News 12 has learned that 6-year-old Paislee Shultis, who went missing for two years and found alive after being stowed under a stairwell in Saugerties, had two siblings who died as infants before she was born.

Haylee Shultis died May 2, 2010 at Kingston Hospital and Kaylee Shultis died when she was 5 days old on July 22, 2011 at Vassar Brothers Hospital in Poughkeepsie, according to online records.

News 12 does not know why the infants died, and death records are not public information.

It is also not known if their deaths had anything to do with the family's custody case.

Haylee Shultis and Kaylee Shultis were born after Paislee's older sister.

Paislee was found hidden in a locked box Monday beneath a stairwell at the parents' home in Saugerties, two years after her maternal grandmother was awarded custody and the parents allegedly took her.

A former family babysitter says there were safety concerns after the father's arrests for construction fraud and methamphetamine, which News 12 confirmed with prosecutors.

Paislee's parents and grandfather are facing criminal charges in her abduction.

Paislee and her sister are now safe with their grandmother who has legal custody of them.
