No DNA match for missing Florida girl
Police say sisters have failed lie detector tests
MIAMI, Florida (CNN) -- Two Florida sisters who were taking care of a 5-year-old girl who vanished more than a year ago have failed a portion of polygraph tests they took, the director of the Miami-Dade police told CNN Friday.
Meanwhile, results of a Kansas City police DNA test have shown no match between Rilya Wilson and an unidentified little girl called "Precious Doe," found dead in Kansas City, Missouri, in April 2001.
Kansas City police canceled a scheduled Friday news conference and made the announcement on their Web site after CNN reported the results, obtained from sources close to the case in Miami. (Read the full report on the Kansas City Police Department's site.)
Rilya Wilson is still listed as a missing person, but police said they're treating the case as a homicide investigation. Despite the sisters' failed lie detector tests, Miami-Dade Police Director Carlos Alvarez stressed that police weren't prepared to name a suspect.
He said that Pamela and Geralyn Graham had voluntarily submitted to the lie detector tests. Police sources said they were releasing the polygraph results to "shake things up."
Rilya Wilson was in the legal custody of Pamela Graham in January 2001, but it was her sister Geralyn who told authorities last month that a "professional-looking woman" who said she was from Florida child welfare had taken the little girl in January 2001.
Graham said that the woman returned a few days later, saying the tests were taking longer than expected -- and neither the woman nor Rilya were heard from again.
The disappearance was discovered last month when a Florida Department of Children and Family Services caseworker contacted the Grahams for a meeting about the girl. It was the first of what should have been ongoing monthly meetings.
But Alvarez told CNN that "both failed polygraphs."
"They showed signs of deception," he said. "At this point, we don't know who's telling the truth and who's not."
Rilya Wilson was placed in the custody of Pamela Graham in 1999 after the paternal rights of the girl's parents were terminated. Geralyn Graham calls herself Rilya's paternal grandmother, though no blood test has been made to confirm the identify of Rilya's father.
Florida Gov. Jeb Bush set up a blue-ribbon panel to investigate the case, and the panel was to hold its second meeting on Friday.
'Can't hide her forever'
Geralyn Graham told CNN that she never believed that Precious Doe in Kansas City was Rilya Wilson, and that she believes Rilya is still alive and lost in the Florida child welfare system.
"Whoever has her, and I know somebody does, they need to remember one thing: You can't hide her forever," Graham told CNN.
Graham and her sister told CNN this week that they took the lie detector tests voluntarily because they have nothing to hide.
Gerayln Graham's attorney told CNN that his client was under heavy medication, which likely rendered the polygraph unreliable.
Polygraphs are used by police as investigative tools, and test results aren't admissible in court. Their reliability is questioned by many scientists.
