The Daily Camera reportsthe group will walk on downtown's Pearl Street Mall at noon Sunday. Participants are expected to be silent during the walk but plan to play a recording of an elk bugle from their phones.
Police say an on-duty officer killed the animal Jan. 1, and an off-duty officer took the elk home to be processed for meat. The officer who shot the elk allegedly said it was limping and appeared as if it needed to be put down, though a resident has said it wasn't limping a few hours before it died.
Colorado wildlife officials are investigating whether any crimes occurred.
