This HS says a bit more about what Mick had to say.
Reporters caught him as he was seen returning to the house just after midday.
(paraphrased)
He was relieved about the progress in the investigation, he has been cautioned by the police to not say anything further about the investigation, he asked the media to respect the privacy of the family, they are doing okay, they'll talk when it is time to talk.
Detectives in an unmarked car were seen at the house a bit later and went inside the house with Mick. (1:45pm).
