Police located a young girl in Saugerties, NY who had been missing since 2019, authorities say.

Paislee Shultis should have been celebrating her birthday Monday, but instead she was found by police - allegedly being held captive by her abductors in a small, wet space beneath floorboards at a home in Ulster County.

She went missing from upstate New York two years ago when she was 4 years old.

Saugerties police say she was found alive and unhurt at 35 Fawn Road Monday with her non-custodial parents and paternal grandfather.

News 12 saw two men at the home on Tuesday moving a truck and equipment toward the front of the driveway.

Detectives found Paislee on a search warrant after getting several tips that the girl was there.

Police say at first glance there was no sign of her until they noticed something wrong with some floorboards in a makeshift basement stairwell and saw the girl's blanket and feet.

Neighbors say at least one older child lives there but that no kids were ever seen outside.

Police say the girl's mother, Kimberly Cooper, was found hiding with Paislee.

Cooper and the girl's father, Kirk Shultis Jr., as well as paternal grandfather Kirk Shultis Sr., are charged with custodial interference and endangering the welfare of a child.

Sources tell News 12 Kirk Shultis Jr. was arrested in North Carolina for possession of methamphetamines in 2019, months before Paislee went missing.

The child was transported to police headquarters where she was examined by paramedics and released in good health. She has since been turned over to a legal guardian and reunited with her older sister.

Kimberly Cooper, 33, was charged with custodial interference and endangering the welfare of a child. She also had an active warrant issued through the Ulster County Family Court and was remanded to Ulster County Jail.

Kirk Shultis Jr., 32, and Kirk Shultis Sr., 57, were charged with the felony of custodial interference in the first degree and misdemeanor endangering the welfare of a child. They were arraigned and released on their own recognizance.

Stay-away orders were issued for each defendant.
