Messages and handprints are left on a rock just below a giant Q in honor of Quinton Robbins on Saturday, Oct. 21, 2017, on the mountain east of Basic High School in Henderson. Friends and family of Robbins, who was killed in the Route 91 Harvest festival shooting, started working on it at 8:30 a.m. and finished at 2 p.m. Greg Haas Las Vegas Review-Journal @RJgreg09
