UPDATE: Investigators with the Coast Guard and National Transportation Safety Board are investigating a duck boat accident that killed 17 people in southern Missouri.

Coast Guard Petty Officer Lora Ratliff says the agencies are working “side-by-side” to determine what caused the Ride the Ducks boat to sink Thursday night in Table Rock Lake in the Branson area. NTSB spokesman Peter Knudson says its investigators are arriving Friday.

Authorities are releasing few details, including whether the people aboard were wearing life jackets. The NTSB and Stone County Sheriff Doug Rader are urging anyone with video or photos of what happened to provide them to authorities.
