Victim of mystery explosion upset RI beach has reopened

NARRAGANSETT, R.I. (WPVI) -- The woman hurt in last week's mysterious explosion at a Rhode Island beach is speaking out again, this time exclusively to ABC News.

She says she is not happy that beach is back open, just days after she was injured in the strange event.

It started out as a beautiful day at the beach for Kathleen Danise, her two sisters, and her niece, Olivia.

The three women were getting ready to make a sandcastle with Olivia when, out of nowhere, "the sand exploded and my chair was sinking, and that's the last thing that I remember," Kathleen said.

She rocketed out of her seat, thrown in the air, and landed on a jetty. Her sisters screamed for help.

Now, a week after that event, Kathleen and her sisters are speaking out for the first time about their frustrating search for answers.

After the blast, investigators scoured the beach with metal detectors and K-9 units.

They say an electrical line they pulled from under the sand had nothing to do with the explosion because it was dead - no live electrical current was present.

The state's Department of Environmental Management has released a statement saying scientists are now collecting subsurface material for testing, which "will be

analyzed over the next few days."

Danise and her sisters insist that investigators are missing something, and that the beach is unsafe.
