RedactedNarrative: ON FRIDAY, JULY 23, 2021 AT APPROXIMATELY 5:33PM, I (OFFICER 1) AND OFFICER 2 WERE WORKING FOR THE GENEVA LAKE LAW ENFORCEMENT AGENCY IN MARKED POLICE BOAT UPON THE WATERS OF GENEVA LAKE. WE RECEIVED A CALL FOR SERVICE NEAR LINN PIER, PIER 749, FOR A POSSIBLE BOAT CRASH INVOLVING TWO PWC'S. WE RESPONDED TO THE AREA AND SAW FOUR PWC'S STATIONARY. THERE WERE 5 JUVENILE FEMALES PRESENT AND ONE MALE IDENTIFIED VERBALLY AS V1 OWNER. IT WAS DISCOVERED THAT A BLACK 11'6" KAWASAKI HAD COLLIDED INTO A BLACK SEA DOO GTI130. OPERATING THE KAWASAKI WAS V2 OPERATOR, WITH V2 PASSENGER. OPERATING THE SEA DOO WAS V1 OPERATOR, WITH V1 PASSENGER. V1 PASSENGER STATED SHE WAS SUFFERING FROM SHOULDER PAIN AND WAS CRYING. WE IDENTIFIED V1 OWNER VERBALLY AND ASKED WHERE HIS PIER WAS. HE STATED IT WAS IN THE AREA OF PIER 744. WATER SAFETY HAD BROUGHT V1 PASSENGER ONTO THEIR BOAT AND WE ASKED ALL REMAINING PARTIES, INCLUDING WATER SAFETY, TO PROCEED TO PIER 744 SO WE COULD GATHER MORE INFORMATION. WATER SAFETY INFORMED US THAT V1 PASSENGER WAS SUFFERING FROM A HEAD TRAUMA AND THEY WERE GOING TO BRING HER TO LINN PIER, PIER 749, AND REQUEST AN AMBULANCE. WHEN WE ARRIVED TO THE PIER, V1 PASSENGER WAS SUFFERING FROM SHORT TERM MEMORY LOSS, APPEARED TO BE IN DISTRESS, AND CONTINUED TO HAVE SHOULDER PAIN. V1 PASSENGER WAS UNSURE WHERE SHE WAS, WHY SHE WAS ON GENEVA LAKE, WHERE HER PARENTS WERE, OR WHERE HER FRIENDS WERE. I SPOKE WITH V2 PASSENGER AND SHE INFORMED ME THAT HERSELF AND ALL OTHER PARTIES INVOLVED HAD NOT SUSTAINED ANY INJURIES. SHE VERBALLY CONFIRMED WITH ME THAT THEY ALL HAD THEIR BOATERS SAFETY LICENSES. SHE GAVE ME A BRIEF DESCRIPTION OF HOW THE ACCIDENT HAPPENED.  V1 PASSENGER WAS TRANSPORTED TO LAKELAND HOSPITAL IN ELKHORN, WI, WALWORTH COUNTY VIA LAKE GENEVA AMBULANCE WITH V2 OWNER.
