MAGNA — Two 25-year-old duck hunters died after their boat capsized on the Great Salt Lake while they were heading back to shore, authorities said.

Logan Hardman of West Jordan and Chad Tohinaka of Salt Lake City died Saturday night, while a 24-year-old friend managed to swim safely to shore, said Unified Police Department Lt. Justin Hoyal.

The trio began hunting early Saturday afternoon and their boat overturned a few hours later after the weather suddenly turned bad, Hoyal said. Waves swamped the boat, causing it to capsize and plunge all three men into the 47-degree water.

The third man swam about a half-mile to shore for help, while the bodies of the other two were found floating in the lake late Saturday night.

Hardman's brother, Matt, told The Salt Lake Tribune ( ) that the two victims had been friends since first grade.

"They did everything together," he said. "And they both ended up going together."

Matt Hardman said all three men in the boat were very experienced hunters.

"It's something they did all the time and loved," he said, adding his brother leaves behind a wife and two children, 3 and 1.

The third man, whose name wasn't released, was treated at the scene for minor injuries.

He was walking on a frontage road when Great Salt Lake Marina State Park harbormaster Dave Shearer picked him up in a truck.

"He was cold but with it (mentally)," Shearer told The Tribune. "He said they had capsized and they stayed with the boat for 15 minutes before he told them he was going to swim in for help and the other two were going to stay with the boat. As soon as he told me the boat had capsized, we went back out to look for them."

Hoyal said at least one personal flotation device was in the boat, but he didn't know if anyone was wearing it.
