Honolulu firefighters rescued Justin Clark on Saturday, four days after the hiker left his Wahiawa home for a 3.5-mile hike on the Schofield-Waikane Trail.

Honolulu Fire Capt. David Jenkins said firefighters found Clark in the mountains about 4 p.m. He was alert and conscious, but dehydrated and exhausted.

Clark also had minor scrapes and bruises, and an injured right ankle. Firefighters picked Clark up by helicopter and took him to a landing zone at Iliahi Elementary School, where he was transfered to paramedics.

Jenkins said 17 firefighters resumed a search for Clark about 8 a.m. Saturday with a fire helicopter inserting firefighters along the trail.

Details on how firefighters came across Clark in the mountains were not immediately available. Clark was not on the trail when firefighters found him, Jenkins said.

Firefighters conducted four days of intensive searching for Clark after his mother alerted the Fire Department about his disappearance on Wednesday.

Clark left for the hike on Tuesday morning, then texted his mother about 4 that afternoon to say he fell a few times and was hurt.

His mother looked for him along the trail and called firefighters the next day.
