A 21-year-old woman appeared in Old City Hall court Sunday morning charged with second-degree murder in the death of her boyfriend this weekend.

The man died after being found critically wounded Friday night in the underground parking garage of an apartment building near Avenue Road and Wilson Avenue.

One of the woman's neighbours in the building told CBC News the couple often argued.

"We believe the death stems from a domestic dispute," Det. Paul Warden of the Toronto police homicide squad said. "We do know some kind of altercation occurred."

Warden said police found blood in the woman's third-floor unit.

Paramedics called to the building on Ridley Boulevard found the man in the parkade, bleeding to death from trauma to his chest. He was later pronounced dead at the scene.

Police theorize that he was stabbed with a sharp weapon and then tried to get to his car to drive away to get help.

The man didn't live in the building, but residents said he was often there to see his girlfriend. They had known each other for about three years, Warden said.

Family member weeps in court

The victim has been identified as 28-year-old Jason Paglia. His family was at the Toronto coroner's office Sunday afternoon to help with the investigation. 

Police arrested Kaila Dupuis and laid the murder charge against her Saturday afternoon.

At court on Sunday, one of Dupuis's family members who was in attendance broke down in tears during the proceedings. Dupuis's eyes were red but she otherwise remained steadfast. 

She was remanded into custody and will appear in court later this week to sort out her legal representation and arrange a full bail hearing.

Neighbours said she has a young son who attends a local daycare.
