It seems that's just a collection of any piece of violence committed by a pro-abortion "activist" or doctor. Like in the case of the satanist shooting "pro-life minister" Simon -- he was probably killed because he was a minister, not because he was a pro-life activist.
It seems that Janezic was a) insane (she's serving her life sentence in a mental institution) b) an avowed satanist. The idea that she was "a pro-abortion activist" (what's that supposed to be, exactly?) and/or (however locally) "well known" seems to have arisen on the internet about a decade after the act.
Worth noting she shot a preacher who certainly was locally well known and certainly was a pro-life activist. And that she did so at a time when the murder of an abortionist was getting a lot of media attention. For all I know, Janezic might have considered abortion to be murder, and approve of abortionists on these grounds.
