New details have emerged in the case of missing Ayla Reynolds who disappeared from her father's home in Waterville, Maine late Friday. Police and FBI agents are investigating the case, but have found no major leads.

The 20-month old was last seen at 8 p.m. when her father put her to sleep in green, polka-dot pajamas. The next morning Ayla was nowhere to be found and her father reported her missing at approximately 8:50 a.m. The toddler has not been seen since Friday night.

All I know is that he was the last one to see my daughter and all I want to know is where she is, Ayla's mother, Trista Reynolds, told ABC News about DiPietro.

While both Ayla's parents, Justin DiPietro and Trista Reynolds, have been reportedly cooperating with police, it seems Reynolds may have been hiding her plans on Ayla's custody from DiPietro.

We've been unable to get along the last few weeks and parent together, Trista Reynolds said in an interview with Good Morning America.

Reynolds claims she and DiPietro have shared custody of their child, but Reynolds filed paperwork to have sole custody of her daughter the day before Ayla disappeared. She said that DiPietro was not aware of the paperwork.

He didn't know I went to file them. He'll know now, but I never told him and no one told him, said Reynolds on Good Morning America.

Police Chief Joseph Massey claims authorities are investigating all possibilities, including abduction. Everything is open. Everything is on the table, he said according to CBS News.

We need more than just us. We need the help of the general public, Massey said. I suspect that somebody out there may know where the little girl is. ... We'd like to get her back home.

Alya is just under three feet tall and weighs approximately 30 lbs. She has blue eyes and blonde hair. She was last seen wearing pajamas with Daddy's Little Princess written on her top. Her left arm was in a soft cast from an accident three weeks ago.
