Actually, he may be in Purgatory or he may be in Heaven. God judges us each uniquely. Some souls are in Purgatory for a very short time and then brought to Heaven. Some souls will be in Purgatory expiating their sins until the end of time.
Given that this good and heroic man showed the greatest form of love by risking his life for others, and then suffered terribly at the end of his life. I’d put my money on the fact that he’s probably in Heaven by now.
There are lots of souls in Heaven who have not been officially canonized as saints. They are all saints. The canonized ones are just the ones we are sure are in Heaven.
