A New Jersey police lieutenant was slapped with a 50-count indictment for allegedly swiping huge amounts of drugs from an evidence room — and making $600,00 in fishy bank deposits.

Kevin T. Matthew, 48, of Cedar Grove, has been suspended from his job at the Bergen County Prosecutor’s Office since December 2023, when he was arrested for taking the seized narcotics out of the office’s evidence room.

On Wednesday, the state attorney general’s office announced the wide-ranging indictment that charged Matthew with stealing cocaine, heroin and fentanyl marked as evidence — and in quantities “consistent with an intent to distribute those substances,” officials said in a statement.

Matthew’s alleged crimes — committed between January 2019 and November 2023 — included bank deposits that added up to about $600,000, according to the state attorney general’s office.

This money — which he broke into small increments so as to not trip the banks’ federal requirement to report transactions of more than $10,000 daily — was “not derived from or traceable to his salary and compensation as a sworn law enforcement officer,” the AG’s office said in a statement.

“The alleged misconduct by the defendant represents a stunning, tremendous disservice to the public,” Attorney General Matthew Platkin said in the statement.

“This case highlights the corrosive effects that corruption can have on public safety and trust,” he continued. “Instead of making Bergen County safer, the indictment alleges the defendant repeatedly withdrew from the evidence vault large amounts of dangerous drugs that had already been seized by law enforcement.

“This alleged conduct was a betrayal of this officer’s colleagues, his agency, his community, and his oath, and the grand jury’s findings reflect the severity of this alleged behavior.”

Matthew’s attorney, Charles Sciarra, said his client maintains his innocence and insisted the matter would be “vigorously defended.”

He also claimed the attorney general’s office has a “documented disastrous track record of recent failed investigations and prosecutions and a known bias against law enforcement.”

“Approximately 16 months ago, this attorney general’s office dragged my client’s name through the media mud,” Sciarra wrote in a statement. “Sixteen months later, they release a lengthy indictment that gets us no closer to the alleged conspiracy, whose alleged participants remain a mystery.

The AG’s probe into the veteran cop was first revealed by The Post in November 2023 and has been a black mark on the agency’s reputation.

Led by Mark Musella, the office is the top law enforcement agency in Bergen County, a wealthy region of just under a million people in the Garden State’s northeastern corner.

The office investigates major crimes and oversees each of the county’s 76 police departments. It answers only to the AG’s office, which is the top police agency in New Jersey. 

Matthew worked in the office’s Special Victims Unit, not narcotics — but due to his rank and position, he could still access law enforcement databases laden with info about narcotics cases and seized evidence, the statement said.

He’d parse through those databases, prosecutors said, and occasionally request evidence from proceedings he wasn’t involved in.

Then he’d allegedly sign out and remove the coke, heroin or fentanyl — which had already been tested by the State Police lab for use in court.

But when he’d bring the drugs back, there was some missing, the state said.

Matthew allegedly did this several times, stealing drugs related to nine different criminal cases.

At the same time, Matthew allegedly made a series of cash deposits at several different banks — none of which could be traced back to his county paycheck.  

The indictment — handed down by a Trenton grand jury — said Matthew didn’t report any of that income on his taxes.

The lieutenant has been charged with a litany of crimes, including financial facilitation of a criminal activity, possession with intent to distribute, official misconduct, tampering with public records, filing fraudulent tax returns and other drug and financial crimes.

If convicted, Matthew faces decades in prison and hefty fines.

When he was arrested, investigators found two razor blades in his office — which later tested positive for cocaine, authorities said.

He was also caught on camera coming and going from the agency’s Paramus headquarters toting bags big enough to carry the narcotics he’d signed out.

At the time of his arrest, Platkin called Matthew’s alleged conduct a “shocking and brazen disregard of the law by a high-ranking officer who was sworn to uphold the law.”
