Authorities searching for a missing Maine girl have seized a sport-utility vehicle belonging to the child's father.

The Portland Press Herald reported Tuesday that police removed two vehicles from the Waterville home where 20-month-old Ayla Reynolds lives with her father, Justin DiPietro.

The child, wearing a soft cast on a broken arm, was last seen by her father in her bed at around 8 p.m. Friday. DiPietro, 24, reported her missing at 8:51 a.m. Saturday when he found an empty bed, authorities said.

No arrests have been made in the case and investigators said it's possible the girl was abducted.

Waterville Police Chief Joseph Massey said during a press conference Monday that several adults visited DiPietro's home Friday night, including at least one non-family member, according to the newspaper.

Searchers have since scoured the surrounding area, including a stream not far from DiPietro's home.

The Herald reported that police removed a 1996 Ford Explorer with a U.S. Marine Corps sticker on the rear windshield from DiPietro's driveway. The SUV is registered to DiPietro, according to records from the Maine Bureau of Motor Vehicles. Also taken was a 2002 Hyundai registered to a Portland woman whose name has not been released, according to the newspaper.

Ayla's mother, Trista Reynolds, told ABC's "Good Morning America" on Monday that she filed paperwork seeking sole custody of the child a day before she disappeared.

Reynolds, who lives in Portland, told the network that she and DiPietro have been unable to get along in the last few weeks. She said she didn't tell him that she'd filed the court paperwork Thursday.

"I've had no contact with him; he's had no contact with me. All I know is he's the last man to see my daughter, and all I want to know is where she is," she said.

Ayla is described as 2 feet 9 inches tall, weighing 30 pounds. She has blonde hair. She was last seen wearing green one-piece pajamas with polka dots and the words "Daddy's Princess" on them.

Massey said investigators have interviewed DiPietro and Reynolds, as well as other family members. He said they all were cooperative.

Police are urging anyone with information on Ayla's whereabouts to call them at 207-680-4700.
