URBANNA, Va. (WVEC) -- Authorities suspect arson could be the cause of a fatal fire at a Middlesex County marina that claimed the lives of two people.

Police are still investigating the blaze that broke out at the Dozier Port Urbanna Marina in Urbanna around 4:30 a.m. Monday morning.

The fire quickly spread and consumed a boathouse and storage facility. Twenty-one boats were also destroyed in the blaze, as well as two cars parked in the marina’s parking lot.

Fourteen volunteer fire departments from around the region responded to the scene to assist Middlesex County Fire and Rescue with containing the blaze, which was under control by 8:30 a.m.

The U.S. Coast Guard is on scene for environmental containment and clean up. Also assisting at the scene are the Virginia Marine Resources Commission and the Virginia Department of Emergency Management.

The remains of the two individuals who died in the fire have been transported to the Office of the Chief Medical Examiner in Richmond for positive identification.

Search and Recovery Team divers with Virginia State Police, VMRC and the US Coast Guard are checking one submerged boat and another partially-submerged boat to ensure no one was onboard either of those boats at the time of the fire.
