A mother is behind bars and a father is on the run after an infant was left alone at a truck stop on Sunday evening. Employees at a truck stop along El Centro Road, just north of downtown Sacramento, watched as a man and woman lingered nearby with a baby in a carrier. Then they both left, leaving the child alone. Deputies arrived to find employees entertaining the six-week-old girl, and no sign of the parents. The child was taken to the hospital to be evaluated.
