Police in Sault Ste. Marie have deemed the deaths of a wife and husband last month a murder-suicide.

The Sault Ste. Marie Police Service says officers responded to a call on May 1, and arrived to find a husband and wife dead.

Police say the wife was found inside a house while the husband was found dead in a vehicle outside the house.

They say an investigation has determined that the husband first killed the wife by strangulation, and then died by self-strangulation.

Police say the case of intimate partner violence is believed to be an isolated incident.

They are not identifying the victims.
