BAKERSFIELD, Calif. (KGET) — A man arrested in Bakersfield is among 21 people indicted in a large-scale operation spanning multiple states that resulted in the seizure of dozens of guns and more than 200 pounds of drugs — including thousands of pills containing fentanyl.

The arrests Tuesday followed a 15-month investigation targeting a street gang in the Hamilton Park area of Dallas, according to the U.S. Drug Enforcement Administration. The gang ran a highly-efficient drug organization, authorities said during a press conference Wednesday in Texas.

Those in custody, plus one person who remains at large, face a 19-count federal indictment as a result of Operation Shut Down Corner, DEA officials said.

Demetric Watson was identified as the man arrested in Bakersfield on charges of possession with the intent to distribute drugs. The DEA said some defendants face up to 40 years in prison if convicted.

Authorities seized 37 guns, 220 pounds of drugs and $420,000 in assets, according to the DEA. Cocaine, crack cocaine, methamphetamine, marijuana and counterfeit pills containing fentanyl were taken.

Chad Meacham, U.S. attorney for the northern district of Texas, said fentanyl is one of the deadliest drugs on the street. It causes thousands of deaths every year and has no place in any community, he said.

Drug trafficking and violence are intrinsically related, said DEA special agent in charge Eduardo A. Chavez, and impact all members of society. People who obey the law and simply want to live and raise a family in peace instead end up fearing for their lives.

Chavez said he once heard Hamilton Park described as a forgotten neighborhood. People living there were 11 times more likely to be the victim of a violent crime than other Dallas residents.

“That stops now,” Chavez said. “These street corners will be clean. We back the community of Hamilton Park.”

In addition to Watson, those charged only with conspiracy to possess with intent to distribute drugs are Randall Hoskins, aka “Rambo,” Rosie Bush, aka “Shanta,” Kemerra Gilbert, Jerome Brown, Jerome Miller, Damone Dixon, Michael Gipson, aka “Grip” and Addison Cole, aka “Addy” or “Scat Back,” according to the DEA.

The defendants charged solely with unlawful use of a communication facility are Jimmy Reedy, aka “UM-8033,” Staecey Logan, Bridney Fannin and Kimmy Blanton — identified as the fugitive by DEA officials. Sergei Gharpetian and Tigran Mkrtchyan are indicted on a charge of conspiracy to launder money.

Devonte Thursby, aka “Wook” and Tamara Cashaw are indicted on charges of conspiracy to possess with the intent to distribute drugs and unlawful use of a communication facility, according to the DEA. Reginald Lamar Denson and Jahmear Chance Jackson are charged with conspiracy and possession with the intent to distribute drugs and possession of a firearm by a convicted felon.

Quientin Titus, aka “QT” or “Quick Trip,” is charged with maintaining a drug-involved premises and conspiracy to possess with intent to distribute drugs, officials said. Lastly, Brian Williams is charged with conspiracy and possession with intent to distribute drugs and possession of a firearm in furtherance of a drug trafficking crime.
