I don't believe there will be any consideration for flight risk because, by Statute, BM really isn't eligible for bail release -- not to be confused with all defendants having a right to a bail hearing.
IMO, this is what we should expect for the August 9, 10, preliminary/PEPG hearing:
(3) In any capital case, the defendant may make a written motion for admission to bail upon the ground that the proof is not evident or that presumption is not great, and the court shall promptly conduct a hearing upon such motion.
At such hearing, the burden shall be upon the people to establish that the proof is evident or that the presumption is great. The court may combine in a single hearing the questions as to whether the proof is evident or the presumption great with the determination of the existence of probable cause to believe that the defendant committed the crime charged.
In other words, establishing the existence of probable cause will end the bail question once and for all.
One of the reasons BM's defense asked to get the voter fraud charges on the calendar (later Aug after preliminary/proof evident, presumption great) was to preserve any rights BM might have to bail for a charge which is a bailable offense. They are being thorough in event of a fluke with his murder complaint.
