Berry's sister, Beth Serrano, spoke to reporters briefly, asking for privacy "until we are ready to make a statement." She added, "We are elated, this is a happy ending."

The three brothers accused of the kidnappings are likely to face charges Wednesday. Prosecutors will decide whether to charge all three brothers--Ariel Castro, Pedro Castro and Onil Castro.

Police said they found chains and ropes at the premises where Berry, Gina DeJusus and Michelle Knight were held, but no human remains.

"We have confirmation that they were bound, and there (were) chains and ropes in the home," said Cleveland Police Chief Michael McGrath in an appearance on NBC's "Today" show.

McGrath said police believe the three women were kept hidden inside and only occasionally allowed into the backyard.

The police chief disputed neighbors' claims that there were at least two phone calls in the past few years for reports of suspicious activity, saying there is no record of those calls. Neighbors said a naked woman was seen crawling on her hands and knees in the back yard a few years ago and, in 2011, pounding was heard on the doors. They said police showed up but did not enter the house either time.

The three women were rescued after Amanda Berry, who was kidnapped at age 17, stood at the front door of the house with a young child, screaming for help. Two neighbors helped break down the door and called 911.

Berry is expected to release a statement later Wednesday.
