I'm local but I don't know the answer. My best guess is that it won't be released until arraignment, which is Wednesday. Another thought is that I believe he was booked at MCC, which is a federal prison, perhaps they have a different routine? Just guesses...
I'm curious as to why there is no (that I know of) arrest mugshot of this suspect some 3 days after the fact. It's unusual to me. Maybe different in CA but where I live it is available online after the booking has taken place with the booking information and bond info. Strange to me.
