The silence is deafening. It is also interesting that not a single formal charge has been brought.
Over 170 people have had their lives ruined. Totally destroyed. Most of them are clearly not guilty of any crime other than being at Twin Peaks at the wrong time.
How long can they keep the lid on this? Headshake.
Grand jury doesn't meet until October (which I know is right at hand). Texas law allows detention without indictment for over half a year. An accusation alone is enough to support detention. In some cases, detention can be mitigated with bail, but bail conditions, including curfew, association limitations, forfeit 4th amendment rights as to search and seizure being supported by warrant, etc. almost always attach to being out on bail.
