Former Middletown police sergeant sentenced to 5 years in ghost-gun case
David Ringkamp pleaded guilty to second-degree conspiracy to commit official misconduct after prosecutors said he helped a Millstone vape shop owner move illegal ghost-gun kits away from watching police.
A former Middletown Township police sergeant has been sentenced to five years in state prison for abusing his position as a police officer, the Monmouth County Prosecutor's Office said Oct. 6.
David Ringkamp, 45, formerly of Union Beach, was sentenced by Superior Court Judge Jill G. O'Malley on a charge of second-degree conspiracy to commit official misconduct. He pleaded guilty in March, according to the prosecutor's office.
Prosecutors said the case began in December 2021, when New York State Police watching a gun show in Pennsylvania saw Nicholas D'Ambrosio, 35, of Millstone, buy several kits used to build so-called ghost guns, untraceable firearms assembled from parts, which are illegal in New Jersey. New York troopers followed D'Ambrosio to his vape shop, JR Vapors, in Millstone and contacted the New Jersey State Police.
According to prosecutors, Ringkamp and another person then arrived at the shop, and D'Ambrosio hid the gun parts in Ringkamp's car. When police pulled the car over, Ringkamp identified himself as a Middletown sergeant. Prosecutors said he had agreed to help D'Ambrosio get the parts out of the shop after D'Ambrosio realized police were watching him.
Police found the ghost-gun kits, cocaine and dozens of methamphetamine pills in the car, prosecutors said. A search of the shop turned up more than 25 pounds of marijuana and marijuana edibles and an assembled ghost gun, and a search of Ringkamp's home days later found cocaine and anabolic steroids.
Prosecutors said Ringkamp had contacted the New Jersey State Police, identified himself as an officer and lied to get information about the investigation, and deleted text messages to hinder it. He was also charged with using police databases dozens of times over three years to look up D'Ambrosio and others with no legitimate reason, according to the prosecutor's office.
D'Ambrosio was sentenced in August 2024 to eight years in state prison after pleading guilty to drug and ghost-gun charges, prosecutors said.
