True Crime Chatter

The cases of the Las Cruces Bowling massacre and the Austin Yoghurt Shop Murders both occured within about a year of each other, were violent far in excess of a normal robbery and remain unsolved. That said, I'm hopeful one or both can be cracked (even if it's a deathbed confession).

Any thoughts on whether these were accidental escalation of a robbery or were full intended chaos from the start? Do you think justice can be still served now?
