A police affidavit says a woman told San Antonio police investigators that she wrapped a ligature around her infant son's neck, saw him cry and watched him die.
According to the arrest affidavit, Nidia Yolibeth Alvarado told investigators that she then placed her newborn son's body in a duffel bag and dumped his body at a San Antonio recycling plant.
Alvarado has been charged with capital murder after her Tuesday night arrest. She was in the Bexar (BAYR) County Jail on Wednesday night with bond set at $2 million. A jail booking clerk said no attorney was listed in her jail record.
A medical examiner says the newborn was found Dec. 23 in a duffel bag discovered by a recycling plant worker.
