BRANSON, Mo. (AP) - The country-and-western tourist town of Branson, Missouri, mourned Friday for more than a dozen sightseers who were killed when a duck boat capsized and sank in stormy weather in the deadliest such accident in almost two decades.
Divers found four more bodies in Table Rock Lake, bringing the death toll to 17, including nine people from the same family and the crew member who was steering the amphibious vessel. In their initial assessment, authorities blamed thunderstorms and winds that approached hurricane strength.
"Branson is a city full of smiles," Mayor Karen Best said. "We have so much fun here. But today we are grieving and crying."
Trisha Ayers was among the mourners who stopped to pay their respects at a parked car that was covered with flowers because it was believed to belong to a dead tourist.
Ayers said she understood how the boat got caught on the lake because the weather on Thursday evening changed in 10 minutes from sunshine to gale-force winds that bent traffic signs.
"I hope it won't tarnish Branson," she said with tears in her eyes. "About 80 percent of our income comes from tourists. We love them."
The risk of heavy weather was apparent hours before the boat left shore.
The weather service station in Springfield, about 40 miles (64 kilometers) north of Branson, issued a severe thunderstorm watch for its immediate area Thursday, saying conditions were ripe for winds of 70 mph. It followed up at 6:32 p.m. with a severe thunderstorm warning for three counties that included Branson and the lake. The warning mentioned both locations. The boat went down about 40 minutes later, shortly after 7 p.m.
"When we issue a warning, it means take action," meteorologist Kelsey Angle said.
Suzanne Smagala with Ripley Entertainment, which owns Ride the Ducks in Branson, said the company was assisting authorities. She said this was the company's only accident in more than 40 years of operation.
Twenty-nine passengers and two crew members were aboard for a pleasure cruise. Seven of the 14 survivors were hurt when the vessel went down. At least two children and two adults were still hospitalized Friday afternoon. The captain survived, authorities said.
Brayden Malaske, of Harrah, Oklahoma, boarded a replica 19th-century paddle-wheeler known as the Branson Belle on the same lake just before the storm hit.
At the time, he said, the water seemed calm, and no one was worried about the weather.
"But it suddenly got very dark," he recalled.
In a short video taken by Malaske from the deck of the Belle, the duck boat can be seen wallowing through the choppy, wind-whipped lake, with water only inches from its windows. Dark, rolling waves crash over its front end. The footage ends before the boat capsizes.
Later, people on Malaske's boat saw a duck boat passenger "hanging on for dear life" to the paddle wheel of the Belle, he said.
The mayor identified the crew member operating the boat as Bob Williams, known informally as "Captain Bob."
"He was a great ambassador for Branson," Best said. "He was at every event. He knew everyone. He was always promoting Branson."
Authorities did not publicly identify the dead but said they included a 1-year-old child.
A survivor from the family who lost nine relatives said the captain told passengers not to bother grabbing life jackets.
Tia Coleman told Indianapolis television station WXIN that she and a nephew were the only survivors among 11 relatives aboard the boat. She said she lost all her children, but she did not say how many.
Coleman said the captain told passengers that they would not need life jackets. By the time of the accident, "it was too late."
An email message seeking comment from Ripley Entertainment was not immediately returned.
Tracy Beck, of Kansas City, Missouri, said she recalled the family members waiting in line and blamed a possible ticket mix-up for them ending up on the ill-fated boat. She said the ticket taker realized after they stopped for a photo that they should have boarded at a different location and assigned them new tickets.
Named for their ability to travel on land and in water, duck boats have been involved in other serious accidents in the past, including the deaths of more than 40 people since 1999.
Five college students were killed in 2015 in Seattle when a duck boat collided with a bus. Thirteen people died in 1999 when a boat sank near Hot Springs, Arkansas.
"Duck boats are death traps," said Andrew Duffy, an attorney whose Philadelphia law firm handled litigation related to two fatal duck boat accidents there. "They're not fit for water or land because they are half car and half boat."
Safety advocates have sought improvements and complained that too many agencies regulate the boats with varying safety requirements.
The boats were originally designed for the military, specifically to transport troops and supplies in World War II. They were later modified for use as sightseeing vehicles.
A full investigation was underway, with help from the Coast Guard and the National Transportation Safety Board. Stone County Sheriff Doug Rader urged anyone with video or photos of the accident to contact authorities.
The agencies were briefing Missouri's two senators on the accident. Democrat Claire McCaskill said she would look into possible "legislative solutions," while Republican Roy Blunt called it a "tragedy that never should have happened."
The sheriff said Thursday that two duck boats were on the water at the time of the storm. Both were headed back to land. One returned safely. The other did not.
Divers quickly located the sunken vessel, which came to rest on its wheels on the lakebed. Authorities planned to recover it at some point in the next few days.
The boat sank in 40 feet (12 meters) of water and then rolled on its wheels into a deeper area with 80 feet (25 meters) of water.
The Ride the Ducks tour begins in downtown Branson, where the vehicles take passengers on a tour while the captain cracks jokes and points out landmarks. Eventually, the boats pull up to the lake and slowly enter the water with a small splash.
After a few minutes on the water, the vehicles return to land and to their home base, which features a store selling candy and souvenirs.
Branson, about 200 miles (320 kilometers) southeast of Kansas City, is a country-themed tourist mecca built on a reputation for patriotic and religious-themed shows in numerous theaters.
Table Rock Lake, east of Branson, was created in the late 1950s when the Corps of Army Engineers built a dam across the White River to provide hydroelectric power to the Ozarks.
