Suffolk County police officers arrested a man who works as an evening custodian for the Commack School District after a search found he had a stash of illegal guns and drugs inside his Patchogue home.

Patrick Musumeci, 30, was arrested Feb. 6 by police officers and faces 24 drug- and weapons-related charges.

Following an investigation, Suffolk’s 5th Squad Special Operations Team and Emergency Section Service officers along with 5th Precinct Gang Unit officers executed a search warrant on Musumeci’s home on Wilmarth Avenue at approximately 5:35 a.m.

In the raid, officers found 16 guns inside the Patchogue home, including one Glock semiautomatic handgun, a Taurus semiautomatic handgun and four assault rifles, with ammunition. Two of the guns, a Smith & Wesson pistol and Ruger pistol had both previously been reported stolen. In addition to the guns, officers seized five sets of brass knuckles and a switchblade.

In addition to the weapons, Suffolk County police officers seized quantities of both prescription opiates and illegal drugs from the Patchogue home. The drugs found included oxycodone, Xanax, concentrated cannabis, marijuana, morphine pills and packaging materials.

Musumeci is charged with three counts of criminal possession of a controlled substance in the third degree, criminal possession of a controlled substance in the fifth degree, six counts of criminal possession in the seventh degree, two counts of criminal use of drug paraphernalia in the second degree, criminal possession of marijuana in the fourth degree, five counts criminal possession of a weapon in the third degree, four counts criminal possession of a firearm, criminal possession of a weapon in the fourth degree and one count of grand larceny in the fourth degree.

Commack school officials reacted to news of Musumeci’s arrest by posting a letter to district residents on its website.

“The district has found no evidence to date that he ever brought a weapon or drugs onto school property,” reads the district’s statement. “To date, we have not found any suspicious activity on school property.”

Prior to being hired, Musumeci was fingerprinted and underwent a background check by New York State, according to the district. He was cleared, and state law would have required the district to be notified of any subsequent arrests, of which they claim to have received none.

Commack school officials said the district also has conducted an extensive search of the employee lockers, areas of the buildings the evening custodian was responsible for overseeing and reviewed buildingwide video footage in the wake of the allegations.

“The district and its outside security consultant will continue to review its safety and security plans and determine whether or not additional precautions are warranted,” read the district’s statement.

Musumeci was arraigned Feb. 7 in 1st District Court in Central Islip. He was ordered held in lieu of $100,000 cash or $200,000 bond, which had not been posted as of Feb. 13.

Commack school officials said their investigation into the matter is ongoing and the district is fully cooperating with the Suffolk police department.
