Crews were at the scene of a fire in Warwick Monday morning.
NBC 10 News saw multiple police and fire trucks along Richmond Drive around 6 a.m.
Authorities were still there as of 8:15 a.m., with Dream, an accelerant detection K-9, also working the scene.
"We run her through to look for gasoline and gasoline-type products around the area where the fire started," Deputy State Fire Marshal James Given told NBC 10.
Video shows Dream standing on the hood of a car that was parked in the driveway of the home.
The trunk of the car was charred, as was the garage.
"The investigation is really early at this point, so we're seeing whether it was car first or house," Given said. "There was a vehicle involved, obviously, and the outside of the house. It's still early in the investigation."
He added that no one was hurt.
