  On 09/02/2019, at about 10:36 p.m., this vessel was drifting on Lake Washington at the 7700 block of West Mercer Island, located near Mercer Island, WA in King county.
  
  According to Law Enforcement, on this date and time, Officers were dispatched to this location for a boat playing loud music off the shore of Mercer Island.  When they arrived, they could hear and see a boat in the water about .25 miles from shore playing loud music.  They attempted to hail the occupants of the boat using the patrol vessel’s PA and shining the spotlight on them.  They did not receive a response.  The boat was slowly drifting south from this location.
  
  At about 11:03 p.m., other Officers were dispatched to assist with the noise complaint.  They arrived on scene at about 11:29 p.m.  There was no boat traffic in the area.  Officers observed this vessel floating with the navigation lights on playing loud music.  Officers tied off to the vessel and noted that there was no one on board.
  
  Officers observed multiple open “hard seltzer” cans inside the vessel as well as personal items identified as belonging to Operator and Occupant.  The vessel had the key in the ignition with the accessories turned on.  Operator’s phone was on playing music.  The engine was off but was still warm to the touch.  The interior of the vessel was wet to suggest people were getting in and out of the water.  There was a type 4 throwable on the captain’s chair that was also wet.  There was also a cooler filled with full “hard seltzers” along with a backpack with canned alcoholic beverages.
  
  It appeared that there had been 2 occupants previously aboard the vessel, Operator and Occupant, but were nowhere to be seen.  A search of the shoreline and surrounding water was completed using SLIR, Sonar, and spotlight.  They were not able to locate anything or anyone.  Seattle PD Harbor Patrol arrived to help search the area.  The US Coast Guard was also notified and dispatched a helicopter to the scene.  The helicopter performed a search with negative results.  The depth of the water in the surrounding area ranged from 40’ to 120’.  The weather was clear, water was calm, with only a light breeze.  
  
  Officers went and checked both Operator’s and Occupant’s residences, both were un-occupied.  Operator’s truck and trailer were located at the Gene Coulon boat launch in Renton.  There was no one around the vehicle when it was located or during the entirety of the call.  The vehicle was impounded for safekeeping by the Renton PD.  The vessel was towed to the Mercer Island PD boat dock and secured.  The personal items belonging to Operator and Occupant were secured at the station.
  
  On Monday, 9/30/2019, two bodies were located in 110’ of water about a mile off the shores of Mercer Island.  On Tuesday, 10/1/2019, the two bodies were recovered by divers and confirmed to be those of Operator and Occupant.  The cause of death for both victims was determined to be accidental drowning.
