A mother on a stroll with her baby was entering the security code to her upscale home, playing with the child while she waited for the gate to open. What she didn't notice was a silver sedan, which had followed her home. When the gate starts to open, two men exit their car and approach hers, demanding the diaper bag. It’s the latest in a string of follow-home robberies plaguing California. One couple was followed 50 miles from a club in Hollywood to their house in Upland, California.
