National Park Service rangers are searching for two missing persons in two separate incidents that occurred over the last several days. A swimmer was reported missing in Gunsight Bay on Friday morning, September 21st. The 35-year-old Salt Lake City man from jumped off a wakeboat and was swimming toward a houseboat when he began to call for help. Members of the group he was with attempted to assist, but were unable to find him after he slipped beneath the surface. Early Monday evening, September 24th, a 911 call was received reporting a missing person in Padre Bay. During a localized windstorm with high wind and waves, a houseboat was pushed off shore and began to drift. A 58-year old Scottsdale man used a jet ski to seek help from a nearby houseboat. He picked up another person to assist with the drifting boat. Neither person on the jet ski was wearing a lifejacket or the kill-switch lanyard. As they motored toward the distressed houseboat, the jet ski lanyard fell off and activated the engine kill switch. The 58-year-old man jumped into the water to retrieve the lanyard. In the meantime, the passenger was able to restart the jet ski and motor to the distressed houseboat. Members of the group attempted a rescue but were unable to locate the missing man.NPS rangers, Glen Canyon National Recreation Area dive team, Kane County Sheriff’s Office and Utah State Highway Patrol dive team are assisting with both searches. The incidents are under investigation by Kane County Sheriff’s Office with the assistance of the National Park Service. All of the seven drownings this year could have been prevented if the victims had been wearing life jackets.
