Toronto police have identified the 10-year-old girl killed in the shooting rampage over the weekend as Julianna Kozis.

In a news release, police say the girl from Markham was killed when gunfire erupted in the city's Greektown on Sunday night.

They say the girl's family is requesting privacy during their time of grief.

Police previously identified the other person killed in the shooting as 18-year-old Reese Fallon.

Fallon had recently graduated from a local high school and was preparing to study nursing at Hamilton's McMaster University in the fall.

Thirteen others were injured in the attack and the gunman, identified as 29-year-old Faisal Hussain, was found dead nearby.

Hussain's family issued a statement on Monday saying their son had a long history of psychosis and depression and had not responded to numerous treatment approaches, including therapy and medication.
