This morning, both attorney Ralph Hagans and Rivera's mother told the judge the baby had a history of falling, especially on his head
"My girlfriend's baby is not breathing!" Rivera shouted on the 911 recording, released by police.
As Rivera forwarded cardiopulmonary resuscitation instructions from the 911 operator, his mother could be heard sobbing.
"'I'm pressing down," Delao said. "Please. Help!"
Then Rivera was heard saying, "The paramedics are here. C'mon. Hurry! Hurry! Hurry! In the back room! In the back room! Here! Here!"
The police report said an officer found Rivera's mother, with the child across her lap, attempting CPR.
It said the weeping woman handed the limp child to the officer, who found no evidence of breathing or a pulse.
Fire Rescue workers who took the baby to Boca Raton Community Hospital saw bruising on his face and body.
Christiano later was transferred to Delray Medical Center in critical condition; he died the next evening.
The doctor who performed the autopsy "advised that the injuries could not have been sustained by the child thrusting himself backward in the playpen, as Carlos Rivera claimed, or by falling out
," the report said.
The child's mother, Jessica Belle-Chaves, who had moved in with Rivera and Delao a few weeks earlier, told police that, a few days before the child died, she had left Rivera home alone with Christiano for 15 minutes. When she'd returned, she said she found the child with redness on his forehead and head and a swollen right arm.
She said Rivera had said the baby had fallen, but she also said that room was carpeted, the report said.
The day Christiano was hurt, the child's mother said, Rivera had ordered her out of the home, and when she'd returned, she found the baby lying on the floor.
She said Rivera told her he'd found the baby biting his lip and clenching his hands
and "panicked and kicked the baby in the stomach to see if he was ok,"
the report said.
It said Belle-Chaves told police Rivera then told her "the baby appeared to snap out of it and he put him back in the playpen."
She said she saw the injuries and suggested taking the baby to a hospital.
But she said Rivera told her he feared the Florida Department of Children and Families would take the child.
Rivera later told police the baby had "hit his head really bad" but was OK the rest of that day and the morning.
He said the boy had gone to sleep. When he checked on the baby 30 minutes earlier, he was unresponsive and turning blue.
That's when Rivera called 911, police said.
