A cadaver dog searching for evidence of missing 11-month-old Lisa Irwin "indicated a positive 'hit' for the scent of a deceased human" next to her mother's bed, according to a police affidavit released today.
The affidavit was filed with a Kansas City court to request a search warrant of the family home. That search was carried out Wednesday and police left with several items.
The court document also indicated that Lisa's parents, Deborah Bradley and Jeremy Irwin, restricted police access to the home.
"The only areas extensively processed for DNA and fingerprints during the consent were the baby's bedroom and possible points of entry," the document states.
"The extent of the search had been limited in nature with consent" of the parents, police stated in the request for the search warrant.
The cadaver dog that searched the home on Oct. 17 with the parents' agreement "indicated a positive 'hit' for the scent of a deceased human in an area of the floor of Bradley's bedroom near the bed," the affidavit stated. The consistency and accuracy of cadaver dogs has been challenged in past cases.
The police request for the warrant said, "A more extensive and intrusive search needs to be completed at the property where the baby was last accounted."
New Clues in Disappearance of Missing Baby Lisa?
The document also contained a puzzling comment by Lisa's mother. "Bradley made the statement she did not initially look for her baby behind the house because she 'was afraid of what she might find,'" it said.
In addition, the police cited a "garden area with portions of dirt having an appearance of being recently disturbed or overturned."
The affidavit lists items that investigators took from the house, including a multicolored comforter, purple shorts, a Disney character shirt, a glow worm toy, a Cars-themed blanket, rolls of tape and a tape dispenser.
Bradley has previously told investigators that Lisa was wearing purple shorts and a purple t-shirt when she last saw her on the night of Oct. 3, the night Lisa vanished.
The document also revealed that inconsistent stories from the "people involved" may have hampered the early stages of the investigaton.
"Investigative interviews with the people involved revealed conflicting information for clear direction in the investigation," the affidavit said.
Earlier today, three witnesses in two Kansas City locations told "Good Morning America" they were convinced they saw a man carrying a baby matching Lisa's description the night she disappeared from her Missouri bedroom.
Mike Thompson told ABC News that he was on his way home from work around 4 a.m. on Oct. 4 when he saw a man in a t-shirt carrying a baby at an intersection about three miles from the Irwin home.
It was shortly after 4 a.m. that Lisa's parents said they discovered she was missing.
"[At] 4 a.m., 45 degrees, baby don't have a coat or nothing and this guy is walking down the street and I thought it was kind of weird," Thompson said.
He thought the sight was so unusual that he recalled considering offering the man and baby a ride home, but couldn't because he was on his motorcycle. He later reported what he saw to police and told ABC News he is convinced the baby was Lisa.
Thompson described the man as around 5-feet-7, between 140 and 150 pounds and in his late 30s or early 40s.
A few hours earlier, a couple living three houses down from the Irwin family said they saw a similar sight. A woman and her husband said they saw a man in a t-shirt carrying a baby. They thought the situation was so unusual that they reported it to police on the morning of Oct. 4.
"It was shocking because I couldn't imagine anyone outside walking with their baby in the cold like that with no clothes on," the woman told ABC News.
Bradley has said that Lisa was wearing purple shorts and a purple t-shirt when she last saw her, but the neighboring couple said they baby they saw did not appear to be wearing any clothing.
"We seen the little arm, the leg, it didn't look like the baby had on any clothes, just a diaper," she said.
