One person was killed and five people were injured Monday in an explosion on a boat at the Lauderdale Marina near the popular 15th Street Fisheries restaurant in Fort Lauderdale. “Five people have been transported to local hospitals for treatment, three of whom are suffering from traumatic injuries,” said Fort Lauderdale Fire Rescue spokesman Frank Guzman. A sixth person was reported missing and later found dead in the water by the Broward Sheriff’s Office, Guzman said. The first 911 calls came in just before 6 p.m.
