RedactedNarrative: On Sunday 07/12/2020 at approximately 1823 hours, at the Scorpion Bay Marina slip A37, located within the Lake Pleasant Regional Park, Maricopa County. The four occupants on vessel 1 were going to go swimming behind the boat in the slip. In an attempt to recover a floatie which was moving away from the swim platform Victim2 stuck his leg into the water and felt a shock, at about the same time his brother Victim1 jumped into the water and began convulsing. In an attempt to assist Victim1, his fiancé entered the water and began convulsing, she was recovered with minor injuries by Victim2 and subject1. Trying to help his brother, Victim2 entered the water and also began convulsing. Subject1 an adjacent boat owner responded to the yelling and entered the water when he began convulsing, others were able to help him out of the water. 
  
  With the assistance of others, Subject2 was able to remove Victim2 from the water onto the swim platform and began rendering aid. 
  
  Victim1 and Victim2 who had entered the water behind Victim2''s boat were observed to begin shaking/convulsing appearing to be electrocuted, succumbing to their injuries and died. Subject3 and Subject1 who attempted to render aid and were pulled out of the water reported to feeling electricity in the water. 
  
  As a result of this incident, our first priority in the investigation was to determine ongoing safety for the public, employees at the Scorpion Bay Marina, and Sheriff''s Office personnel investigating. 
  So the night of the incident, along with the assistance of APS, we were able to shut down electricity to dock A. Arrangements were made by Scorpion Bay Marina to provide generators to those living in houseboats in the affected area so they could have air conditioning. One resident had a medical condition requiring equipment ran by electricity, so a generator was provided. This allowed for a safe scene for Lake Patrol Detectives and Divers during the body recovery and inspection of the electrical components.  
  On Monday morning, LP Detectives with the assistance of The City of Peoria Electrical Inspector, and a Commercial Electrician who specializes in Marina construction were able to determine the Scorpion Bay Marina''s electrical infrastructure was operating properly and safely. 
  
  The second phase of the investigation was to determine the source of the electricity that contributed to the drowning of Victim2 and Victim1. 
  
  Under the supervision of the electrical professionals, LP Detectives were able to conduct multiple experiments and ultimately recreated the circumstances which placed electrical voltage into the water. This result was isolated to the electrical system of the victim’s watercraft only. No other boats or slips were affected.   
  
  The victim’s boat had an electrical connection system which was not compatible with the marina’s receptacle. Electrical safety features were bypassed by the intentional and improper modification of the boat’s electrical connection system. This resulted in electricity being discharged into the water around the swim platform, which is where the victims entered the water. 
  
  The investigation is ongoing, following up on additional leads. Further Details will be released at the completion of the investigation.
