A Hispanic couple have been charged in the starvation death of their 3-year-old daughter, who weighed only 11 pounds

Carlos Rivera, 30, and Carmen Ramirez, 27, brought their unresponsive daughter, Nathlayz Rivera, to Einstein Medical Center in Philadelphia, where the child was pronounced dead, according to Officer Jillian Russell. Rivera and Ramirez have been arraigned on charges of third-degree murder, involuntary manslaughter, and conspiracy and endangering the welfare of a child, according to Philadelphia District Attorney's Office spokeswoman Tasha Jamerson. Both parents are being held without bail, and their next court date is scheduled for September 25, 2013 Jamerson said. Four other children - ages 9, 8, 7 and Nathlayz's 3-year-old twin - lived at the couple's residence. The children were taken to a local hospital where they were examined and then transported to the Philadelphia Department of Human Services, Russell said. The mother told detectives that Nathlayz had Down syndrome, police said.
