Terrence Diamond, 46, described by police as the ringleader of the operation, was arrested Oct. 27 along with his brother, 41-year-old Terrell Devorae Diamond, and 37-year-old Theodore Cobbs. All three were booked into the Glendale City Jail without incident, according to Public Information Sgt. Justin Ramsay.

"He's serving as the ringleader of this racketeering and drug distribution network," Ramsay said.

According to a direct complaint filed in Maricopa County Superior Court, all three men are charged with illegal conduct of an enterprise, a class 3 felony. Cobbs also faces charges of transporting or selling dangerous drugs and two counts of conspiracy.

The investigation began in February 2026, when Glendale narcotics detectives and the DEA Phoenix Taskforce started tracking the organization using surveillance, court-authorized wiretaps and coordination with other agencies. In all, authorities seized 335 pounds of methamphetamine and fentanyl tied to the group.

Court documents link the organization to two major seizures. In July 2026, Utah Highway Patrol and the DEA recovered more than 200 pounds of methamphetamine in Utah. Then, on Sept. 7, 2026, investigators intercepted a shipment moving through the Phoenix area: Cobbs and other members left Phoenix in two rental vehicles, and a courier was stopped in a traffic stop. Investigators seized two large suitcases holding about 135 pounds of a white crystalline substance that field-tested positive for methamphetamine, along with several pounds of marijuana.

"They have an elaborate system," Ramsay said. "They're using rental vehicles, moving vans, things of that nature. And they're transporting massive quantities of methamphetamine and fentanyl across the United States. Most of this stemming from the Phoenix metro area."

When investigators executed search warrants at two residences associated with Diamond on Oct. 27, with help from the Glendale police SWAT team, they seized about $50,000 in cash, a rifle and additional evidence.

According to court documents, Cobbs was interviewed after being read his Miranda rights and repeatedly said he could not remember the events in question. He initially denied leaving the state with his co-defendants or driving a rental vehicle out of state — statements that documents say were contradicted by physical and electronic surveillance conducted over the prior nine months. Cobbs later admitted he would drive rental cars for a co-defendant across the country but said he did not remember why or know who rented the vehicles.

Ramsay said the investigation is ongoing and that he was limited in what he could share. He stressed the human toll of the drugs involved.

"This is 335 pounds of meth and fentanyl," he said. "This is killing people on our streets."

He credited cooperation among agencies and the patience required to build a case of this scale.

"This began in February. So since February we've been on this, we've been intercepting these drug loads," Ramsay said. "There's wiretaps, phone taps; there's a plethora of investigative skills and knowledge that goes into something like this, and they take time to build."

Ramsay said the work would continue.

"Our partners at the DEA, as well as Glendale Police Department's narcotics unit, we're not gonna sleep until we get all the drugs we can off the street," he said. "We want to keep our community safe, and I think this speaks to us doing a pretty good job of that."
