STAMFORD - The driver accused in a deadly hit-and-run in Stamford was charged with manslaughter today.

Police say Yolanda McDowell, 45, fled the scene of the accident on Woodland Avenue Sunday night.

Authorities believe that McDowell was high on drugs at the time of the collision and had no idea she had hit someone.

Officials say McDowell crossed over a double line and hit 70-year-old Margarita Gonzalez, who was crossing the street. The impact of the crash sent the victim under another vehicle as McDowell allegedly hit another car and drove away.

Police say they arrested McDowell about an hour later after a witness took down her license plate number.

Court records show that McDowell has 51 prior convictions. 

McDowell is being held on $250,000 bond.
