Portuguese detectives showed up to question prime suspect
CB soon after MM's disappearance, but he wasn't in when they arrived.
Disgraced former chief Goncalo Amaral, 60, who led the investigation in 2007, made the claim about Christian Brueckner (pictured) on Portuguese TV on Sunday night.

A proper investigation would have progressed to the phone dump where CB's phone traffic could have been evaluated in 2007 rather than when it was in 2013.
This was a case which had the potential to have been resolved in 2007 if the appropriate investigative procedure had been followed then. Sadly that didn't happen in a classic case of trying to fit the theory to the evidence.
