Subject 1 of Mesquite, TX Age 37,  and subject 2, of Rowlett, TX, Age 38, accompanied subject 3 (victim),male, on a boating trip on Lake Ray Hubbard. Subject 3 operated the vessel.  They launched the vessel at John Paul Jones Park boat ramp and drove the boat to party cove, an area of the lake located N. of I30 and E. of Dalrock Road.  Subject 3 drove a short distance (1/4 mi.) N. of I30 and decided to go for a swim. 

Subject 3 jumped from the boat and swam 10-15 yards from the boat and turned back. Subject 3 then asked to be thrown a lifejacket. Subject 1 could not locate a lifejacket quickly so subject 1 threw subject 3 two white floating boat bumpers. Subject 1 then drove the boat close to subject 3 and attempted to reach and grab his arm. Subject 3 went under the water and did not resurface. Subject 1 immediately called 911. 
Subject 1 had a difficult time leading responders to his exact location. Air One responded and led responding officers to his location, N. of I30 and E.of Dalrock Rd.
State Game Wardens, Air One, D.F.D. Marine One, and D.P.D. searched the area where subject 3 was last seen until darkness. D.P.D. placed an orange bouy in the water where subject 3 was last seen.
D.P.D. escorted the vessel containing subject 1 and subject 2 back to John Paul Jones Park boat ramp.
