Park dispatch was notified of an overdue six-person boating party on Lake Powell late last Saturday afternoon. A ranger soon found and rescued two people â Jim and Heather Brady of St. Pete Beach, Florida â from the shore at Padre Butte. The Bradys reported that their boat sank after taking on water during a wind storm. They were treated for hypothermia. An intensive search by boat and air was begun for the other four members of the group. The bodies of two of them â Katherine Prescott of St. Petersburg, Florida, and Mary Anne Taranto of Prescott Valley, Arizona â have been found; the other two â Terry Taranto of Prescott Valley and Robert Prescott of St. Petersburg â are still missing. The search is being conducted with the assistance of Utah State Parks and the Kane County and San Juan County sheriffâs departments. Investigation into the cause of the accident is ongoing. Weather is believed to have been a contributing factor.
