The reader has no knowledge of the person represented by the word "his". We do not know is it was "his own" head.0bdfbc
Point well taken! Should have had this one!
As the person is not mentioned and for suicide 'his' must be folllowed by 'own'. Better stick to murder
Neither He nor His has an antecedent so one must assume the He and His are the same person because a pronoun represents the noun immediately before it in the written discourse. But in oral conversation He and His could be different people. While the linguistic rules are broken common understanding depends on the context.
