No she didn't know her, that is why she didn't recognize her name and make the connection, until someone told her, she said that she knew the barrister Sandy Dawson, because she had "done some work for channel 7".
""The 38-year-old mother of three children was a lawyer and the younger sister of barrister Sandy Dawson, who has worked with Channel 7.""
Sorry, I stand corrected. I’m the one who needs to put his listening ears on. The reporter did say “Sandy Dawson, who I know...” and I thought she was discussing the deceased (who was actually Sandy’s younger sister).
