In his excellent book "My search for Madeleine", Jon Clarke reported that one of the SIM cards found in 2016 in Brückner's factory at Neuwegersleben, Germany, belonged to "a British man whose holiday apartment in Praia da Luz had been robbed around the time that Maddie was missing".
I think he is referring to the burglary of "Casa María" in February 2007, some three months before Madeleine's abduction.
"Casa María", that also could be called "4A".
PostScriptum (October 18, 2023): A very reliable source told me that the burglary cited by Jon Clarke took place in August 2007, and was not the burglary of "Casa María". Was Brückner robbing at the Praia da Luz zone three or four months after the abduction? Very strange if he was the abductor.
