Police investigating dead woman

The decomposing body of an old woman was found by a janitor in a Côte-des-Neiges apartment Sunday, and the tenant – a man of 45 – was arrested. No indication yet whether this was homicide.

Update: The man found on the premises is the woman’s son and he’s being evaluated: this item says there’s no evidence of criminal activity.

Further update: if the man is simple-minded as described here, why would he be charged with interfering with a dead body if the truth is that his mother died and he simply had no idea what to do?
