Two windows were smashed at the home of missing toddler Ayla Reynolds, police said today.

Officers responded to a 911 call at the Waterville, Maine home around 11:15 p.m. last night after Reynolds' grandmother, Phoebe DiPietro, said she heard someone throwing things through windows at the house.

"No rocks or thrown objects were recovered, leading officers to believe that the windows were damaged by a bat or some other object that was carried away from the scene," Waterville Police said in a statement.

Police conducted a search of the surrounding area, but it did not turn up any leads.

The twenty-month-old has been missing from her home since Dec. 17.

Reynolds' father, Justin DiPietro, 24, told police he last saw his daughter when he put her to bed that night.

Police have classified the disappearance as a crime and have found traces of Ayla's blood in a basement her father had been using as a bedroom.

"What [police] were unwilling to confirm to the press, but left to our discretion, is that it has already been determined to be Ayla's blood," the statement said. "Even in light of this evidence we are more determined than ever to find out what has happened to Ayla and we still cling to the hope that she is alive and will be returned to us. We urge anyone that has information about Ayla to come forward now and unburden yourself of the truth."

Officials searched parts of the Kennebec River Friday, but did not find anything new.
