An investigation into narcotics trafficking in Manteca Police led detectives to a house in Lodi where a large cache of weapons and drugs were discovered.

Tony Lopez, 19, was arrested after the Manteca Street Crimes Unit served a search warrant a home in Northern San Joaquin County they believes was tied to his operations in Manteca and discovered a short-barreled rifle and a 9mm handgun – both of which were manufactured so as to avoid the placement of a serial number – as well as a trove of narcotics that included 2.3 pounds of methamphetamine, 10.2 grams of cocaine, more than a quarter-pound of processed marijuana and more than $3,200 in cash.

According to Manteca Police, the investigation began in Manteca and “due to the complexity of narcotics investigations” led officers to a secondary residence in Lodi where they discovered the drugs, cash, and weapons.

Lopez was booked into the San Joaquin County Jail on three drug-related charges – two of which are felonies – as well as a host of weapons charges including illegally possessing an assault weapon, the possession of a large capacity magazine, and the manufacturing of an assault weapon. He is also facing charges of possession of a controlled substance while armed with a loaded firearm, and possession with the intent to sell a controlled substance.

He is being held on $350,000 bail and is due to appear in Department C of the Lodi branch of the San Joaquin County Superior Court on Monday, Feb. 10, at 12.15 p.m.
