A one-vehicle crash in the town of Egg Harbor late Tuesday evening killed one person and hospitalized another.  The Door County Sheriff’s Department was notified shortly before 9 p.m. of a vehicle crash on Heritage Lake Road, just north of the County E intersection.  When a Door County Sheriff’s Department deputy arrived at the scene shortly after 9 p.m., a 2002 Dodge pickup truck was found fully engulfed in flames.  The deputy assisted one person from the vehicle, lying outside the truck when a series of explosions occurred.  The Egg Harbor Fire Department arrived shortly after extinguishing the fire and found the second person deceased in the vehicle.  The crash survivor was transported and later flown to a Green Bay Hospital with undisclosed injuries.  The initial investigation indicated that the Dodge truck was northbound on Heritage Lake Road when the driver lost control of the vehicle, causing it to go into the ditch, where it struck a large tree and a utility pole.  The Brown County Medical Examiner’s Office is investigating the death. The Door County Sheriff’s Department is working with the Wisconsin State Patrol-Crash Reconstruction Unit to investigate the crash where it appears that speed and alcohol contributed to causing the crash.  No other information has been released at this time.
