RedactedNarrative: Marine Patrol was dispatched to a scene of an accident heard by an individual hearing two vessels collide. The officer responded to the scene and negative contact with boats involved in the accident. Approximately one hour later a call from a boater involved in the collision wanted to report a collision with another vessel. The operator of the second vessel contacted Marine Patrol the following day regarding the accident. 
  
  In the course of investigating the accident the officer stated that there is conflicting testimony regarding whether either vessel had navigational lights on. There is no conclusive fact the supports whether or not the navigational lights of one or both vessels were activated at the time of the collision. Neither party wanted for law enforcement to arrive before departing the scene making a "real-time" investigation possible. The state accordingly is not able to rule out if alcohol, another impairment or any other contributing factor is a component in this crash.
