ALVORD, Iowa (AP) — Authorities say a South Dakota woman died after being struck by a train in northwest Iowa. Lyon County authorities say deputies and medics were sent to the accident site a little before 7:30 p.m. Friday in Alvord. The Sheriff’s Office says it appeared that 32-year-old Savannah Flynn, of Marion, South Dakota, may have thought a southbound train was on the east set of parallel tracks when she tried to cross the west tracks and was struck. Flynn died at the scene. Authorities suspect alcohol consumption played a role in her death.
