PONTIAC, Ill. -- Police in Pontiac, Ill. held a news conference Friday to discuss the case of a former Florida couple who believe a girl in Pontiac may be their missing daughter.

NBC5's Charlie Wojciechowski reported that officials have taken DNA samples from the little girl to see if they match the missing infant's DNA. The sample will be sent to the FBI's testing facility. Results of those tests are not expected for two to three weeks.

Sabrina Aisenberg was abducted five years ago from her suburban Tampa home, at the age of 5 months. Initially, her parents, Steven and Marlene (pictured, left), were indicted for her murder, but the charges were later dismissed and the couple won a $3 million judgment against the federal government.

After Sabrina's disappearance, Hillsborough County sheriff's investigators suspected the Aisenbergs and got a judge's permission to put listening devices in the couple's kitchen and bathroom. Two years later, a grand jury indicted the couple on federal charges of conspiracy and making false statements.

But a federal judge found the tapes mostly inaudible, and they were thrown out as evidence when it was determined that detectives lied to get permission to bug the home. The federal government was ordered in January to pay $2.8 million in legal fees to the Aisenbergs, who now live in Bethesda, Md.

Last March, the Aisenbergs were alerted to a picture of a 6-year-old girl on a missing children Web site. The Aisenbergs believe the child, named Paloma (pictured, right), resembled Sabrina, and they request that DNA tests be performed to see if Paloma is their daughter.

"We're very optimistic about any lead that we get and this one especially because there's a picture, there's a location of where this girl is," Steven Aisenberg said. "There's something that can be done, like a DNA test."

Missing Child Found?

Pontiac police told the Aisenbergs' lawyers that the child came to a family there through a woman in McAllen, Texas, who was being deported. A nurse then took the child and gave her to a sister in Pontiac, the attorney for the Aisenbergs said.

The child was passed around with no birth certificate or other legal identification, "which is something you'd expect with a child that was kidnapped," the attorney said, adding that he did not know girl's or the family's last name.

The Illinois family has raised the child since about late 1998, but a judge would not allow her adoption because she didn't have a birth certificate. The judge ordered a search for the child's parents, and her picture was posted on a missing children's Web site.
