Looking for special picture

Hello,

When I was about 7-11 years old, I saw a picture on the TV. It made a deep almost traumatic impression on me.

As I recall: It was a Vietnamese police officier standing on the right, shooting a vietcon who was kneeling and I thought a third person on the left. The officiers wife and children had just been killed by the vietcon

I am looking for the picture, or photographer or anyone who can help me in finding that particular picture.

I want to use it for a painting. I am making a serie on war. The attack on the USA in september, triggered the idea.

Please e-mail me if you can help me.

With kind regards, Lucas Barenbrug Amsterdam The Netherlands
