RedactedNarrative: On 9/15/2022, I, CPO, received notification from Vessel 2 [V2] regarding a boat accident his vessel was in when an unknown boat, Vessel 1 [V1], violated the "no wake" zone in front of River city Marina, causing an approximate $10,000 worth of damage to V2 Boat. On 7/23/2022, at approximately 11:30PM, V2 boat was tied up at his slip at River Side Mariana, located at 900 S. Wells St, Chicago, IL.
   
  Speaking with the owner of V2, he stated on the above date and time V1 was traveling southbound on the river at a high rate of speed, violating the "no wake" zone when it passed V2, which was tied up at its slip on the outside wall, resulting in V2  slamming into the wall. Damage was sustained to starboard side from bow to stern. V2 estimated the damage to be approximately $10,000. 
   
  V2 stated no one was on board and no injuries were sustained at the time of the accident. 
   
  I reached out to the harbor, local business, and CPD marine unit for any camera footage of the incident in attempts to identify V1. No video was able to be located.
