There are new developments in the Napa killing of two teenage women. Police have arrested a Vallejo man they say pulled the trigger last Saturday night, possibly in a drive-by. A 19-year-old mom with a baby at home, and a 17-year-old were shot in a neighborhood. One died at the scene in the arms of a witness who tried to help, the other at the hospital. Police also arrested two 19-year-old Santa Rosa women yesterday on charges of aiding in a felony. No word yet on a motive.
