The tragic case involving Gabby Petito, whose body was found in Wyoming after days of searching earlier this month, has brought renewed interested to missing persons investigations involving those who disappeared during outdoor travels or in U.S. national parks, including one Irish hiker who has not been seen in over three months.   

Cian McLaughlin, 27, was last seen in the afternoon or evening of June 8 in Wyoming’s Grand Teton National Park. No new information regarding the search for McLaughlin has been released since June 23, when the National Park Service said a tipster had told them they spotted McLaughlin in the southern portion of the Bradley/Taggart moraine. 

"The individual reported McLaughlin was headed south towards Taggart Lake and had a conversation with McLaughlin where he described where he worked, that he’s from Ireland and currently living in Jackson," authorities said at the time. "The reporting party continued hiking towards Bradley Lake and did not see McLaughlin again that evening."

Authorities said McLaughlin’s future plans were "unknown" and are asking anyone with information regarding his whereabouts to contact the agency’s investigative services branch at 888-653-0009.
