In October 2011, a family in Kansas City, Missouri woke to every parent’s nightmare. Ten-month-old Lisa Irwin had vanished from her crib during the night, leaving behind a house filled with questions, missing phones, and a timeline investigators would scrutinize for years.

As search efforts expanded across the country, theories began spreading online. Was Lisa taken by a stranger, did someone familiar with the family know more than they revealed, or had critical details been missed from the very beginning?

More than a decade later, Baby Lisa’s disappearance remains one of the most debated missing child cases in recent memory.
