(FOX NEWS) -- An Army Reserve member drowned on Saturday as he tried to save his fiancée’s young daughter at a lake in Texas.
Brandyn Mitchell, 25, was pulled from Lake Ray Roberts around 4:30 p.m. on Saturday, The Dallas Morning News reported.
Mitchell, of Valley View, was helping Keira, the 6-year-old girl, get back onto a flotation device when, as he told her to hold on, "slipped," his fiancée, Angelia Herrera, told the Fort Worth Star-Telegram.
The water at the Isle du Bois beach is reportedly 6 feet deep.
"He wanted to be a hero, not just once but every chance he could," Herrera told the news outlet. "Shortly put, he was an amazing man and I am lucky to have known him."
Mitchell, who was reportedly a father to three children and Keira, served in the Tennessee Army National Guard for six years after high school.
His mother, Stacey Thompson, told the Star-Telegram that Mitchell "could swim like a fish," which is why she "can't understand" how he drowned.
Thompson added that "everybody had a good time” whenever her son was around.
Mitchell's fiancée said he was enrolling in college with plans to become a firefighter.
