I have a question..

Working on Harvard losses in India, i have come across the loss of FE601 of 320MU at Drigh Road - resulting in the deaths of:

Flying Officer John Steele HIGGINS (139032) 1943-04-03 616 Sqdn Pakistan Karachi War Cemetery
Leading Aircraftman Albert Edward LINTON (1222596) 1943-04-03 Pakistan Karachi War Cemetery

Both the names are not presented at start of this thread - does it mean they were "Accounted For"? If so - Where?
(trying to find out if there is a database somewhere in an alternate universe)...
