Sounds like gross negligence, not murder 2.
And I don’t believe either of the 3 will be convicted of criminal charges.
But I DO believe this state senator holds a lot of influence over the DA that convened the grand jury and selectively fed them evidence and points of law.
Because only by that method would a grand jury indict on these trumped up charges.
Murder 2 *is* homicide due to willful negligence.
