STATEN ISLAND, N.Y. -- Police seek help identifying a man wanted for questioning in connection with the death of L&B Spumoni Garden co-owner Louis Barbati last week.

Barbati, 61, was found with gunshot wounds to his torso outside his home on 12th Avenue in Brooklyn's Dyker Heights section, just after 7 p.m. on Thursday, police said.

He was pronounced dead at the scene.

The gunman, described in media reports as a white hooded male in his 30s, fled the scene and remains at large Tuesday afternoon.

Police released surveillance video of a man sought for questioning in connection with the slaying, taken before the incident near the crime scene, police said.

Anyone with information about the shooting is asked to call the NYPD's Crime Stoppers hotline at 800-577-TIPS (8477); visit nypdcrimestoppers.com or send text tips to CRIMES (274637), then enter TIP577.

The restaurant was founded by Barbati's grandfather in 1939 and has been a popular destination for Staten Islanders for years.

Generations of borough residents have traveled over the Verrazano-Narrows Bridge for the eatery's famous square pizza slices, spumoni, generous portions of pasta and heaping piles of antipasto.

The Spumoni Gardens featured prominently in a 2011 mob case with Staten Island ties, when federal authorities alleged a family feud over pizza turned violent when a reputed mobster defended his in-laws' recipe by extorting a Staten Island pizza maker whose pies were apparently too similar to the ones served at L&B.
