"Mr Jubelin's barrister, Margaret Cunneen SC, put it to Detective Beacroft that a commander of the homicide squad, Scott Cook, said to her the investigation was "a waste of time" and police would "never get anyone for this".
"That's possibly something that was said," the witness replied.
Detective Beacroft on Thursday said she believed Mr Savage was no longer an "active" person of interest, despite there there being nothing which could rule him out.
Mr Jubelin's case was set down for five days, but is likely to be extended into next week."

JMO - I really don't believe Detective Beacroft, while being questioned by Jubelin's Defence Barrister Margaret Cunneen SC, was necessarily inferring that Savage should still be under suspicion!
