Klaus-Peter Schreiber, 74, disappeared from New Orleans in May 2015 on the morning he planned to fly solo to Ireland. Known as Peter, he left for Louis Armstrong New Orleans International Airport wearing a button-down shirt, blue jeans and brown penny loafers, and may have been wearing his gold wedding band. He has pockmarks on his forehead, a scar on the left side of his cheekbone and wears eyeglasses.

He never boarded his scheduled flight or any other flight, and the New Orleans Police Department found no record of anyone matching his name or description on airline manifests. About four months later his black 2009 Mercedes was located in a long-term parking lot across from the airport, confirming he reached the airport area. Roughly eight months after that, a homeless man turned in Schreiber’s briefcase, which contained cash and checks, to a shelter volunteer who gave it to police. His disappearance is classified as endangered and remains unsolved.

If anyone saw Klaus-Peter Schreiber at or near the airport that morning or has other information about his movements, please come forward.
