GREAT NECK, N.Y. (CBSNewYork/AP) — The son of a firefighter who died on 9/11 and another man face charges of menacing Long Island police with a gun.

Nassau police said Andrew Lelpi and Anthony Guerrero will be arraigned Monday on charges of criminal possession of a weapon and menacing a police officer.

Police found Lelpi outside a Great Neck glass business where they say he pointed a handgun at them Saturday. Police also found a .357 Magnum handgun and a 12-gauge shotgun at the scene.

Police went there after a Great Neck resident told them the two had threatened him over a money dispute.

Lelpi’s father, Jonathan, was a FDNY firefighter.

His grandfather, Lee Lelpi, tells Newsday 9/11 has altered many young people’s lives in terrible ways.

It’s not clear if the suspects have lawyers.
