The boyfriend of a Florida woman who was killed in a horrific alligator attack says he is “falling apart” as he mourns the loss of the woman he hoped to build a future with.

Brittany Clark, 31, was attacked while swimming in the Econlockhatchee River at Little Big Econ State Forest. Her boyfriend, Chance Allison, 30, desperately tried to rescue her after the alligator ambushed her in the water.

Clark suffered catastrophic injuries during the attack. Authorities said one of her arms was torn off, while the other was left barely attached. She survived long enough to be taken toward a hospital but later died from her injuries.

The couple had been swimming with Clark’s roommate, Jayden Hernandez, when the alligator emerged from the murky river.

Days after the tragedy, Allison shared an emotional message on Facebook, saying he was still struggling to come to terms with what had happened.

“I’m just still in disbelief of what took place,” he wrote.

“We had so many things planned out and memories to be made. You were such a special person and did not deserve to go out in such a way.”

He also promised to care for Clark’s beloved pets.

“I love you and don’t worry about Shady and Hokie. I’ll take care of them forever.”

Allison said he is organizing a celebration of life in Clark’s honor and thanked everyone who had reached out with messages of support.

“They really have helped me hold together just as much as I’m falling apart,” he wrote.

Clark’s father, Robert Clark, said he learned about the attack while speaking on the phone with Hernandez, who described the terrifying moments as they unfolded.

According to Robert, Hernandez told him she and Allison were desperately trying to keep Brittany alive while waiting for first responders to arrive.

“I received a call on Sunday from Brittany’s roommate Jayden and she was explaining as it was happening,” he told the New York Post. “They were trying to keep her alive and waiting for the authorities to show up.”

The heartbreaking news came just days after the family had already begun mourning another devastating loss. Robert said his 80 year old mother, Barbara, had died the previous Thursday.

Emergency calls released after the attack revealed the panic as Allison and Hernandez begged for help while trying to save Clark.

During the 911 call, Hernandez described Clark’s injuries as “horrible.”

“One of her arms is completely off and the other one is like attached barely,” she told the dispatcher. “Hurry. She’s losing a lot of blood. We need to stop the blood.”

Screaming and crying can be heard throughout the call as the group struggled with the alligator.

At one point, Allison shouted, “Both her arms, both her arms are off,” before Hernandez clarified that one arm was still “hanging by a thread.”

When the dispatcher asked where the other arm was, she replied, “Gone.”

Allison also told the operator that he and a friend had managed to pull Clark from the river.

“We’re far off the trail, we’re off of a little launch area by the river. We need help now!” he said.

The dispatcher responded that a helicopter might be arriving and instructed them to try to signal it if they saw it.

According to the medical examiner’s report, the alligator grabbed Clark by the arm before performing a “death roll,” a violent spinning maneuver that alligators and crocodiles use to overpower their prey by dragging them underwater.

The report said Allison grabbed the alligator in an attempt to force it to release Clark, and both he and the animal went underwater during the struggle.

He briefly managed to free one of Clark’s arms before the alligator latched onto the other.

The report added that Allison tried to bring Clark back to shore, and once the alligator finally released her, he immediately began CPR while someone else called 911.

As investigators continue examining the fatal attack, officials with the Florida Fish and Wildlife Conservation Commission captured two large alligators in the area, measuring approximately 13 feet and 12 feet long. The investigation remains ongoing.
