They wanted to hear what she had to say. She didn't have to say what she did, she wasn't coerced.
So either all the essex police were lying, the raid teams, coroners, julie, most of the bamber family & there are still coverups to this day .. so that's courts, witnesses, anyone with the PII material.
Or
Jeremy Bamber is a liar.
And Rochford.
She did come forward. Suspicion was already falling on Jeremy Bamber (at least I've been told this by an offcier but he may be saying that suspicion was already falling on bamber because he's embaressed it wasn't) but then she came forward with a phone call at first.
She withheld her name/information.
But it was traced back to her, and then the fight began to get to the truth.
