Hearts are breaking at the Lincoln Park Zoo where a baby gorilla, just 9 days old, has been found dead in her mother's arms.

RadarOnline.com brought you the first video of the baby girl Western lowland gorilla on Tuesday.

She was born to a 15-year-old first-time gorilla mom named Bana. Dad was a 22-year-old silverback named Kwan.

Zoo officials discovered that the baby was dead after seeing Bana carrying her lifeless body Friday. They allowed the grieving mom to continue caressing the infant for several hours.

An autopsy found that the baby had died from head trauma, but no one saw what had happened to cause the injury.

The Zoo has since been flooded my messages of sympathy.

A little new arrival is a big hit at a Chicago zoo as a baby gorilla greeted the world for the first time on Tuesday, and RadarOnline.com has the adorable video of the miniature King Kong.

The as-yet unnamed girl is the first western lowland gorilla to be born at the windy city's Lincoln Park Zoo since 2005 and crowds rushed to her new home to see the bald baby ape, who was born last Thursday.

The new parents are first-time mom Bana, 15, and her mate, 22-year-old silverback Kwan, who "seems proud of his new offspring and has stayed protectively close to mother and baby," said a zoo official at the Regenstein Center for African Apes, according to a report from NBCChicago.com.
