(Portland, OR)  --  A Portland woman is dead weeks after she was critically injured in a hit-and-run crash.  Erin Brenneman died over the weekend after dealing with various injuries including a brain injury.  The 26-year-old was taking a walk on her break from the bakery she worked at when a driver hit her in the crosswalk at Southeast 80th and Pine and didn't stop.  Police are still looking for a suspect in the June incident and believe the vehicle was a dark-colored, mid-1990s pickup truck.
