Gaston N. Riggs Crash at Heston February 26th 1945.

can anyone help regarding the crash of Mustang of 1st Lt. Gaston N. Riggs of the 503rd FS on February 26th 1945. Aircraft serial number was 43-6785 and was a P-51B.

The aircraft crashed into Grange Farm on the approach to Heston, and an account and some picture can be seen here: http://www.collectair.com/woodason.html

Interestingly I have found two different accounts of the crash

here http://forum.armyairforces.com/tm.aspx?m=137761

and here http://www.legionmagazine.com/en/index.php/2002/09/the-airman-from-the-crash/

I am trying to find out:

Where Gaston Riggs was based, and where his fatal flight began

A picture of him/ and or the aircraft

Where he is buried.

Any other clues or input appreciated!

Thanks
