Minimum of poetic license ? you too have a good imagination, Zantzinger ' tapped ' her on the shoulder with a toy cane, her death was caused by an undiagnosed heart condition, not like Bob said,

William Zanzinger killed poor Hattie Carroll,
With a cane that he twirled round his diamond ringed finger.

You don't kill someone buy tapping them on the shoulder.
You should research the old thread about Billy Zantzinger, all the truth is there if you look.
