RedactedNarrative: On June 21,2014 I Sgt. was contacted at 0300 by Palos Heights Police Department. The call was in reference to a boat accident that occurred at approximately 10:45pm on Friday the 20th on the Cal-Sag river just west of the Worth boat launch. Sgt. said there were several missing boaters unaccounted for and believed to be in the water. The collision was with a commercial barge heading eastbound up the river, while the recreational vessel was traveling westbound on the river. I responded to the scene and arrived about 0400, while at the scene I observed multiple agencies which responded and began the rescue efforts. I spoke with Sgt. who informed me that the recreational vessel involved in the accident had been moved from the center of the canal and tied to a tree on the north side of the channel to prevent the boat from sinking. I observed the boat approximately one quarter of a mile from the boat launch upside down and tied to the tree. The boat was three quarters submerged under water with just a small portion of the bow showing. The barge involved in the incident was tied to the southside of the channel and west of the launch. Capt. from the USCoast Guard was onboard and interviewing the Pilot of the commercial tug boat. The company (ARTCO) attorney''s arrived at the scene and would not allow me to interview the pilot of the tug boat, they said they would meet with the coast guard, give a written statement and provide me with the written statement. I received the written statements by fax from ARTCO on June 23,2014 at 3:11pm. 
  
  At approximately eight thirty, several hours after I arrived on the scene, the fire departments and divers left for the day and advised that if anything changed to contact them and they would return to assist. While in route to the scene I notified several of my officers. They arrived on the scene with two patrol boats and later one sonar boat arrived. We marked several locations in the water by sonar for the dive team to take a look at, I notified Palos Heights Fire District and advised Capt. that I thought we have several positive targets, he said he would return and evaluate the targets. 
  
  While waiting for the return of the dive team I had the boat moved from the north bank to the launch ramp by the coast guard patrol boat. I then phoned for a tow truck to remove the boat from the scene. At about 11:30am the dive team arrived and after reviewing the sonar information they decided to begin dive operations. At about 12:30pm Wes Towing arrived at the scene to remove the boat, I asked that the boat be raised slowly to look under the boat for any evidence pertaining to the accident. While raising the boat, CPO Thompson observed two deceased individuals underneath. With assistance of the fire department, large tarps were raised to limit the view from the public. The boat was raised and both individuals, one female identified by her drivers license, and one male identified by his drivers license were removed from the wreckage. Both were transported by Van Henkelum Funeral Services to the Cook County Medical Examiners Office. 
  The dive operation for the third victim was discontinued due to approaching weather, but we stayed on scene and continued our search until 4:00pm Saturday. On Sunday, we arrived on scene at 8:00am with two patrol boats and searched until 5:00pm that evening with no success. On Monday at 10:00am the body was recoverd down river, he was identified by his drivers license, was transported by Van Henkelum Funeral Service to the Medical Examiners Office. 
  The operator of the recreational vessel at the time of the accident is unknown, because there are no witnesses who saw them on the boat at the time of the accident or prior to the accident. 
   
  Two of the three on V1 had BACs over .08. Victim3 tested positive for alcohol and cocaine.  All victims drowned with trauma indicated as well.
