The incident occurred on a Toronto Transit Commission (TTC) bus at Kipling Station just before 12:30 p.m. of June 17. Emergency crews arrived at the scene to find that a woman had been set on fire. The fire was extinguished, but the woman — identified by police Monday as 28-year-old Nyima Dolma of Toronto — suffered life-threatening injuries. Dolma was rushed to hospital, where she died of her injuries on 5 July. A suspect was arrested nearby after the incident and charged with a number of offences, including attempted murder. Police said Monday that their investigation revealed there was no connection between the young woman and her attacker. Police also announced the upgraded charge on Monday in the wake of Dolma’s death. Investigators said 33-year-old Tenzin Norbu of Toronto is now charged with first-degree murder in the case. He appeared in court via video link on Monday morning. Dolma’s family has previously said she “lived a life of service to others and cared for many people”. An online fundraiser has been set up to help cover health care and funeral expenses. The family has asked for privacy as they deal with Dolma’s death.
