RedactedNarrative: On September 7, 2019 I was notified by SALECS that a fisherman had gone overboard from a rental boat from the Alcova Marina and was unable to be located in Fremont Canyon on Alcova Reservoir.  With this information, I made my way from Casper to Alcova to assist with the search of the missing angler.  Upon arriving I was briefed by the sheriff's office as to the presumed location and given a description of what the individual was last wearing.  I then launched our patrol boat with game warden to begin searching for the victim.  On our way to Fremont Canyon, we performed a stop on the rental boat that was coming back to the marina.  The purpose of this stop was to check to see that safety equipment was on board the rented boat.  During this watercraft stop, we located several type III life jackets available along with a type IV throwable device accessible and in plain view.  The contact was then broken and the rental boat was instructed to return to the marina.  Upon reaching Fremont Canyon warden and I began grid searching the area where the victim had entered the water and was last seen using our sidescan sonar and spotlights to scan the shoreline.  During this search, another boat recovered a hat, work boot, empty whiskey bottle and some beer cans all presumably belonging to the victim.  After a few hours of unsuccessfully searching, our work was stopped until the following morning.  Our search continued in conjunction with the Natrona County Sheriff's Office on and off for the next 12 days.  On September 19th, I was notified by the sheriff's office that he had found victim.    To date I am awaiting toxicology results and an official cause of death from the coroner.
