SAN DIEGO -- Police arrested a San Diego woman after she allegedly put her 2-year-old son in front of a freight train and, later, in front of a Trolley Tuesday evening. Investigators said Rachel Garta, 22, pushed the boy onto tracks near Front Street and Harbor Drive, NBC 7/39 reported. Witnesses said the boy stood on the tracks as a freight train approached at about 7:30 p.m. The conductor saw the boy and hit the emergency brakes, stopping the train before it hit the child. At that point, witnesses said, a Trolley security guard yelled at the woman and boy to get off the tracks. Police said the woman then pushed the boy onto the other tracks, where a Trolley was approaching, NBC 7/39 reported. The Trolley operator also stopped in time, and a Trolley security officer pulled the boy off the tracks. http://www.nbc4.tv/news/5180041/detail.html I am sick over this.
