A jury took just three hours to find former Dunedin doctor Venod Skantha guilty of murdering 16-year-old Amber-Rose Rush.
The teenager was found by her mother in her bed in a pool of blood on February the 3rd last year.
The jury returned a unanimous verdict, as well as finding him guilty of four counts of threatening to kill. .
Miss Rush's mother, Lisa, died of a suspected suicide in June last year, a few months after her daughter's murder.
During the trial the Crown called 69 witnesses and put more than 1000 pages of evidence before the jury.
RNZ Otago-Southland reporter Timothy Brown sat through much of the evidence and speaks to Susie Ferguson.
