GLENDALE — Three men face felony charges after a months-long investigation by the Glendale Police Department and the Drug Enforcement Administration that authorities say netted 335 pounds of methamphetamine and fentanyl, ABC15 reported.
Glendale narcotics detectives and the DEA Phoenix Taskforce began investigating the organization in February 2026, police said. Investigators allege the group was led by 46-year-old Terrence Diamond.
“He’s serving as the ringleader of this, this racketeering and drug distribution network,” Glendale police Public Information Sgt. Justin Ramsay told ABC15.
According to court documents cited by the station, investigators used surveillance and court-authorized wiretaps and believe the group moved drugs across the country in rental vehicles and moving vans while using encrypted communications.
Authorities tied the group to two large seizures. In July, Utah Highway Patrol and the DEA recovered more than 200 pounds of methamphetamine in Utah, police said. On Sept. 7, a courier was stopped during a traffic stop and investigators seized two suitcases holding about 135 pounds of a substance that field-tested positive for methamphetamine, court records say.
On Oct. 27, investigators served search warrants at two homes linked to Diamond with help from the Glendale SWAT team and seized about $50,000 in cash and a rifle, according to police.
Diamond, his 41-year-old brother Terrell Devorae Diamond and 37-year-old Theodore Cobbs were arrested without incident and booked into the Glendale City Jail, police said. A complaint filed in Maricopa County Superior Court charges all three with illegal conduct of an enterprise, a class 3 felony. Cobbs also faces drug transportation and conspiracy counts.
The charges are allegations, and the men are presumed innocent unless proven guilty in court. It was not immediately clear whether the men had attorneys who could comment on their behalf.
Ramsay said the investigation remains ongoing. “This is 335 pounds of meth and fentanyl,” he said. “This is killing people on our streets.”
