Police have opened a missing-person investigation to find a 54-year-old man who lived in a one-bedroom structure that burned to the ground Thursday on Mokauea Island in Keehi Lagoon.

Police said the daughter of the man, Melvin Lopez, asked police to open the missing-person case. His daughter told police that it has been a while since she has seen her father. Police also said Lopez is known to sleep under the freeway in the area.

Police said Lopez is 5 feet 6 inches tall and weighs 150 pounds. He has black hair and brown eyes.

Fire Department spokesman Capt. Terry Seelig said no body was found in the rubble of the charred structure, which was built on stilts on the Ewa end of the 13.7-acre island in Keehi Lagoon.

The fire caused an estimated $75,000 in damage.

However, fire investigators were unable to determine where and how the fire started. The investigation is closed but can be reopened if new information surfaces, Seelig said.

The Lopez home was leased from the Mokauea Fishermen’s Association. At least four families lease homes from the association, which holds a 65-year master lease from the state Department of Land and Natural Resources. The state allowed residents to rebuild as long as their houses were built to code. The master lease will expire in 2043.

The island is Oahu’s only remaining native Hawaiian fishing village, and a nonprofit group has been working to restore it.
