The body of Johan Kiktorak was found in Inuvik, outside and frozen on Christmas Day.
The 50-year-old man was discovered by a person passing by, late in the afternoon, yesterday.
"He was staying with a friend, but had not been seen for four or five days," said his younger sister Veronica Kiktorak.
She described her brother as "loving and caring."
Inuvik RCMP confirm they are investigating the death in conjunction with the local Coroner and the Chief Medical Officer.
