An 81-year-old woman was pulling into a parking space at a South Florida bank when she stepped on the gas pedal and slammed her car into a man and his mother.
Police say the incident happened at a Bank of America on Congress Avenue in Boynton Beach Monday afternoon.
A Toyota Camry allegedly went over the concrete parking stop and struck Diane Power, 63, pinning her against the wall.
Her son, 32-year-old Timothy Power tried to run but was pinned underneath the car after it bounced off the wall of the bank.
The driver, identified as Louise Szakacs, was finally able to stop the car after it traveled back into the parking lot.
Both victims were taken to Delray Medical Center in Delray Beach with critical injuries. Police say one of Diane Power's legs had to be amputated.
Szakacs was taken to JFK Medical Center as a precaution.
Investigators haven't determined if the driver failed to brake or confused the gas pedal for the brake pedal.
Citations are pending the outcome of the investigation.
