Principal Crown advocate Philip Evans said the couple had been in a relationship for five years until it came to an end in October 2013. Osler had to move out of the family home to live with his sister and blamed Sutherland from the break-down in their relationship.

During the course of the first telephone conversation with a counsellor Osler admitted he had been following Sarah Sutherland with a view to finding out where she lived and who she was seeing.
'During the course of the police interview he said his ex-partner had a three-quarter litre bottle of vodka that was one quarter full. He said he had put 10ml of Mr Muscle bleach in her vodka. He said he did this to Sarah Sutherland as an act of revenge for the ending of the relationship when Osler went to her home for a children's party.
'Miss Sutherland recalls him pouring her vodka in a glass and he mixed it with Coca Cola. She said he then poured her a vodka and orange which she said tasted funny. She put that down to the cheap orange juice mixer. She said she recalled the peculiar taste. She recalled the next day she had a headache.
'By the Monday and Tuesday, because this happened on Saturday, she was experiencing diahorrea.'
