Woman in wheelchair tumbles down escalator at Portland airport

Video at Portland International Airport shows Bernice Kekona mistakenly steering her motorized scooter toward an escalator, then falling down it on June 7, 2017. She died from an infection more than three months later, and her family filed a lawsuit against Alaska Airlines and a subcontractor this week -- claiming Kekona was supposed to be escorted through the airport.
