A FBI cadaver dog hunting for missing baby Lisa Irwin detected the scent of a dead body on the floor of her parent's bedroom, according to court documents filed on Friday, RadarOnline.com has learned.

The trained sniffer dog reported a "hit" on Monday inside the Kansas City, Missouri home where the 11-month-old baby was last seen in her crib on the evening of October 3, reported the Wichita Eagle.

The new development in the case that has captured the attention of the country was detailed in an affidavit that the police filed to support a request for a search warrant of the house, which resulted in an extensive search by police and federal investigators on Wednesday.

It has been over two months since Robyn Gardner vanished without a trace in Aruba and now the authorities on the island have amped up the search by bringing in sniffer dogs.

Robyn's longtime boyfriend, Richard Forester, has said from the early days in the investigation that he wished they would bring in Dutch dogs to help with the search.

"I am glad that they brought dogs in and I'm happy about it, I just wish that they had done it sooner," he told RadarOnline.com in an exclusive interview.
