The guy’s a tit. Think initially he was trying to help, but the confidence level he was claiming to have “I’ll find her in 5 minutes. She’s 100% not in the river” set my bullsh!t alarm off.
When he’s then speculating about the phone being a decoy, and saying he can advise police of where in the woods they should be searching, he was obviously overstepping his remit, and at that point is no more an expert than any other social media sleuth.
Fact that even this morning he’s going on telly because he’s getting criticism, speaks to a man with a big ego. Should be keeping his head down, not trying to publicly justify himself.
