A 28-year-old man was arrested for working for a 19-year-old man who ran a large-scale, nationwide drug operation in the Salt Lake Valley.

During a 13-month undercover investigation, law enforcement discovered N'twydamla Cook was illegally selling large amounts of marijuana, dabs, THC cartridges, THC edibles, cocaine, acid, and ecstasy, court documents state.

Andrew Diep consistently visited his several P.O. boxes across the Salt Lake Valley and was seen putting the packages into Cook's car.

Cook would then post on his Snapchat account about having "re-upped" and displayed a list of available drugs. He also advertised fraudulent driver's licenses and firearms, some of which he kept for himself.

Postal investigators intercepted several packages addressed to Diep, which contained THC vape cartridges and THC edibles. During one search, investigators found approximately $120,000 worth of THC cartridges. Court documents state Diep received an estimated 100 packages.

Authorities located evidence of several large payments to Diep from Cook.

Diep is a part-time employee at an unspecified company and leases his apartment while he shares a high-end apartment with Cook. He also owns a Harley Davidson motorcycle and a 2013 Toyota Tacoma with no lienholder, court documents state.

During a search of the apartment, detectives found a semi-automatic handgun, large amounts of ammunition, $1,840 in $20 bills, marijuana, THC dabs, drug paraphernalia, multiple "pay-owe" sheets and detailed lists of Cook's drug operation.

Based on the evidence collected, Diep was arrested and booked into jail on the following counts: pattern of unlawful activity, knowingly producing/dispensing/manufacturing a controlled substance, possessing a dangerous weapon by a restricted person, use or possession of drug paraphernalia, money laundering and possession or use of a controlled substance.

Cook was arrested for four counts of distributing a controlled substance, forgery, reckless endangerment and engaging in continuing criminal enterprise, court documents state.

Cook admitted during a police interview to using the Snapchat accounts to sell narcotics and fraudulent driver's licenses. The 19-year-old said he was in charge of the Utah drug sales for an organization he works with. When asked about the firearms, Cook said he kept the AR-15 rifles for protection because he had been robbed in the past.
