%%file news.dat (CNN)Betsy Williams recalls being awoken just after 4:30 a.m. Friday by what sounded like gunfire from an automatic weapon.

After Williams called 911 and police cordoned off Second Avenue in downtown Nashville, a "computerized message" from a parked RV captured her attention.

"Evacuate now," Williams remembers the female voice saying -- over and over again.

Williams told CNN hours after the vehicle exploded, injuring three, that she and wife Kim clearly heard another message emanating from the RV. It was a countdown.
