I feel it's a positive update, too. I was particularly struck by this bit: 'an unprecedented amount of work taking place behind the scenes' - reassurance that LE are still very actively working on the case, not just letting it lie until the court appearance.
There was talk earlier of a particular female specialist being approached for help (sorry, can't recall the details/name) - does anyone with a better memory than me think she may be included in the 'search specialists as well as experts in forensics and oceanography' referred to?
