No news. If the person who called from mobile phone number +351 916510683 to mobile phone number +351 912730680, on may 3, 2007, at 19:32, does not appear, the murder of Madeleine could go unpunished.
Maybe Bernhard P. or Michael T. could provide more data given their closeness to Christian B. at that time. The evidence of the death of Madeleine comes from material recovered by German police at Neuwegersleben since February, 2016. See this Bild news.
