The Grayson County Sheriff’s Office arrested two people, one suspected of dealing methamphetamine, after a search warrant was executed Thursday at a Sherman residence.

Kimberly Wrench, 38, of Denison, and Brian Black, 37, of Sherman, were arrested on drug possession charges after authorities searched Black’s residence in the 700 block of Patricia Drive for narcotics. In the affidavit for the search warrant, which the Herald Democrat obtained Friday, investigators received anonymous tips that were corroborated by a confidential police source. The tips alleged that Black was in possession and distributing meth from his residence.

The 15th District Court issued the search warrant Wednesday afternoon, and it was executed by sheriff’s office investigators and Sherman Police at about 6 a.m. Thursday. While police searched the residence, they located an explosive device at the property.

The sheriff’s office contacted the Bureau of Alcohol, Tobacco, Firearms and Explosives, who in turn called in the Plano Police Department Bomb Squad. Grayson County Sheriff’s Lt. Sarah Bigham said in a news release on Friday that the explosive found at the scene was a small pipe bomb like device. Bomb squad personnel safely detonated the device at about 10:30 a.m. Thursday.

According to the affidavit, which was prepared by a sheriff’s office investigator, police searched the property because they had evidence to believe it held meth and records of drug trafficking. The affidavit described the residence as including a white travel trailer and a shop garage next to it. The tips alleged that Black was in possession of scales and baggies and planned to sell meth from his residence and also deliver it. The tips also gave specific details where Black concealed the meth at the residence.

The confidential source, which the affidavit notes had a proven track record of providing information leading to arrests and drug seizures, told the investigator that Black was in possession of meth and planned to sell it at that location. Black also allegedly indicated to the source that he planned to acquire more meth to distribute.

The affidavit requested to execute to warrant without knocking or announcing police presence as doing so might jeopardize the investigation or put officers into danger. Based on the investigator’s experience, the affidavit states that narcotic dealers often posses firearms to protect their trade, and the anonymous tips indicated Black was in possession of firearms. The confidential source observed a surveillance system, which could provide early warning to Black, thus requiring police to enter unannounced, according to the affidavit.

According to the inventory of the items collected from the scene, police took into evidence the following: a cellphone, a cellophane bag containing meth, shotgun shells, a plastic bowl with meth baggies, a revolver, .22-caliber bullets, a digital scale, gun powder and a metal pipe.

Wrench was charged with possession of a controlled substance between 4 grams and 200 grams in a drug-free zone, and bond was set at $15,000. Black was charged with possession of a controlled substance less than 1 gram and for an outstanding warrant for possession of a controlled substance between 4 grams and 200 grams in a drug free zone. Bond was set at $7,500 for the first charge and $50,000 for the outstanding warrant.

When asked if any additional charge will be sought in connection to the explosive device, Bigham said it’s possible.

“They may be in the future, but it is unclear at this point if those charges will be on the state level or federal charges,” Bigham said via email.
