RedactedNarrative: On Tuesday July 12, 2016 a 33 year old hispanic male was reported by witnesses to have jumped off of a moving 18 ft Bayliner boat just east of the Callville opening on Lake Mead within the Boulder Basin.  Sometime after jumping from the vessel the man stopped breathing and the two other occupants of the boat grabbed him and brought him back to Callville Bay where CPR was started.  Rangers, Medic 42, Community Ambulance, and Mercy Air 7 all provided care to the patient who was pronounced dead at 1921 hours after 45 minutes of CPR and advanced medicine care.
