The incident occurred after Kemp and a friend had been drinking and were subsequently removed from a bar. They rented an e-scooter later that evening, and at speeds between 20 to 25 km/h (12 to 15 mph), Kemp collided with Phan, who was waiting to cross the road. Tragically, Phan sustained fatal injuries, passing away in the hospital two days following the accident. Additionally, Kemp's passenger suffered serious injuries, including a fractured skull, though they were not life-threatening.

In a Perth Magistrates Court hearing, Kemp appeared via video link and pleaded guilty to the charge of dangerous driving causing death while intoxicated, which carries a potential maximum sentence of 20 years in prison. Prosecutors had also initially charged her with causing bodily harm to her passenger but dropped that charge. Her blood alcohol content was recorded at 0.158 post-crash, significantly above the Australian legal limit of 0.05.

The court revealed CCTV footage depicting Kemp's dangerous riding behavior at the time of the incident. Phan’s family has expressed the deep impact of their loss, describing him as a cherished husband, father, brother, and friend. Julia Tudori, Kemp’s lawyer, indicated that she was feeling relief after her plea and expressed hope for a prompt sentencing, potentially before Christmas. Kemp, currently in custody and on a working holiday visa, will continue to await her fate in the justice system.
