Murray Olds: Australian correspondent on the daughter-in-law of the deadly mushroom victims being under investigation - Heather du Plessis-Allan Drive

A Victorian woman who cooked up a mushroom lunch which killed three and put another in hospital says she meant no harm.

The woman, a daughter-in-law of some of the victims, is being investigated.

Australian correspondent Murray Olds says police are baffled by this case, as no-one can identify what type of mushrooms were cooked and served to the victims.
