HOUSTON, Texas (KTRK) -- The brother of a kidnapping victim who was shot to death by an FBI agent during a rescue attempt wants a detailed account of what happened."I'm waiting for them to call me and to tell me how everything happened," said Ernesto Valladares.

Detail by detail."With his hands still bound with duct-tape, Ulises Valladares, 47, was shot to death by an FBI agent as they tried to rescue him from a home in northeast Houston on Thursday.
