WATERVILLE, Maine (AP) — The three-month anniversary of the disappearance of a toddler in Maine is passing quietly, but police say the investigation is continuing.

Ayla Reynolds was 20 months old when she was last seen on the night of Dec. 16.

She was reported missing the following morning when her father said he discovered her bed empty.

Police are treating her disappearance as a crime, but no one has been charged.

Steve McCausland of the Maine Department of Public Safety says investigators have received more than 970 leads, and detectives continue to conduct interviews.

He says the crime lab is providing new evidence almost daily.

Ayla was living with her father, Justin DiPietro, in Waterville when she disappeared.

Her mother, Trista Reynolds, lives in Portland.
