It has been three years since a gunman opened fire at a Las Vegas music festival, killing 58 and wounding more than 400 others. On the third anniversary, school children at St. Viator Parish School in Las Vegas turned to prayer as they remembered the day. Students reflected on Psalm 148, or “Praise to the Lord from Creation,” before reciting the Prayer of St. Francis. They ended by saying a decade of the rosary, something they have done every year, since the morning after the tragedy.
