Question about headline "Inmate Dies Anyway"

I came across this headline: "Oklahoma Stops Botched Execution. Inmate Dies Anyway." (link)

I was truly disturbed by the use of "anyway". To me, it implies a nonchalant attitude about something that is highly sensitive and controversial. Am I wrong? Is the use of "anyway" acceptable?

Update:

What made me post this question is the use of "anyway" in casual speech. For example, after a pause, one side says "Anyway, should we go to lunch?" So, I have this feeling about "anyway" being a less-than-worthy word that one would not use in formal settings. Am I still wrong?

Anyway can mean 'nonetheless', or it can mean 'whatever'. You are hearing the usage like 'Whatever... let's move on', when the author meant 'Nonetheless... inspite of our efforts'

I don't see much nonchalance in this case.

Anyway just means that something happens, notwithstanding actions that were expected to prevent it from happening.

His father forbade him to do that, but he did it anyway.
The road was almost impossible to drive on, but we tried it anyway.
Because of the storm, we attached extra lines, but the tent flew away anyway.
