On May 31, 2013, five-month-old Alexis Mae Johnson vanished in Oklahoma City during a tornado and the flash flooding that followed. She was with a group of adults and other children who took shelter in a drainage ditch; torrential rain caused the drainage system to flood rapidly and the current swept people away. Several of the others, including children, were found and identified, but Alexis was never recovered.

Alexis was described as a Caucasian infant with brown hair and brown eyes, wearing a onesie when she disappeared. She had a distinctive Mongolian spot on her buttock. The Oklahoma City Police Department investigated, but the force of the floodwaters made search and recovery extremely difficult and her family remains without answers.

If anyone was present that night or has information about the drainage system or searches conducted after the storm, please come forward.
