CALGARY — Cold case investigators working on a 2007 homicide file in Calgary were able to uncover new evidence, which led to the arrest of two men in Ottawa and Toronto last week.

Nader Nilianbousheri, 32, was shot and killed in his home in the 3900 block of 16th Street S.W. in November 2007. Police said at the time Nilianbousheri was the victim of a home invasion and was involved in a fight with the suspects, which resulted in his death.

On Oct. 8, police in Ottawa and Toronto arrested two men.

“Really it was great investigative work, great analytical work that brought the information that was there initially," said Homicide Staff Sgt. Colin Chisholm. 

"A second look at the investigation led to just a cascade of further information and further evidence that was able to lead us to the point where we were able to make arrests last week.”

Chisholm said the original investigators identified numerous suspects but those people had numerous aliases.

“The investigators followed the leads that they had,” said Chisholm.

Mahamed Mohamud Mussa, 42, of Ottawa, and Mohamed Yousuf Mohamed, 43, of Toronto, were arrested and each charged with one count of second-degree murder.

“Like all of our unsolved homicide cases, they always remain open,” said Chisholm.

“And our investigators, like they have in this case and several other cases over the last two or three years, have been able to bring new information together and lay charges. Obviously that’s our goal, to bring justice to the victims of homicide and their families.”

Police have been in contact with Nilianbousheri’s family through an intermediary, said Chisholm.

Both suspects have been transported back to Calgary and appeared in court Wednesday morning. The next court appearance for both is set for Oct. 22.
