Cause of P-51 a F6 to crash 27September 1944

[Tom Kinnard]

Lt. James Warenskjold 0669936, a pilot of the 15th Tactical Reconnaissance Squadron of the 10th Reconnaissance Group was flying his P51 on a mission near Metz, France, on 27 September 1944 and never returned. His a/c # was 42-103427 (MACR 9226) and was named "Chumps Chance".
Approximately 7 1/2 years later his Mother was advised that his body was found under the plane in a heavily wooded area about 20 miles East of Metz. Identification was established by the contents of a bill-fold, a part of a dog-tag, and an expert's study of bones recovered. It was also mentioned that the engine had been "salvaged".
The family has never been given any information about the cause of the plane to go down or any other rated info. Do know that his wingman had to return to base because he was having instrument problems.
I checked with the Air Force about MACR 9225 and was given very little info, most of it unreadable because of it being in poor condition.
If anyone has any info on this it would be most appreciated.
