Was a left-handed putter used as a weapon?

Is this compelling evidence of a golf putter being used as the head wound weapon?
Judging by the outline of the wound, it almost looks as though it was a left-handed putter, as in the picture.

I wonder if anyone in the house was left-handed?

Used sideways? That could explain the lack of surface wound.
