RedactedNarrative: On 09/11/2021 at approximately 2130 hours we began the investigation of a two vessel accident that resulted in us responding to an unattended vessel doing circles at speed in Grass Lake. We later learned the operator of the unattended vessel doing circles had been transported to the Port of Blarney in Antioch, 27843 W. Grass Lake Rd. Antioch 1160002. 
  Deputy obtained a statement of this operator who basically said in summary but not verbatim that he had left Fox Lake on his way through Nippersink Lake with the intention of going to Blarney Island Tavern in the center bf Grass Lake. 
  While northbound through Grass Lake he attempted to turn left towards the channel that leads to the state park when an unknown and unseen vessel had struck him head on ejecting him from his boat. An uninvolved vessel picked him up and transported him to Port of Blarney, subject performed a PBT on the subject and he showed .00 result. 
  While awaiting transportation to arrive and take this operator home we learned from Fox Lake Fire Department personnel that the second boat had been tied up at Restaurant, 200 Forest Ave. Fox Lake II 60020. They advised further that the operator had fled the scene but someone present at had told them the operators name. 
  Deputy and I traveled to and located-vessel number two. While present at restaurant we learned McHenry County Deputies were on their way to a home in in unincorporated McHenry, to assist rescue with victim's of a boat accident.
  
  I later spoke by telephone with Deputy who stated that rescue hadtransported operator 2 and his two twin 7 year old sons to Northwestern McHenry Hospital. She stated she didn't see obvious signs of impairment on him and that he admitted to drinking one alcoholic ·drink at the Sunset Grill with dinner. He told her he panicked after the accident and fled.
  
  I later traveled to McHenry Hospital at approximately 0100 hours 09/12/21 and located Operator 2 and his sons in emergency room
  
  He advised he had been traveling south bound across Grass Lake when a collision occurred with another vessel.
  He advised he had left Grille and was headed towards Marina on Pistakee Lake when the collision occurred. He advised he never saw the other boat and decided to go. When asked why he didn't seek rescue for his obviously injured children, one had bled heavily on the boat, he stated he didn't think it was that bad. 
  I asked hospital staff if they had drawn blood on operator 2 and was advised they had not. There were no obvious signs of intoxication while observing him and it was approximately three and a half hours since the accident. I took no further action.
  n summary, Unit was dispatched to a boat going in circles in the middle of Grass Lake. Unit located a blue and white Bayliner with Illinois registration, going in circles, unoccupied with heavy damage to the starboard side of the bow and a broken-ou.t windshield. Rescue was notified, and Units  began searching the area for the boat operator. Shortly after, Antioch Rescue arrived at our location. Unit was notified the boat operator was picked up out of the water and taken to Port of Blarneys. 
  
  Unit and Antioch Rescue stayed with the unoccupied boat to make attempts to stop it, while unit relocated to Port of Blarneys to locate the boat operator. Unit arrived at Port of Blarneys and located the boat operator. Victim, stated he was traveling north on Grass Lake near the center marker buoys and was making a left turn into a marked channel near Blarney Island. Operator 1 stated that "he hit a boat, or a boat hit him" that was coming out of Blarney Island'. He denied having any alcoholic beverages-and consented to give a breath sample, which indicated negative results: (.000). He refused medical attention at that time. He was given a shirt and sweatshirt to keep warm. A taxi service was called for him for a ride home in Lake Villa.

Operator 2 did not notice that his friend had to throttle down to avoid getting hit and didn't have time to react to avoid getting hit. He also stated that he didn't know the operator of the boat that hit him went overboard into the water until his friend witness told him.
