Police: 2 teens missing in N.J. lake presumed dead MOUNT OLIVE, N.J. Authorities say the search for two teenage boys believed to have fallen through the ice into a northern New Jersey lake has become a recovery mission. State Police divers continued to search Tuesday morning for the boys, who went missing on Budd Lake in Mount Olive Township. The effort had switched from a search to a recovery mission earlier in the day. Morris County First Assistant Prosecutor Tom Zelante said a police fanboat has arrived, CBS Station WCBS New York reported Tuesday. "There will be a diver and another person with the boat and they will begin their maneuvers and continue to search and recover for these teenage boys out there," he said. Police received reports of screams for help coming from the lake around 6:20 p.m. Acting Morris County Prosecutor Fredric Knapp said two residents went out on a boat, but failed to find anyone. Rescuers broke through more than 100 feet of ice and a state police helicopter illuminated the scene before the search was called off Monday night. Mayor Robert Greenbaum believes the two boys may have been ice fishing, WCBS reported. "It's not something which is guarded," he said. It's a natural lake and people use the facility, the lake to do whatever is appropriate during the season and I can tell you that's probably what happened. Clyde Schimanski, the father of one of the boys, told WCBS reporter Sean Adams that he thinks his son and the other boy were on their bikes: "There were people saying Clyde was out there and he seen the kid go through the ice and Clyde went to save him on his bicycle and then they both went in. And then people from the shore heard them screaming.
