They allegedly found 11 large bags of cocaine, a digital scale and a marijuana blunt at the home on Windham Loop near Marsh Avenue.

About 45 minutes later, cops forced their way into the Tottenville home of Santopietro’s dad and reportedly found a loaded TEC-9 semi-automatic pistol, a .32-caliber handgun, a .30-caliber rifle and almost 200 rounds of ammo.

A vial of heroin and Ziploc bags of cocaine were also confiscated, sources said.

Meehan admitted to police that he had smoked pot shortly before driving, according to court papers.

He was charged with driving under the influence and leaving the scene of an accident, said the DA spokesman.
