I read this short story in the 1960s (in an anthology, probably an American hardback, no later than 1967) but it probably dates from the 1950s.
For reasons I can't recall a maniac gains control of a space ship's control room and kills the entire crew. The only deaths I can remember are two crewmen who try to gain access to the control room by climbing between the ship's double hull; the maniac finds a way to compress the two hulls, crushing them to death. After having killed everyone the maniac congratulates himself, unaware that the last of the ship's oxygen has just run out.
- I'm sure I read it in an anthology and not a magazine and it could not have been later than 1967.
- The killer was human and I believe the ship was a civilian vessel.
- I'm pretty sure it was an American hardback.
