OKLAHOMA CITY -- The sole survivor of a shooting that killed a woman featured on the HBO reality series "Cathouse" and three other people says he paid a Mexican mafia member $2,000 less than what was owed for drugs just hours before the shooting.

Jose Fierro testified Wednesday in the preliminary hearing for David Allen Tyner who is charged with six counts of first-degree murder.

He has pleaded not guilty.

The victims included 22-year-old Brooke Phillips who was featured on the HBO show.

Tyner is charged with six counts because Phillips and another victim were pregnant.

Fierro said he paid $16,000 to the Mexican mafia when members came to his home to collect $18,000 for drugs they had provided.

He said he escaped through a garage when gunfire broke out after Tyner came to the home.
