones were also missing. They called 911, and an initial search of the neighborhood by police did not locate the child.

The disappearance drew intensive local, national, and federal attention. The FBI joined the Kansas City Police Department, and searches were conducted of the home, nearby wells, wooded areas, and a landfill. Police reported that two witnesses said they saw a man walking with a baby, and one of the missing phones was reported to have registered activity, including a call, around the time of the disappearance. A $100,000 reward was offered by an anonymous benefactor, and the family retained high-profile attorneys, including Cyndy Short and later Joe Tacopina. Tensions developed between the family and investigators: Bradley told the Associated Press that police accused her of involvement and told her she had failed a polygraph examination, an allegation authorities have not publicly confirmed in detail. Court records related to an October 19, 2011 search of the home noted that a cadaver dog reportedly alerted to a possible scent of human remains near the mother's bed; no remains were found and this was never independently corroborated as evidence of a crime.

No one has ever been charged in connection with Lisa Irwin's disappearance, and neither parent has been arrested or convicted. Deborah Bradley and Jeremy Irwin were described in media coverage as being scrutinized by investigators early in the case, but both publicly denied any involvement and were never named as formal suspects in charging documents. Various leads over the years, including a 2013 report of a girl in Greece who resembled age-progressed images of Lisa, were investigated and ruled out. The case has been examined in podcasts and television programs and, more recently, in a documentary series by journalist Megyn Kelly. As of 2026 the case remains open and unsolved. Lisa Irwin is still listed as a missing person by the Kansas City Police Department and the National Center for Missing & Exploited Children, which maintains an age-progressed image and notes her distinctive birthmark on her right thigh. Police have said they continue to investigate and have expressed belief that she may still be alive.
