A nine-month joint narcotics investigation between the Stephenville Police Department and Erath County Sheriff's Office has now led to the arrest of nine suspected drug dealers in two days.

Late Tuesday night three suspects, Reginald Cook, 30, Jeffrey Owens, 30, and Cortney Young, 29, turned themselves in to authorities. Investigators are still searching for Brian Patrick Butz, 42, Donjel Lamont Walker, 26, and Nicole Rachell Cehand, 22.

"We are still actively searching for the remaining suspects and hope they will either turn themselves in or someone will tell us where they are," Police Chief Patrick Bridges said Wednesday.

On Tuesday afternoon, eight of the 17 suspects caught in the sting and charged with more than 25 counts of drug trafficking and other offenses were arrested including Marcus Marcoot,19, Steven Ray Crawford, 32, Detauras Hopkins, 32, Everett Brooke Williams, 36, James Charlton Carr, 25, Tasha Lashae Bryant, 24, Bradley Keith Collins, 19, and Allana Darlene Spencer, 25.

Three additional suspects, Samuel Edward Lynch, 24, Stephen Frank Quintero, 27, and one suspect authorities are not ready to identify, were already in jail on other charges.

Sheriff Tommy Bryant called the investigation the longest undercover operation he has ever been involved with, and expects the arrests to slow down drug trafficking in Stephenville and Erath County.

Crime Stoppers is offering a reward for information leading to the arrest of the suspects still at large. Anonymous tips can be made by calling 254-965-CASH.
