Sitting on a bed, Danielle Ruiz watched Luis Pereira and his roommate in the kitchen. They stood with their backs to Ruiz and filled a milk jug with alcohol and another mysterious substance.

Ruiz met with Pereira earlier that night in October 2010 outside Spannk, a Southwest Second Street club, after she left a costume party. Pereira invited Ruiz -- and others, he said -- to his place. Ruiz always enjoyed his parties, so she went, still wearing a black sequin jacket and a pink tutu. When she arrived, though, the apartment was empty.
