RedactedNarrative: On 03/09/2021 at 1043 hours, Maricopa County Sheriff''s Office Lake Patrol units responded to a collision involving two vessels on Bartlett Lake east of Rattlesnake Cove near the “reef” buoy line, on the west side of the lake. 
  
  According to witnesses and parties involved, Vessel #2 was traveling south on the lake, obeying the traffic pattern (counterclockwise), along the “reef” buoy line. Vessel #1, which was occupied by one male subject, was traveling north. As Vessel #1 was traveling north, it was violating the traffic pattern on the lake, and was traveling on the port side of Vessel #2. 
  
  As Vessel #1 came closer to Vessel #2, Vessel #1 made a sharp turn to the left, directly in front of Vessel #2. Vessel #2 stuck Vessel #1 on the starboard front side and went over the Vessel, striking the sole occupant who was sitting in the operator’s seat. 
  
  After being stuck by Vessel #2, the operator of Vessel #1, was ejected into the water. After Vessel #2 struck Vessel #1, it launched up into the air and landed back on the lake. 
  
  From the impact of the landing on the lake, both occupants on Vessel #2 were also ejected of out of the Vessel. The sole occupant on Vessel #1, succumbed to the injuries he sustained. The occupants on Vessel #2 were evaluated at the Jojoba boat ramp by Rural Metro Fire Department and refused further medical treatment. 
  
      Due to the amount of damage to both Vessels and the totality of the circumstances, it was determined that both Vessel were on plane and traveling at speeds of 40 miles per hour or more.
  
      MCSO Lake Patrol Detectives responded to the scene and assumed the investigation at that time. 
  
      My MCSO body worn camera was activated during my contact with parties involved.
