A 41-year-old man has been charged with first-degree murder in the death of an 82-year-old French tourist in Quebec City.

Sylvain Fournier, of Quebec City, is also charged with attempted murder and two counts of uttering death threats.

The elderly tourist and his 76-year-old wife were found by police inside a unit of an apartment building on Rue Colbert.

Quebec City police spokesperson Pierre Poirier told CTVNews.ca that officers received a call about a stabbing Sunday night around 8 p.m.

Both were brought to hospital, where the man was declared dead. His wife was treated by doctors and is now in stable condition, Poirier said.

The couple knew the family that lived inside the apartment unit, but Poirier would not comment on the nature of their relationship.

Police arrested a suspect at the building Sunday night.

Fourier is expected to undergo a psychological evaluation to determine whether he is fit to stand trial.
