SAN ANTONIO, Texas (Reuters) - A Texas woman arrested on suspicion of killing her newborn son and dumping him in the trash told detectives she "strangled the baby and watched him die," according to an arrest affidavit released by San Antonio police on Wednesday. The body of the infant, likely less than a week old, was found stuffed in a duffel bag on the intake conveyor belt of a Waste Management recycling center in San Antonio two days before Christmas.
