Murder of the UnitedHealthcare CEO

Is there a source to the “terrible back pain” part?

If so, that still seems like a poor reason to kill a CEO of a health insurance company.

Seems like speculation about personal insurance denials, etc. Is there evidence?

If we’re just speculating, I heard rumor that perhaps he fell in with a “cult” while in Hawaii. If so perhaps that was what turned him into what he is.
