They are dead. Texas will execute them. Watch for the feds to call it terrorism, try to grab jurisdiction so they can spare their lives.
I sure hope Texas tells the Feds to back off... unfortunately TX has become rather a pushover of late.
(Remember the "border crisis" a while back? Or very recent the USSC decision that was essentially "we don't like you having any restrictions at all on abortion!"?)
Fox just reported that the last suspect killed himself.
That's assuming a police officer was not cross with them at the time of the arrest, and that a prosecuting attorney does not run afoul of the 39th penumbra of the nine emanation at some point during the case.
