What did they ask Damascene about Immaculee?

From the text:

"Where is your pretty little sister?" the killers had asked my brother. "Where is Immaculee? We've sent the bodies of the other cockroaches in your family, but we haven't had our fun with her yet.... where is she? Tell us and we'll let you go; don't tell us and we will spend all night killing you. Tell us where Immaculee is and you can walk away." (Page 175)
