(Cleveland) - Police Chief Michael McGrath has confirmed that chains and ropes were used to bind the captives on Seymour Avenue.

In an interview with NBC's "Today Show". McGrath says those were among the items removed from Ariel Castro's home.

On Monday, Amanda Berry, Gina DeJesus and Michelle Knight all escaped from the home where they'd been held prisoner.

McGrath could not answer every question about the investigation, but did say that reports of multiple pregnancies among the women could not be verified at this time.

Cleveland Safety Director Marty Flask confirms no human remains were found in the home or yard.

Chief McGrath also says the charging process against Ariel, Pedro and Onil Castro is underway, but he would not say what charges each could face. He did say the three are being interviewed and are talking.

When asked if police had done all they could to find the missing girls, McGrath said, "Absolutely". He says task forces had been formed and any and all leads have been investigated.

McGrath also says there are no records that calls were made to Cleveland Police about odd occurances at the house, despite some comments by neighbors.

The investigative teams will meet Wednesday afternoon to discuss what was found in the house.
