Herman Vaughan and Katrina Davis each waived their detention hearing.
That means they'll stay in custody until trial.
Vaughan and Davis, along with 28 others, are charged with conspiracy to possess with intent to distribute a cocaine base of 280 grams or more.
They were arrested after a federal indictment was unsealed June 26.
Assistant US Attorney Brandon McCarthy says police asked the FBI to get involved with a drug investigation in Wichita Falls.
That investigation began before New Years Day in 2009.
McCarthy says most of the charges in this investigation stem from the Kemp Edition Posse, or KEP, a street gang.
He says the gang and some associates of the gang operated a drug ring selling mostly cocaine out of the Budget Inn Motel.
FBI officials hooked up a camera to a pole in the motel parking lot.
The camera recorded activity for more than a year.
McCarthy says most of the defendants were caught on camera selling drugs to undercover agents.
If convicted, each defendant faces a sentence of 10 years to life in prison, and up to a $10-million fine.
