The State Department of Environmental Conservation sent a preliminary report last week to the Suffolk County police arson squad listing the cause as “incendiary,” meaning arson.

The fire destroyed three homes along with a commercial property in the areas of Manorville and Ridge and forced residents to evacuate.

One firefighter was hospitalized with burns. Two other firefighters were treated for smoke inhalation.

Even though state officials say it’s arson, Suffolk County police still aren’t sure. They have not determined an official cause.
