I've never understood the role of Murat, but wasn't he officially "cleared" in the same way Kate and Gerry were? Didn't he also win a court battle with the T7 which concluded there was no evidence to link him to Madeleine's demise?
There was no court battle with the T7, but three of them returned to Portugal to confront him at the police station on 11th July;
RECORD OF CONFRONTATION
---- On 11 July, at 10:00, in the premises of the Department of Criminal Investigation of the Portimao Judicial Police, before me, Paulo Ferreira, Inspector, and Dr. Guilhermino Encarnacao, Deputy National Director of Judicial Police, appeared the defendant ROBERT JAMES QUERIOL EVELEIGH MURAT, already identified in the file, in order to proceed with his interrogation. Following on [prior] interrogatory work and contradictions having been seen between that which the defendant said and that of the witnesses, RACHEL MARIAMMA JEAN MAMPILLY, RUSSEL JAMES O'BRIEN, and FIONA ELAINE PAYNE, all also duly identified in the file, given that in the depositions of these people there exist clear contradictions with the answers of the defendant, this present work proceeded.
