After deadly Tennessee floods, search goes on for the missing as survivors recall "the scariest thing ever"

Catastrophic flooding killed at least 21 people west of Nashville, Tennessee, after record-breaking rainfall washed away homes and roads Saturday. More than 20 people are still missing.

"It is heartbreaking to see," Governor Bill Lee said, calling the aftermath of the flooding a devastating picture of heartache. "Tremendous loss of life, a number of missing people on the ground, homes washed off their foundations, cars strung around their community," Lee said.
