No Sign of Missing Pennsylvania Mother, Daughter Allegedly Abducted After Car Accident

A massive manhunt for a missing Pennsylvania mother and daughter who allegedly were kidnapped after a minor car accident turned up no sign of the pair Wednesday, as the mystery into what happened to them deepened.

Police are planning to examine the silver SUV belonging to Bonnie Sweeten, 38, that was found in Center City, Philadelphia, before dawn.

Sweeten reportedly called 911 Tuesday and said she was locked in the trunk of a car after she and her 9-year-old daughter Julia Rakoczy were kidnapped in broad daylight.

"Based on what she says, they supposedly took her car and she was put in another car, but right now that's all we have to go on," said Philadelphia Police Lt. Frank Vanore, who heard the tapes. "It definitely sounds like she's afraid. ... But it's hard to tell what's going on."

Detectives and reporters have been puzzled by holes in Sweeten's story, and FBI spokesman J.J. Klaver confirmed the existence of "inconsistencies" in her account of the accident and abduction. But he declined to elaborate and said those aren't the focus of the investigation.

In at least two cell phone calls she said she was making from a locked car trunk, Sweeten told emergency dispatchers that she and her daughter were snatched in the middle of the day Tuesday by two black men who rear-ended their SUV in suburban Philadelphia, according to police."We're not concerned about any inconsistencies," he told FOX News. "Our main concern is finding that young girl and her mother."

Though Sweeten, of Feasterville, Pa., implied her daughter was with her, the girl is not heard on the tapes, Vanore said.

Authorities haven't found either Sweeten or Julia after the early-morning discovery of their vehicle in Philadelphia Wednesday.
