This is very strange. Below is a link to a page on the crash in France on 14 June. Note: Howard is captured, only one man evaded. Why would his name show up again on a dogtag at Bleckmar on the 20th?
Note: the translated German document on Howard (posted above) says the plane was from the 96th Group 337th Squadron. Howard was in the 457th BG, 750th BS.
Note the date of the Bleckmar crash should be 20 June (not 30 June) as I first posted, sorry. I corrected my original post, but I note it is wrong in the "quote".
