The baby Amanda Berry gave birth to while she was held captive in a Cleveland home was delivered by another one of the young women in the house, according to a police source familiar with the investigation.
The information was corroborated in a police report seen by CNN. When Berry went into labor, Ariel Castro, now charged with kidnapping and rape, grabbed captive Michelle Knight and told her to deliver the baby.
The baby was born into a plastic tub or pool to contain the afterbirth and amniotic fluid.
When the baby was born, it stopped breathing and everyone started screaming, the source said, citing the girl's account. Castro allegedly said, "if that baby dies, I'm going to kill you."
"What's most incredible here is that this girl who knows nothing about childbirth was able to deliver a baby that is now a healthy 6-year-old," the source said.
The three women spent their days and nights captive at 2207 Seymour Avenue, a 1,400-square-foot home in one of Cleveland's oldest neighborhoods. They went outside only twice in that span -- just "briefly" at that -- Cleveland public safety director Martin Flask said.
More often, the three would be in different rooms, though they interacted occasionally and came to "rely on each other for survival," said a law enforcement source with direct knowledge of the investigation.
One thing they could count on was that their alleged captor would never let them out.
Castro would often test Berry, Knight and Georgina "Gina" DeJesus, the young women he'd allegedly abducted, by pretending to leave, said the law enforcement source. He'd return suddenly: If there were indications any of the women had moved, they'd be disciplined.
Years went by. In that time, the women saw their parents on television at vigils held for them, according to the law enforcement source. They got emotional, knowing their loved ones were looking for them.
And in time, Knight and DeJesus "succumbed" to "their reality," the law enforcement source said.
But "something must have clicked" for Berry on Monday evening, said Cleveland's deputy police chief Ed Tomba. She staged a daring escape, and with the help of Castro's neighbors Charles Ramsey and Angel Cordero, freed herself, her 6-year-old daughter, Knight and DeJesus.
On Wednesday night, Castro, the man who allegedly held them against their will for so many years, was behind bars.
He'll be arraigned Thursday morning on four counts of kidnapping and three counts of rape tied to the case, said Victor Perez, chief assistant prosecutor for the city of Cleveland.
The women found in his home, meanwhile, are back with family -- the same relatives who cried and struggled but, for the most part, never gave up hope.
"I knew my daughter was out there alive," said Felix DeJesus, Gina's father, moments after she arrived Wednesday afternoon at a family home in Cleveland. "I knew she needed me, and I never gave up."
Lured into a vehicle, then trapped in a home
Knight was 21 on August 22, 2002, when Castro lured her into his vehicle along Cleveland's Lorain Avenue, according to charging documents. Castro took her back to his home on Seymour Avenue, about three miles away, and didn't let her go.
In that time, Knight was sexually assaulted repeatedly, the documents state. But soon, she wasn't alone.
The next year -- on April 21, 2003, the eve of her 17th birthday -- Berry experienced the same nightmare scenario. While walking home from her job at Burger King that night, she too took a ride from Castro on Lorain Avenue.
Almost exactly a year later, they were joined by DeJesus, then all of 14 years old.
They remained in that hell until Monday evening, when Berry screamed for help. Hearing her cries, Ramsey and Cordero kicked in a door to help her escape.
According to Cordero, Berry's 6-year-old daughter ran out of the house too, wearing only a diaper and a sullied shirt. Police are conducting a DNA test to determine the child's paternity.
"Help me, I am Amanda Berry," Berry begged a 911 operator from Ramsey's house. "I've been kidnapped, and I've been missing for 10 years. And I'm here, I'm free now."
Cleveland police Chief Michael McGrath told NBC's "Today" show that the women were bound and that there were "chains and ropes in the home."
