His is possessive. One only has one head, one's own. Of course it's suicide.
RonBee
Alexander is right.
Chunky
It could be either though. Depends on the context :s
Jack
It's murder to me.
Jotter Scalems
But what if the shot isn't lethal? ;-)
Jenny
If it was 'her' head it would be murder but this could be either
Vidableek
Since this is using pronouns which are very indirect, it could be either. But what I first think of when I read the sentence is suicide.
Connan
There are no antecedents given for the two pronouns, so there is no way of knowing if "he" and "his" refers to the same person. Since this is unknown, suicide could be an incorrect answer if the pronouns refer to two different people. Murder is correct in either case because suicide is just a specific form of murder.
Helmaron
This sentence is a bit ambiguous as there could be two people involved in the situation. He, the murderer, put a bullet through his, the victems, head. I chose the suicide option because it was the most appropriate one with the information given
Janefroy
We don't have enough information to know for sure, but as written it sggests suicide.

Silvia Plath
Wouldn't suicide be 'he put a bullet through his own head'?
