NEW YORK -- The widow of a Port Authority police officer killed on 9/11 was victimized again when her broker stole $250,000 from the compensation payment she received, federal prosecutors said.

Former MetLife broker Kevin Dunn, 28, was arrested Thursday morning by U.S. postal inspectors on mail and wire fraud charges.

Sources told wnbc.com the victim of the alleged fraud is Jamie Amoroso. Her husband, Port Authority Police Officer Christopher Amoroso, was 29 when he died.

"It's sad that a person has to be victimized because they lost someone in the Trade Center attacks," said U.S. Postal Inspector Maria Albright. "And then someone like the defendant comes along and victimizes them all over again."

Investigators said Dunn used some of the cash for mortgage payments on his Colonia, N.J. home and vacations in Florida. "The forfeiture allegations do refer to a time share in Disney," Albright said.

Dunn pleaded not guilty during his arraignment. Outside court, Dunn's lawyer Mario Gallucci, said his client is a "good guy, hard working, married, two children and is friends with the victim."

In addition to his wife, Officer Amoroso had a daughter who was just 19 months old on Sept. 11.

Jamie Amoroso received $2 million after her husband died trying to save others when the towers fell.

Investigators said Dunn kept telling the widow that there was a problem with her account and that she needed to send him a blank check so he could fill in the correct information and fix the problem. Instead, they said, he made off with the cash. They said Dunn forged his client's signature on several documents in order to wire the funds to his personal accounts.

"We will vigorously investigate and prosecute those who would exploit the tragedy of the September 11 terrorist attacks for their own gain," said U.S. attorney Roslynn Mauskopf.

A spokesman for MetLife said when the company learned of Dunn's alleged wrongdoing, they were the ones who alerted police. "This is a matter that Met Life uncovered and subsequently referred to the proper authorities," said MetLife's Chris Breslin. Breslin added Dunn no longer works for the company.

If convicted on the counts, Dunn could face up to 20 years in prison.

A spokeswoman for the Securities and Exchange Commission said that in addition to being responsible for the $250,000 allegedly stolen, Dunn could face up to $500,000 in fines.

"Postal Inspectors will apply all available resources to investigate and arrest those who target the families of the victims of 9-11," said NY Postal Inspector-In-Charge Ron Walker.

Of the nearly 3,000 people killed on Sept. 11, 37 of them were Port Authority police officers.
