Prosecutors are asking an Ontario judge to rule that a former pastor convicted in the death of his pregnant wife was the one who gave her a sedative before she drowned.

The Crown is making submissions on what the court should deem as a fact in sentencing Philip Grandine, who was found guilty of manslaughter in February in the death of his wife Anna Grandine.

Jurors were told they could convict Philip Grandine if they found he secretly drugged his wife with the anti-anxiety drug lorazepam or provided it to her; or he knew she had taken it and did nothing to stop her from getting in the bath while under its influence.

Now prosecutors say the judge should rule that Philip Grandine surreptitiously administered the medication better known as Ativan to his wife, having stolen it from his workplace with the intention of incapacitating her.

They are also asking the court to find that Anna Grandine, who went by Karissa, did not knowingly consume the drug.

Anna Grandine was 20 weeks pregnant when she died in October 2011, and tests later revealed she had lorazepam in her blood despite never being prescribed it.
