A high-speed chase in South Florida between police and a gunman suspected of shooting two women on Wednesday ended in a horrific highway crash that killed an innocent driver.

Broward County authorities said the gunman was discovered dead at the crash site on U.S. 27 after an hour-long standoff with dozens of deputies and SWAT teams, the Miami Herald reported.

"We just saw this car speed by, we said 'Oh my God, this is crazy.'" Ortiz said.
