The Rhode Island Department of Environmental Management is investigating after a running boat with blood and broken glass inside turned up at a marina in Warwick.
Lt. Steve Criscione says the DEM was notified of the suspicious boat after it had become entangled with another vessel at Brewer's Marina at about 3 a.m. Tuesday.
The boat was found with damage to its hull and blood on the deck. Officials determined the vessel had recently been in an accident.
Criscione says boat accidents are common, but it's unusual for investigators to find nobody aboard upon their arrival.
Environmental police are investigating the incident as a boat accident, but are considering the possibility that the vessel was stolen.
