The victim of a gruesome murder was not a violent man and garda sources say they do not know what he could have done, if anything, to have warranted being killed in such a brutal fashion.

Murder victim Francis 'Frankie' Dunne was a client of a high-support shelter a short distance from where his decapitated body was found.

Gardaí investigating the gruesome killing of another homeless man in Cork, whose head and arms were apparently cut off, have appealed for witnesses to contact them.
