(CBS/AP) WATERVILLE, Maine - Police say they've found no evidence missing toddler Ayla Reynolds was abducted and believe they haven't been told the whole story.

State and local detectives believe Justin DiPietro, the girl's father, and two other adults present the night Ayla disappeared know more than they've told investigators so far, said Steve McCausland, spokesman for the Maine Department of Public Safety.

The notion that someone slipped into the small house and took Ayla without awakening anyone "doesn't pass the straight-face test," McCausland said.

"We've followed every conceivable piece of evidence that would follow their version of events, and we have found not one piece of evidence that supports an abduction," he told The Associated Press.

Police confirmed Sunday night that Ayla's blood was found in the partially finished basement that DiPietro used as his bedroom. Relatives reported on a family-run website that they were told the blood was "more than a small cut would produce," but police declined to say how much blood was discovered.

DiPietro reported Ayla missing on Dec. 17, telling police he'd put his 20-month-old daughter to bed the night before and she wasn't there the next morning. DiPietro, his girlfriend Courtney Roberts, and DiPietro's sister were all in the house at the time.

McCausland said detectives weren't singling out any of the three adults, but "we think they know more than they're telling us," he said.
