Another said: "Dead man walking, you don't f*** with the 88s or any gang".
Mr Morris was known to have affiliations with the Head Hunters, and his tangi was held at the Fight Club 88 boxing gym in Ellerslie, which has strong links to the gang.
Since Mr Morris' death, members of his family have fought for the alleged killer's name to be revealed.
An online petition asking for support in naming Murray received 15,000 signatures, including Mr Morris' father Chris, who stormed out of court when the defendant was originally granted suppression earlier this month.
When contacted today police said as the matter was still before the courts they were unable to make any comment in relation to the threatening comments.
Murray's defence lawyer Marie Dhyrberg QC also said she was unable to comment.
However, a legal expert said there were no laws in place that prevent people from making these types of comments.
"There is nothing in particular the law can do, other than if these death threats appear to be real then a complaint can be made to the police," Professor Ursula Cheer from the University of Canterbury said.
Dr Cheer said if the threats appeared to be real in police could contact the service provider, which in this case would be Facebook, and ask for the comments to removed.
"The implication behind that is if they [Facebook] don't remove them, it could be seen as a criminal offence to be carrying messages of that kind.
"That's why the service providers usually take them down, Facebook are normally pretty good with that stuff."
