I just literally watched a programme where a young girl had gone missing and they called off the search after two days and locals were up in arms about it. The investigators explained why they did so.... Whilst LE don't like ground searches done by members of the public AT ALL, they tend to accept them in the first place whilst time is of the essence. After the initial hours and days, they very often ask people to stop doing ground searches. The time for 'healthy return' has sadly passed and now they concentrate on the investigation and potential discovery of a crime scene which needs to be as intact as possible.
It doesn't mean they've stopped looking; it means they're looking in a different way. They're piecing together clues and information, rather than asking people to rake over land and potentially destroy evidence and/or have the perpetrator in a position to insert themselves into a crime scene/search party etc.
It's not unusual for LE to call off search parties and concentrate on their own, controlled searches. I don't see this as a problem at this stage. Although, like anyone, I of course hope for news soon.
As for FG, time and forensics will tell...
