I knew I had heard this happening before.

Delta Pilot gets locked out of cockpit on way to Las Vegas

What about Ethiopian Airlines Flight 702 last year?

One pilot locked the other pilot out and flew to Switzerland because he wanted asylum. Remembering this and reading about this latest incident says terrorism and/or suicide to me.

Hopefully we will get more info as time goes on.
