An Amber Alert is in effect for two children missing out of Colorado, who investigators believe could be headed to Idaho. Police believe the children, ages seven and 11, were taken from a bus stop by their biological mother, Tammy Rees-Romero, and her boyfriend, Jacob Lake-Sahm. They are believed to be traveling in a 1997 maroon Mercury Grand Marquis four door sedan with Colorado tags with a license plate that reads: 617-SZM.
