LAKEWOOD, Wash. -- Recent lie detector tests, performed by Lakewood Police on the parents of Adre'Anna Jackson are all part of and ongoing investigation. It's been 19 days since the 10 year old girl disappeared. The young girl's mother says she's glad authorities made them take the tests, because they have nothing to hide. "No we did not have anything to do with the disappearance of our daughter." said Yvette Gervaise.

Her mother is now sharing new video of the smiling 10 year old taken at a friends home this summer. Adre'Anna vanished after heading to school on a snow day when classes were cancelled.

On Tuesday, the girl's mother and her stepfather Jon Federicci were given lie detector tests to eliminate them as suspects in the disappearance. Authorities say her mother passed and Federicci's tests came back inconclusive. "My hope, somebody is holding her and she is still alive and please don't make her suffer," Gervaise said.

Investigators are also looking for hair and fiber evidence on a dumpster near a boat launch at American Lake. It's the same place a boat was recovered earlier this month

And in another part of this investigation..detectives confiscated Adre'Anna's underwear, and her fathers underwear. Both are being tested for DNA.

A $1000 reward is being offered in this case by Crimestoppers.
