NEWTOWN, Ct. -

Federal authorities arrested a woman Thursday after they say she scammed donors who thought they were giving money to the family of a Newtown, Connecticut shooting victim.

Police say 37-year-old Nouel Alba used a Facebook account to pose as the aunt of 6-year-old Noah Pozner. Investigators say she solicited money claiming it would be used for a funeral fund.

Donors then transmitted money ot a PayPal account set up by Alba.

Pozner's uncle reacted with disgust to the scam.

"I look at my nieces and I think of these scammers, and they're stealing from them," Alexis Haller said. "They're survivors of this tragedy."

Alba, who is a mother of two teenagers, even sent elaborate messages to donors.

U.S. Attorney David Fein says the arrest should serve as a warning to anyone looking to profit from the tragedy.
