A Phoenix flight attendant was among four people stabbed during a two-day rampage in Denver over the weekend. Two people were killed, including a flight attendant, 71-year-old Celinda Levno, who was on a layover.

A Phoenix-based flight attendant was the victim of a deadly stabbing on Denver's 16th Street Mall, according to her representative.

Celinda Levno, 71, died between Saturday night and Sunday morning from a "senseless tragedy," said the Association of Professional Flight Attendants.
