A second hiker who had been missing since Sunday was found dead in Maine on Wednesday, according to Baxter State Park officials. 

Tim Keiderling, 58, and his daughter Esther Keiderling, 28, both of Ulster Park, New York, left the Abol Campground on Sunday morning to hike to the summit of the mile-high Mount Katahdin. They were last seen alive around 10:15 a.m. that day. 

Their family became worried for their safety after they could not contact the pair on Sunday night, according to The Bangor Daily News.

The park officials offered condolences to the Keiderling family and their friends. 

After park authorities found their car still parked in a day-lot on Monday morning, an all-out search was launched. 

A team of 25 Maine Game Wardens, four Maine Game Warden K9 teams, 21 Baxter State Park Rangers, Maine Association for Search and Rescue members and Maine Search and Rescue Dogs teams, along with Maine Forest Service Helicopters and Maine Army National Guard Helicopters were deployed as part of the search.
