A Lanai home and three vehicles, including a new Hummer, were destroyed in a house fire Saturday morning, a Maui County Fire Department spokesman said.

Witnesses said the fire started near the vehicles and spread to the structure, but the cause is still under investigation, Capt. Bram Denhaan said.

More than half the home was ablaze when firefighters arrived at the corner of Jacaranda and Third streets in Lanai City around 7:45 a.m., Denhaan said.

There were no injuries.

The owner had gone to the store and was not home when the fire broke out, he said.

Helping extinguish the fire were a Lanai airport fire crew and Lahaina firefighters who arrived via rescue helicopter, Denhaan said.
