CAMDEN - A Camden man was sentenced to more than four years in prison on Thursday for taking part in the robbery of an Atlantic City mail carrier in 2007, U.S. Attorney Paul J. Fishman said in a release.

Ismael Gonzalez, 21, was sentenced to 50 months in federal prison by U.S. District Judge Robert B. Kugler. He must also serve five years of supervised release after leaving prison.

Gonzalez, who was also known as "Emilio Gonzalez" and "Darwin Ordonez," pleaded guilty on June 2, 2009 in front of Kugler, Fishman said.

Gonzalez said on June 15, 2007 he and Doni Maldonado waited in the lobby of Building C of the Chelsea Village Apartments for a U.S. Postal Service mail carrier.

With Gonzalez acting as a lookout, Fishman said Maldonado hit the mail carrier on the side of the head as the carrier tried to open the apartment's mailboxes with his access key.

The attack caused the mail carrier to fall down and suffer a skull fracture, Fishman said. Maldonado took the key and fled. Gonzalez admitted he and Maldonado subsequently used the key to steal mail from at least one other building's mailboxes.

Maldonado, a 26-year-old illegal immigrant from Honduras living in Atlantic City, pleaded guilty before Kugler on Sept. 19, 2008.

He was sentenced to 57 months in prison on April 3, 2009 and was ordered to cooperate with Immigration and Customs Enforcement about his immigration status, a spokesman for the US Attorney said at the time of sentencing.
