HAMILTON, NJ --   A month-long investigation landed a seizure of a cache of drugs, a gun, and cash at a home on the border of Hamilton and Trenton, according to Mercer County Prosecutor Angelo J. Onofri 

In a Wednesday statement Onofri announced that detectives with the Mercer County Narcotics Task Force (MCNTF) executed a search warrant at a residence in the 100 block of Genesee Street allegedly utilized by the target of the investigation, Juan Marrero. 

After numerous attempts to gain entry to the residence made difficult by a fortified entrance, detectives secured the house at which point Mercer County Prosecutor’s Sergeant Joe Angarone utilized his K9 partner Bela to conduct a narcotics search.
