Does the issue about the condition of his release relating to where he will reside imply that his parents will not allow him to live at the house? Does this imply that they believe he is involved in some way based on the circumstantial evidence the general public may not be privy to?
That could be possible Lego, but it's probably more that he'll need a different residence than where he was residing (and also, due to the fact that it's become an area for investigation by LE). I'm thinking that the Crown will be asking for a residential surety, and possibly that house arrest be included. So, this would require a surety that is able to monitor his activities 24/7, or in conjunction with others - like an employer if he was employed, and then, an exception given to be out for work purposes, and/or a family member or friend who knows him well. If more than one surety steps up, the better the plan will be in the judiciary's eyes, and of course, that they present well on the witness stand when questioned by both the Crown and defence.
I am leaning towards the fact that there will be very strict terms for his release, and probably more than the average pledge of money for a surety. (The Crown can go back on both DG and the surety/sureties for the amount of money pledged if he should breach any of his bail conditions.) And, don't forget, the Crown can show his past may dictate his future - the Crown is going to say he's fled before, and so, even with roots in the community (his parents), he is at high risk for flight.
It will be interesting to see if his parents come to his aid or not, as we have not seen or heard from them, other than from their pastor, who said, they are doing as well as can be expected under the circumstances. And, if so, or not so, who will, and where the plan is for him to live. Defence has to propose a very good plan in order for him to be released. Obviously, nothing could be put in place for a bail hearing today, so they've remanded him until Friday, when maybe defence will have something in place for DG.
Having said that, he could have more than one surety. For example, one or both of his parents, or another family member or friend. This doesn't mean that all the sureties must live with DG. One will suffice, but all sureties would be responsible for ensuring he attends his court dates, and follows all the terms of his conditions of release set by the justice of the peace.
I work in the courts here in Ontario, so I know a bit better how things work. I imagine Alberta is much the same as Ontario.
Oh, and just an addendum - whether the charges will be read out in court or not - defence probably will waive reading of the charges, and the accused, DG, if asked, would indicate he understand the charges - it that hasn't happened already, because a new charge was added, and would have come up today. If a bail hearing does proceed on Friday, the Crown will read in the facts, and so, it will be very interesting to see how much is revealed from the Crown synopsis, and what, if any, mention is made of the 3 missing family members. (sorry, I've messed up, and have had to edit a few times, lol!)
