Police have now released the name of the young woman stabbed to death at a Shoppers Drug Mart in the PATH system.
28-year-old Rosemarie Junor died in hospital after an attack last Friday in an unprovoked assault.
Initially, 40-year-old Rohinie Bisesar was arrested on charges of attempted murder, aggravated assault and carrying a concealed weapon.
The charges have now been upgraded to second degree murder.
The accused made a court appearance on Wednesday and was expected to be back in court Friday seeking bail, which is now not an option with Junor’s passing.
