At 3:30 p.m. Sunday, the woman called 911 after hearing loud popping noises and seeing bullets ricochet from nearby rocks. At roughly the same time another caller told police he saw someone firing shots from a pickup truck.
That caller followed the pickup to C-470 and stayed on the phone with police. Eventually officers from Parker and Lone Tree pulled the pickup over near Lincoln Avenue and Chambers Road in Douglas County and questioned two brothers inside.
Police found a 9mm handgun inside the pickup along with spent shells. Both of the men told police they didn't know anyone was in the area where they were shooting.
Dinosaur Ridge is a popular hiking spot near I-70 and C-470, and is named after a large number of dinosaur fossils found there over the years.
