A shooting at an Atlantic City outlet mall Thursday left one man dead and a male suspect in custody with a self-inflicted wound, authorities said.

The incident at Tanger Outlets-the Walk, a few blocks from the Boardwalk, involved "a domestic-related matter," the Atlantic County Prosecutor's Office said in a news release.

The victim, identified by authorities as Christopher Romero, 26, of Absecon, N.J., was manager of a Zumiez clothing store, officials said. The alleged shooter, Lewis Maisonet, 55, of Somers Point, N.J., fled across the street, wounding himself at a second store, officials said.

Officials said Maisonet was hospitalized in critical condition.

Rick Brooks, chief executive of the Lynnwood, Wash., company, said Zumiez was "tremendously saddened by the violence" and was working with law enforcement.

Mayor Don Guardian said Romero and Maisonet knew each other, but did not elaborate. No possible motive was released.

The stores were under lockdown while police investigated.

The Atlantic City Press quoted a customer walking out of a Nike store as saying police had come over minutes before and told people to "get out of the way and take cover."

Traffic in the area from the Atlantic City Expressway was temporarily detoured.

The shooting occurred just hours before the Zac Brown Band was scheduled to perform before thousands of people on the beach a few blocks away.

The Walk has more than 100 retail outlets, including Brooks Bros. and Bass Pro Shops.
