Police have identified the 45-year-old Vancouver woman attacked in a Gastown suite early Sunday.
Constable Tania Visintin says Tonya Hyer was still alive when paramedics reached her at about 1:30 a.m. but died before she could be rushed to hospital.
Investigators have not said what caused her death but Visintin says they believe someone has important information about her homicide -- the third in Vancouver this year.
No arrests have been made.
