A 53-year-old Lincoln woman killed in a traffic crash might have suffered a medical ailment which caused the wreck.
Dead is Teresa Michaud.
Lincoln Police Department Officer Katie Flood says investigators believe Michaud suffered a medical episode prior to the deadly wreck.
According to Flood, Michaud was driving east near an intersection in Lincoln when her car suddenly crossed a median, hit a sports utility vehicle, and then rammed into another car.
Three others suffered injuries in the wreck, none life-threatening.
