Kieran Burke, a 44-year-old from Rathfarnham, Dublin, disappeared while visiting Yosemite National Park in April 2000. He checked into Curry Village in Yosemite Valley and was last seen on April 5, 2000, when he set off alone on what appeared to be a day hike wearing a leather bomber jacket and possibly carrying a camera. His rental car remained in the Curry Village parking lot.

Park staff did not realize he hadn’t checked out until April 11, and searches by the National Park Service through the park’s vast, rugged terrain turned up no trace. Burke was an experienced hiker who had previously trekked in places such as the Himalayas; authorities suspect he may have become lost or injured while hiking. His brother flew from Ireland to assist in the search but the family remains without answers.

Did anyone see Kieran in Yosemite around April 5, 2000, or have information about his planned hike or route?
