The search for 44-year-old Billy Coile of Mandeville continued on Tuesday. According to his brother-in-law, Richard Lyons, Coile is a father of two, husband and avid fisherman. “If Billy wasn’t at home with his family or at work, he was on the water," Lyons said. He borrowed a friend's boat to go fly fishing on Saturday, and the boat was found on Sunday morning near mile marker 23 under the Causeway bridge. His truck was located nearby at the Mandeville harbor. The Louisiana Dept. of Wildlife and Fisheries is leading the search with the assistance of the St. Tammany Sheriff's Office. The Coast Guard suspended its search for Coile on Sunday. “There was such an app on his phone, and the last time that it pinged, or gave his location, was around 6:30pm on the night that he went fishing," Lt. Joel Cromp said, "So, that’s kind of what we’re working off of there. In between where that ping was and the location where his boat was found.”
