EDEN, N.C. (WTVD) — A family on Thursday demanded action after their loved ones were killed in a tubing accident in Eden, North Carolina.

It happened back in June on the Dan River.

Four of the nine were found by construction workers 11 hours later. They were “hanging onto various items.”

Five people died, including Bridish Crawford, Antonio Ramon, Teresa Villino, 14-year-old Sophie Wilson and 7-year-old Isiah Crawford. Teresa Villino’s unborn child also died, the family said Thursday.

Other family members, speaking from Indiana on Thursday, said they are suing Duke Energy. They called on the company to modify or eliminate dams altogether.

The family contends that Duke placed warning signs near the dam two days after the drownings.

Duke Energy previously said there were two signs posted before the accident. The company installed three new signs afterward.
