Loved ones of Colleen Monfore believe she died of a medical issue during a dive off the coast of Indonesia, not by shark attack.

The body of a South Dakota woman is believed to have been located after an Asian fisherman discovered human remains inside of a shark.

"I thought it had swallowed plastic or a fishing net. It was cut open to find the problem and inside there were the remains of a woman," the fisherman who caught the shark said.
