Aug. 18--A Fort Worth man was arrested Thursday for allegedly manufacturing and distributing of synthetic opioids in Burleson, apparently the largest quantity ever to be found in North Texas.

Officers from the Johnson County Stop the Offender Program Special Crimes Unit were contacted by the Burleson Police Department on June 15 in reference to possible illegal narcotics in the 1300 block of Northwest John Jones Boulevard.

Upon arrival, investigators set up covert surveillance and observed a white male entering into the business where the illegal narcotics were reported to be located, according to reports.

STOP agents made contact with and identified the subject as Brady Wirth Gaisser, 29, of Fort Worth.

Gaisser was told of the allegation and gave consent to search the building.

During the consent to search, a quantity of high-grade marijuana was located along with one of the largest Carfentanil processing labs ever located in North Texas.

According to the U.S. Drug Enforcement Administration, Carfentanil is a synthetic opioid that is 10,000 times more potent than morphine and 100 times more potent than fentanyl, which itself is 50 times more potent than heroin.

These substances can come in several forms, including powder, blotter paper, tablets and spray -- they can be absorbed through the skin or accidental inhalation of airborne powder.

Because of the extreme danger of Carfentanil, no field test could be performed and Gaisser was arrested and booked into the Johnson County Jail for possession of marijuana over 4 ounces but less than 5 pounds, a state jail felony.

He bonded out on the charge the next day, and, according to reports, moved his family from the city of Burleson to an unknown location.

Over 30 drug exhibits were processed from the scene and 21 drug exhibits were sent to the Texas Department of Public Safety Crime Laboratory in Waco.

For health and safety reasons the laboratory only tested two of the 21 exhibits submitted.

"This large amount was even new for the laboratory," STOP Commander Larry Sparks said. "It is just not common to seize this large amount of Fentanyl or Carfentanil."

One of the drug exhibits Gaisser had in his possession at the time of his arrest tested positive for over 20 grams of Carfentanil, according to reports.

The second container tested returned as over 500 grams of Carfentanil.

The other drug exhibits were a hodgepodge of different narcotics, including multiple containers believed to be liquid Carfentanil, powder Carfentanil, bags of ecstacy, numerous containers of tetrahydrocannabinol wax, boxes of Tramadol, Tapentadol and several synthetic controlled substances.

Upon receiving the lab results, an arrest warrant was issued for Gaisser for manufacturing and/or delivery of a controlled substance PG1, over 400 grams, first-degree felony.

Judge William Bosworth of the 413th District Court set the bond at $1 million.

On Thursday, investigators were able to track Gaisser down to a location in Tarrant County where he was taken into custody for the warrant. At the time of his arrest, Gaisser was with his wife and three children.

More exhibits were seized as evidence and are believed to be Fentanyl or Carfentanil.

He was transported and booked into the Johnson County Jail. Additional charges are pending lab results.
