AUSTIN -- The woman charged with DWI in a deadly Northwest Austin crash on Tuesday has a history of drunk driving.
Melissa Marshall's criminal record shows two previous drunk driving convictions -- one in Calfornia in 2006 and another from 2010 in Las Vegas.
Police obtained a search warant and drew Marshall's blood after the crash at U.S. 183 and Balcones Woods.
James and Lynne Clopton died in the crash.
Police say Marshall's car drove into the side of the Clopton's vehicle at the intersection but don't know which driver ran the red light.
Anyone who saw the crash is asked to call Austin police.
