Alex Devlin was killed from shrapnel wounds to her back caused by a bicycle bomb (a bomb hidden inside a bicycle basket) outside of a Saigon restaurant as she waiting to meet Myron.
It was a general act of terrorism by the VC and she was just in the wrong place at the wrong time.
It was not related to her interview with the NVA general in the tunnels outside Saigon.
I hope that helps you.
