Elijah Caudill, 24, has been charged with two counts of first-degree murder in connection with the stabbing deaths of Celinda Levno and Nicholas Burkett.

After two people were killed and two others wounded in downtown Denver, a suspect has been arrested and now faces charges related to the attacks. See a timeline and map of when and where those attacks took place.

The family of 34-year-old Nick Burkett started a memorial of candles, flowers and pictures near 16th Street and Wazee Street in downtown Denver on Friday, just days after his death. He and 71-year-old Celinda Levno were killed in two of the four random stabbings along the 16th Street Mall last weekend.
