Five-Month-Old Baby On Life Support Dies

CHICAGO (CBS) -- A five-month old girl, who had been on life support since last Friday, has now died.

Police say Angelina Rodriquez' parents had been charged with aggravated battery after the father allegedly covered the girl's mouth repeatedly to muffle her cries.

At this time, authorities say they're not sure whether charges against the parents are being upgraded due to the baby's death.

Doctors also noticed older skull fractures while examining the daughter of Rodrigo Rodriguez, 29, and Angela Petrov, 21, of Chicago's West Rogers Park neighborhood, Cook County Assistant State's Attorney Stephanie Buck said during a hearing in bond court on Sunday.

Buck told Cook County Judge James Brown the couple was drinking Hennessy in the room where their daughter was sleeping in her playpen and the girl began to cry. The judge crossed his arms and shook his head as Buck explained what happened next, and he ordered both parents — each charged with aggravated battery of a child — held in lieu of $5 million bail during separate hearings.

But Rodriguez's mother, Crucita Rivera, said after her son's bond hearing the allegations against him aren't true. She said he suffers from bi-polar disorder.

"He would never do that," Rivera said.

But prosecutors offered a different story in court, saying the couple is responsible for the injuries so severe it left the infant with little brain activity.

Prosecutors say Rodriguez smothered the baby's mouth with his hand three times last Thursday night until the baby went limp.

At 11 a.m., the next day, the parents found their child unresponsive.
