WACO, Texas (AP) — Prosecutors say 18 members of the white supremacist Aryan Brotherhood of Texas are going to prison for running a drug ring.

All of the men and women gang members sentenced Wednesday in Waco pleaded guilty to conspiracy to possess with intent to distribute methamphetamine.

The sentences range from nearly 16 years in prison to 21 months behind bars.

Authorities made undercover drug purchases as part of the nearly yearlong investigation. Law officers recovered drugs, firearms and cash.

The convicted felons are from Belton, Temple, Gatesville, Lampasas, Nolanville and Waco.
