The woman stabbed last week at a Shoppers Drug Mart in an underground pathway beneath Toronto's financial district has died.

Rohinie Bisesar, 40, was arrested Tuesday and charged with attempted murder, aggravated assault and carrying a concealed weapon after the attack at the drugstore located in the underground PATH system below Bay and Wellington streets.

Const. Victor Kwong says those charges will be upgraded.

Police believe Bisesar did not know the victim, who has not been identified.

The stabbing happened just after 3 p.m. The victim was rushed to hospital and later put on life-support.

Bisesar made a brief court appearance Wednesday morning.

Calvin Barry, her lawyer, told reporters "she seems really sad," but he wouldn't comment on other aspects of Bisesar's life.

Bisesar had graduated from York University's undergraduate and graduate business programs, and had several jobs in the financial district.

She will remain in custody, likely at a jail in the Milton, Ont., area, Barry said.

Bisesar is due back in court Friday, but Barry suggested it may be early January before she gets a bail hearing.
