It was a Delta Airlines flight. Delta confirmed the copilot no longer works for them

I wonder if the flight diverted or if it continued? I think the gun would override the medical condition.
With the guy on the flight deck jump seat who tried to shut down both engines last week, this incident and the pilot who who took an axe to the barrier in a car park a few months ago when he could not get out of the car park, mental stress on pilots needs to be taken seriously.
