 An Auburn man, Anthony Jokinen, was killed yesterday in a motorcycle crash on the Vietnam Veterans Memorial Bridge. Police tell the Sun-Journal speeding and impairment contributed to that fatal crash. And yesterday afternoon, a collision killed Troy Tangway of Saco. Police say a car driven by Emily Rea was trying to make a left turn and a pickup driven by Sean Foley of Lyman couldn't stop in time. Tangway was a passenger in Rea's vehicle.
