I would start with the medications. They are pumping many people with anti-psychotics and some just don't do well. Especially when they stop them. The research that proves this is out there but is being scrubbed.
Way too much money involved. Think about when a doctor prescribes those types of medicine. They are generally for life. That's REPEAT business for big Pharma. That's not to say they don't help many though.
Just sayin. We never do hear what meds these shooters are on. School shootings or a tragic family shooting like this and it's just not discussed. Meds are THE COMMON denominator among mass shooters. It's almost like no one wants to get to the bottom of things.
How does one measure how many family massacres have been prevented by their use though? Easy to prove how many have died as a result if the data is released, not so with the lives saved.
