  • At least a half dozen suspected murder-suicides — or familicides — occurred in the US in December.
  • Perpetrators are typically middle-aged men; precipitating events are often separations or divorces.
  • Experts have flagged easy firearms access and a lack of violence-interruption programs as causes.

From Hawaii to New York, Arizona to Massachusetts, some involving children, others involving spouses or intimate partners, news of suspected murder-suicides gripped Americans throughout December.
