Amber Alert issued for Colorado girl, 10

Westminster Police via AP By Miguel Llanos, NBC News Dozens of police, firefighters and volunteers were searching a neighborhood in Westminster, Colo., on Saturday after a 10-year-old girl vanished Friday morning on her way to school. Jessica Ridgeway was last seen by her mother as she took her normal three-block walk to a park to meet a friend on their way to school.  The friend told school officials that Jessica never showed up, NBC station KUSA-TV reported. They tried calling the Jessica's mother, but she reportedly slept through calls after working a night shift. An Amber Alert was issued Friday evening once the mother confirmed that her daughter was missing. Teams searched overnight and continued Saturday, using search dogs as well as going door-to-door around the neighborhood in Westminster, a suburb of Denver. Officials contacted the child's father, who lives in another state, the Denver Post reported. "At this time we don't have any indication he is involved in any way," Westminster police spokeswoman Cheri Spottke said.
