PARSIPPANY — Morris County Prosecutor Robert Carroll, Chief of Detectives Robert McNally, and Lincoln Park Police Chief John Cifelli confirmed an arrest following a narcotics investigation that yielded the seizure of various controlled dangerous substances (CDS) and firearms, which resulted in the arrest of three defendants.
On November 13, 2025, investigators carried out the execution of search warrants at a residence in Cedar Knolls in Hanover Township, a residence in Parsippany-Troy Hills, four vehicles, and a storage unit in Parsippany-Troy Hills.
A search of the Cedar Knolls residence resulted in the seizure of approximately 24 grams of suspected ketamine, approximately 10 grams of suspected cocaine, approximately 20 pills of suspected MDMA, over 6 ounces of suspected marijuana, and drug paraphernalia indicative of CDS distribution, as well as nearly $18,000 in U.S. Currency, which are alleged to be CDS proceeds. A search conducted of a Nissan Altima known to be associated with Jeremy Mayes yielded the seizure of a Glock 43 handgun, which was confirmed stolen out of Mississippi.
A search of the Parsippany-Troy Hills residence resulted in the seizure of approximately 64 grams of suspected cocaine, a loaded revolver, and drug paraphernalia indicative of CDS distribution.
It is alleged that Jeremy Mayes, Casey Young, and Adrian Schwerdt-Oneil operated a CDS distribution network in Morris County between September 1, 2025, through November 13, 2025. Mayes and Young were detained by officers on November 13, as Young arrived at the Cedar Knolls residence driving a Madison DPW truck, while being employed by the town of Madison.
During the arrest of Young, he was found to be in possession of cards identifying a storage unit in Parsippany. Following the approval of a subsequent search warrant, the storage unit was searched, which yielded a loaded Glock 31 handgun, approximately 5 tabs of suspected LSD, two bags of suspected psilocybin mushrooms, numerous pills, and drug distribution paraphernalia including a drug ledger.
