Nouel Alba is accused of scamming people by claiming to be the aunt of a little boy killed in the shooting in Newtown.
A woman charged with trying to swindle donors by posing as a relative of a child killed in the Connecticut school massacre had also been soliciting money for Sandy relief.
Nouel Alba was arrested Thursday and accused of concocting bogus tales about having to identify her nephew's body in order to raise money for a "funeral fund'' for the victims.
The New York Post reports that in the days after Sandy struck, Alba had also been posting Web messages claiming she had founded several charities to assist storm victims.
But the postings were filled with false claims, as well as an invalid tax-ID number for one organization.
In an interview with CNN before her arrest, Alba denied being involved in any scam.
