The city of Boulder encouraged people nationwide to hold a moment of silence and conduct a candle-lighting ceremony to honor the victims of a mass shooting at a local supermarket that killed 10 people last week.
Boulder officials asked participants to observe 10 minutes of silence and leave a candle or light in front of their homes at 8 p.m. Saturday to honor the victims. The ceremonies had to be conducted privately in lieu of a mass gathering because of health restrictions related to the coronavirus pandemic.
