RedactedNarrative: On 05/27/2018 at approximately 17:30 Sgt. received a call from Lake County Marine Unit concerning a boat accident on Nippersink Lake.  Information provided indicated the boat accident occurred at approximately 14:15 and two young females were injured and currently at Vista hospital in Waukegan. Sgt. and I CPO were on boat patrol on the Chain O Lakes at the time of the call and proceeded to Jet Funn rentals on Nippersink lake to gather more information.
  
  After speaking to the owner of Jet Funn I determined one of his personal watercraft had been in the accident.  The watercraft in question was rented out to someone other than the operator. The owner informed me the watercraft had been returned by another individual who quickly left to go with the girls to the hospital. 
  
  The watercraft had scrapes and grooves extending from bow to stern on the front port side with purple paint transfer.  The fiberglass on the port side foot guard was crushed in an area approximately 8in wide.
  
  Witnesses who were at Lake Front Park said a little after 2:00PM they saw the two girls on a blue jet ski, (vessel #2) traveling east, making a turn in front of a purple jet ski,  being operated by a middle aged male traveling south (vessel #1).  As vessel #2 crossed in front of vessel #1, vessel #1 hit a wave and struck vessel #2.  The impact overturned vessel #2 and both girls were thrown into the water. From this point no one knows what happened to vessel #1. Witnesses said the accident happened about 75 meters from the shore line.  
  
  Hearing the accident renter ran into the water, swam to his daughters, and with the help of another person on a personal watercraft transported them back to shore.  Renter said as he was entering the water he heard a lady say she was calling 911.  Not seeing any sort of emergency vehicle upon getting his daughters to shore he transported them to Vista Health Center in Lindenhurst. Operator of vessel #1 left the scene without reporting the accident.
  
  CPO took statements at the hospital.  The only thing Operator2 could remember is they were traveling approximately 30mph when they were struck on their port side.  Next thing she remembers is she was in the water.  Occupant was in shock and could not recall any details of the accident.
