At Psychology Today Blogs, Katherine Ramsland tries to find some explanations for the spate of mass shootings ending in the suicide of the shooter. The article does not purport to explain why they happen, but does find similarities among them that seldom get noted in the news coverage.
A nugget (emphasis in the original):
We often don’t think much about the suicide angle in the aftermath of mass shootings, but a high percentage of these offenders had been depressed, angry, unstable, and unhappy with their lives. Yet instead of just taking themselves out, they decide to take others with them. What used to be an inward act has increasingly become outward.
I call this coercive suicide. We don’t yet know Aguilar’s motive, but typically suicidal mass murderers have the added need to punish someone, to make a public show of their death as a “lesson,” and/or to add their own notch on the infamy scale.
