A Napier woman accused of deliberately causing a fatal crash was highly unlikely to be wearing a seatbelt, a serious crash investigator has told a jury.
Lyree Sayers, 26, is on trial for manslaughter in the High Court at Napier. She is accused of trying to commit suicide by smashing into Pam McGarva's car on July 9 last year.
Ms McGarva, a 55-year-old kindergarten teacher, suffered serious head injuries and died in hospital 10 days later.
Senior Constable Corey Ubels told the court Sayers' car crossed a wide medium strip between the two lanes, and crashed into the front-right side of the oncoming car.
He said his examinations showed none of the usual evidence that Sayers' seatbelt was worn at the time of the crash.
