Witnesses watched in horror as Harpham picked his victims off. One of them, the bicyclist, pleaded for his life before being killed.From here.
"I heard the (young man) say, 'Don't shoot me! Don't shoot me!' " Naomi Bettis, a neighbor who witnessed the killing, said Monday.
Bettis said she recognized the gunman as her neighbor — whom she didn't know by name — and that before the initial slaying she saw him roaming outside with a rifle. She called 911 to report the man, but a dispatcher explained that Colorado has an open carry law that allows public handling of firearms.
"He did have a distraught look on his face," Bettis said. "It looked like he had a rough couple days or so."
After Harpham shot the bicyclist, Bettis said she watched him walk toward Platte Avenue. She then heard more gunfire.
