In a lengthy statement, Brian Walshe’s lawyer, Tracy Miner, claimed that the media «has already tried and convicted Mr. Walshe.»

“It is easy to accuse a crime and even easier to say that a person committed that crime. It’s a much more difficult thing to prove, we’ll see if the prosecution can do it. I am not going to comment on the evidence, firstly because I am going to deal with this case in court and not in the media. Second, because the prosecution has not provided me with any evidence,» Miner said.

Miner asked the court to have Brian Walshe released from custody, where he has been since his arrest on January 8 on charges of misleading an investigation, which the judge denied.

Brian Walshe is being held without bail pending arraignment. He is next due to appear in court for a status hearing on February 9.
