7-month-old twins killed after Tennessee floodwaters ripped them from their father's arms

• 7-month-old twins in Waverly, Tennessee, are among more than 20 people who died in flash flooding over the weekend.
• Their father told News 4 Nashville that floodwaters ripped the twins from his arms as he tried to evacuate.
• Dozens of people are still missing following flash flooding in and around Humphreys County.

Seven-month-old twins died in deadly flooding in Tennessee over the weekend when rushing water ripped them from their father's arms, the family told local media this week.

Parents Matt Rigney and Danielle Hall told News 4 Nashville that their 7-month-old twins, Ryan and Raleigh, were swept away in flooding in Waverly, Tennessee, on Saturday as the family tried to evacuate.

Rigney told WSMV that water was flowing into the family's home when he tried to carry his 5-year-old, 1-year-old, and twins to safety.

"When the water hit and the room filled up, that's when I lost them. I lost all of them," Rigney said. "[Maleah] swam up like a big girl, and I grab her. I see Brayla across the room, and she's flapping her arms. I couldn't find the twins nowhere… It was the worst experience I've ever had."

A neighbor eventually pulled Rigney, the 5-year-old, and 1-year-old onto a roof, but the twins got lost in the water.

Hall, meanwhile, was also swept away by the flooding but was able to hold on to a tree.

Authorities found the bodies of the twins hours later, Rigney told WSMV.

Hall's cousin has since created a GoFundMe for the family in hopes of raising money to repair damage to their home and funeral expenses for the twins. It has raised more than $91,000.

At least 21 people died in flooding in and around Tennessee's Humphreys County over the weekend, and dozens of people are still missing, according to the New York Times.

The floodwater, which swept through a series of rural communities west of Nashville, destroyed homes, bridges, and cars in its path.
