Six weeks after Ayla Reynolds went missing, police revealed Saturday that blood has been found in the Waterville, Maine home where the toddler was last seen.

The news that Maine State Police investigators are analyzing blood they found in the home where Ayla Reynolds went missing the morning of Dec. 17 broke while a vigil was hosted in the girl's honor downtown Waterville, the Associated Press reported Saturday.

State police spokesman Steve McCausland told the AP that investigators had found blood early on in the investigation into the disappearance of Ayla Reynolds from the home of her father, Justin DiPietro, who reported the 20-month-old missing that fateful winter day.

The news that blood had been discovered in DiPietro's home was first reported Saturday by WCVB-TV in Boston

McCausland called the existence of the blood--which has been undergoing testing in a state crime laboratory for testing ever since it was found--troubling, the AP said. No results of the tests have been released yet, and authorities did not indicate when such results may be forthcoming.

We have questioned the three adults that were there in the home that night, McCausland said. We believe they have not given us the full story.

Ayla Reynolds was staying with DiPietro when she was reported missing, and her mother, Trista Reynolds, lives in Portland, Maine, according to the AP. 

DiPietro told police early on in the investigation that he believed his daughter may have been kidnapped from her bedroom in his home, located at 29 Violette Ave., Waterville, Maine, according to WCVB-TV.

DiPietro said I would never do anything to hurt my child earlier in the investigation, and he has said that he has passed a polygraph lie detector test administered by investigators, WCVB-TV reported.
