I think you are looking for B-24H-25-DT 42-51111 lost on April 24, 1944 in NH.
There's no mention of it on Baugher's site, but on accident-report.com as you said lists the date as April 24.
All I could find was this:

Sgt Lloyd E Utley is shown as being killed on April 24, 1944 in B-24H 42-51111, with no other details, so I'm guessing this is the one.
Other than that, I couldn't find anything.
Hope this helps.
edit: 2nd Lt. Marvin Rupp is shown as being killed on the same date in 42-51111, so..... problem solved. Now on to finding the details.
