Heavy rains may have hampered trick-or-treating for many, but the inclement weather did little to deter the disturbing violence that continues to plague the Greater Toronto Area.

Police and paramedics had a busy night with a rash of stabbings and shootings that left one person dead and at least eight others injured at various crime scenes across the region.

The violence began around 9 p.m. Thursday when two teenage boys were shot in East York. Police say they responded to reports of multiple gunshots fired at the rear of an apartment building on Cosburn Avenue just east of Pape Avenue.

Upon arrival officers found two victims, aged 15 and 16, suffering from gunshot wounds to the torso. Both suffered serious injuries but are expected to survive. Police said one male suspect was seen fleeing on foot and may have escaped running through backyards in the area.

3 stabbed at Annex frat party

Shortly after midnight on Friday police responded to reports of a large fight at what they described on Twitter as a “rowdy party” at a frat house in the Annex.

Once on scene at the house on Madison Avenue near Bloor Street West, police located five injured people — with three suffering from stab wounds.

The stabbing victims are all men between the ages of 18 and 25. One of them remains in life-threatening condition.

Police later arrested a 19-year-old man and a 15-year-old girl. They are expected to be jointly charged with three counts of aggravated assault, three counts of assault with a weapon, one count of attempted murder and weapons dangerous.

The male suspect also reportedly slashed himself, causing minor injuries.
