Hawaii county firefighters ended the search for a 30-year-old man who was last seen picking opihi Thursday.

Seven Big Island firefighters used off road vehicles and all terrain vehicles to comb the shoreline fronting the Kapoho lighthouse on Monday.

Peter Mahoe was last seen between noon and 2 p.m., climbing down a cliff face. The Coast Guard reported that Mahoe’s all-terrain vehicle was found 200 feet from the area he was last seen. His family was also camping close by.

The Coast Guard, Hawaii Fire Department and Hawaii Police Department conducted an intensive search spanning 1,414 square miles. The Coast Guard suspended its search on Sunday evening after failing to locate any sign of Mahoe.

Hawaii County search and rescue crews ended the search Monday night after finding no sign of Mahoe along the shoreline and ocean at Cape Kumukahi area.
