The life story for Commisso is finally up. Here's the link:
http://demarcofuneralhomes.com/book-of-memories/3546352/Commisso-Cosimo/obituary.phpHis father is Claudio Commisso, brother to Raymond. These brothers, along with their siblings, are first cousins to the more well-known Commisso brothers.
Edit: One of the more important pieces of information from the obituary is that Chantelle Almeida was
not the girlfriend of the murdered Commisso.
