Given we are led to believe ScW was steadfastly answering “no comment” in interview once arrested, then his only previous responses were the “man on the edge” and other earlier interactions with the police.
It could well be that the police also are building a clearer picture on where BW may be through the court testimony. @helenvic was there any sign of detectives in court beyond the usual uniformed police and prison service presence?
The police would have all the data from the phones.
They provided all the case information for the trial.
