A jail guard charged with murder, drugs, etc.   Very sad but somehow not surprising in light of the endless problems with our jails and prisons, especially with drugs and gangs.
It would be interesting to know at least the basic details of the temporary restraining order that was mentioned.  For instance, was the mother the one who sought the order?  Since the order was granted "several years ago," it might also be completely irrelevant to this tragedy, depending on the details.
