Denison Police said three people were arrested and 500 grams of methamphetamine were seized Wednesday, after local and federal law enforcement officials executed a narcotics raid on a Denison home.

In an emailed statement distributed Thursday, the Denison Police Department said the operation was conducted at approximately 10:30 a.m. and targeted a residence on Smith Drive. Citing the ongoing investigation, Lt. Mike Eppler said he could release few details, but said officials from the U.S. Marshals Service, the Denison Police Department, the Sherman Police Department and the Grayson County Sheriff’s Office descended on the residence after they were notified of potential criminal activity at the address.

“Getting narcotics off the street certainly makes the community safer, especially in that amount,” Eppler said of the drugs seized.

Terry Lynn Pye, 44, was arrested on a federal warrant and charged with conspiracy to manufacture and distribute methamphetamine. Donovan Shane Carroll, 49, was arrested on a Grayson County warrant for failure to appear and evading arrest. Charles Wayne Phillips, Jr., 38 was arrested on unspecified warrants out of Denison. A search of the Grayson County jail records showed Pye and Carroll remained in custody Thursday, but listed no bond or attorney information. Phillips was booked into the Denison city jail. It was unclear whether he remained in custody Thursday and a booking photo for Phillips was not immediately available. It was also unclear whether he had appointed an attorney to represent him.

Four other unidentified people were located inside the home during the raid. Though Eppler said the four individuals were not arrested Wednesday, the department’s emailed statement indicated that at least four of the seven total people inside the home would likely be charged with felony drug possession. An approximate street value for the drugs recovered was not immediately available Thursday.

Eppler said additional information related to the investigation may be released in the coming days and encouraged members of the public to notify law enforcement if they observe activity that appears criminal in nature.

“If anybody has any information about illegal activities, please let us know,” Eppler said. “And you can always remain anonymous.”
