The cause of the 235 Lake Shore Dr. fire Thursday evening remains under investigation, according to Pleasantville Fire Department Chief Manny Colmenares.

"Multiple calls came in" reporting the fire at approximately 6:55 p.m. Thursday, Colmenares shared. He said neighbors witnessed the fire, though he does not believe residents of the single-family home were inside at the time.

While one 911 caller reportedly said an aircraft hit the building, Colmenares denied that theory and said there was no evidence at the scene to back it up.

"The fire was on the lefthand side of the building," he said. "When I pulled up, the deck was fully involved."

Colmenares estimates the flames were put out within about 25 to 30 minutes after fire departments began arriving.

Local fire departments, along with Westchester County investigators, were examining the home in and outside as late as midnight Friday. A county canine was also on-scene.

The house now "is not habitable," Colmenares said. "They are not going to be able to spend the night there."

As far as the home's damage—"We had a roof collapse, the first floor collapsed, the basement is definitely flooded out and the roof from one end to the other has also been compromised," the Chief said.

It appeared just the two-car garage on the lower righthand side of the home was unaffected by the fire and subsequent deluge of water from the departments' hoses.

According to county investigators' preliminary reports, it is "undetermined" if the fire's origin is suspicious, Colmenares said.

While it is not yet known how the fire started, Colmenares said it likely began outside the home.

"The county is here, they are still doing their investigation," he said.

Firefighters continued to operate the hose line to the blaze as of 7:45 p.m. The fire weakened the home's structure and much of the roof collapsed.

By 8 p.m., most of the flames were extinguished and firefighters were able to approach the front door.
