Crown Prosecutor Clayton Walker said to Sayers "don't you think that is astounding that in the context of this coroner's hearing, following on from a High Court trial where the accusation was you attempted to commit suicide in crashing the car, that you don't remember having suicide thoughts in the past?"
"You would remember those suicide thoughts, and you do remember them, don't you?" Mr Walker asked.
"I think I was just saying things to get attention," Sayers responded, because she wanted "love, like happiness and kindness from someone".
She told the hearing that she and her brother would joke about having a pact to commit suicide together.
"We would joke about different things. I would say . . . wouldn't it be funny if on their birthday we both committed suicide. Happy birthday."
She admitted it sounded horrible but the conversations were not serious.
Sayers said she was glad her brother was not there when she told the story as he would be laughing.
She also admitted to joking about committing suicide to a shop assistant at a hardware store.
She said she tried to amuse herself by telling the assistant she wanted a nail gun to put in her head.
Hawke's Bay Area Commander Inspector Tania Kura told the hearing she spoke to Sayers' father, Patrick Sayers, on the night of the crash when his daughter was in intensive care at Hawke's Bay Hospital.
Ms Kura said Mr Sayers told her he wouldn't be surprised if Lyree had intentionally tried to commit suicide by crashing.
She said it was a spontaneous comment from him, and not as the result of any questions that she asked him.
Ms Kura said Mr Sayers was making a lot of comments about Lyree struggling in the past with mental illness and drug use.
