An emergency shelter set up by the Red Cross at ‘Iolani School is expected to remain open today to assist residents of the Marco Polo high-rise who were displaced by a deadly five-alarm fire that swept through multiple floors of the 36-story building Friday.

The shelter registered 110 evacuees Friday night, but was mostly empty on Saturday afternoon as Marco Polo residents returned home to check out damage. If the units were livable, residents were allowed to stay, said Leonard Rosa, who works in security at the condominium building located at 2333 Kapiolani Blvd. next to Ala Wai Community Park.

The 568-residential-unit building was built four years before the city began requiring sprinkler systems.

“We’ve had a lot of people come back, but I’m not sure how many,” Rosa said. “It’s been a very rough period the last 24 hours or so.”

Three people were killed and a dozen were injured in the fire that broke out Friday afternoon. Four of them, including a firefighter, were taken to a hospital in serious condition. The firefighter was treated for heat exhaustion and released, Honolulu Fire Department spokesman Capt. David Jenkins said Saturday.

Douglas Hesley, branch president of Associa Hawaii, the management group that runs the Marco Polo building, said in a brief statement Saturday that there will be an emergency board meeting to discuss recovery efforts.

Hesley said, “Our thoughts and prayers are with the Marco Polo community.”

Jenkins said Friday that at least 100 fire personnel and more than 30 HFD units responded to the fire. HFD responded at 2:15 p.m. to the initial call for a fire on the 26th floor, but the blaze spread to the 27th and 28th floors and involved multiple units. It took more than four hours to get the fire under control.

Jenkins said the fire was declared extinguished by midnight, but firefighters remained throughout the night to monitor the scene and put out any flare-ups. Fire investigators have not yet determined a cause of the blaze, nor is there an estimate of the damage, he said, adding that a dozen units were “heavily damaged.”

At the ‘Iolani School shelter on Saturday, Red Cross shelter manager Brian Nakamura said more Marco Polo residents were expected to return since more than 50 units still could not be accessed. All the units on floors 26, 27 and 28 were inaccessible, and residents were also prohibited from returning to some units on floors 24, 25 and 29, he said.

Hideko Turner, an 89-year-old who had lived in the Marco Polo for many years, was one of the residents at ‘Iolani School on Saturday. Turner, who cannot speak due to medical issues, sought comfort from passers-by as she shivered on a cot.

Red Cross volunteers offered blankets and words of comfort, but it’s unclear what the future will hold for Turner and other challenging cases.

“It could be awhile. Insurance will have to figure it out,” Nakamura said. “We have caseworkers ready to assist people who are in immediate need, but we were surprised that the turnout was really low on Saturday.”

Caseworkers will be available again today from 9 a.m. to 5 p.m. at the shelter, he said.

Tina Doty, a Red Cross volunteer caseworker, said the team will assist Marco Polo residents with emergency food, clothing and hygiene needs. They also can provide mental health support and make referrals to help residents with other needs like finding replacement housing.

“People are coming to the shelter distraught and overwhelmed. They are in shock realizing that they don’t have a place to live anymore,” Doty said. “We’re here to comfort and let them know they are in a safe place.”
