Heartbreaking photos emerged Tuesday of the Florida woman fatally mauled by an alligator while hiking with her boyfriend over the weekend.

Native Californian Brittany Clark, 31, was seen smiling in a sleek red slip dress just months before Sunday’s trip turned tragic when the couple went for a swim in the Econlockhatchee River at Little Big Econ State Forest.

A giant, 12-foot gator lunged from water and clenched its jaws onto Clark as she was in just three feet of water, ripping one arm “completely off.” according to officials.

“They were hiking and they just stopped to swim,” Florida Fish and Wildlife Conservation Commission spokesperson Chad Weber told reporters at a press conference on Monday.

“She was bitten on both of her arms. The boyfriend was the one that made the phone call. He was trying to get her from the alligator’s mouth, and on the way to the hospital she did pass away from her injuries.”
