Jacques Amakon of Oshawa, Ont., has been charged with the fatal stabbing of another teen found bleeding to death in a bus shelter on Tuesday afternoon.

Amakon made a brief court appearance Wednesday, charged with second-degree murder and possession of a dangerous weapon. The court ordered the 18-year-old remanded in custody.

Amakon and Mike McDonald, 16, also of Oshawa, allegedly became involved in a fight on Tuesday afternoon.

A crowd of students witnessed the altercation which took place outside the grounds of Monsignor Paul Dwyer Catholic Secondary School on Stevenson Road North in Oshawa, about 45 minutes east of Toronto.

Both teens were students at the school.

Police allege that Amakon drew a knife and fatally stabbed McDonald.

McDonald, known to his friends as "Biggie," fell to the ground.

"The accused walked away from the scene with the knife and was arrested … a short time after the incident," said a statement from Durham Regional Police

When Amakon was arrested, he no longer had the weapon, which police described as "a kitchen knife or steak knife with a black handle."

McDonald was a student at Monsignor Paul Dwyer and was waiting for a bus after school when the altercation took place.

'I saw everything'

McDonald was rushed to hospital, but died a short time later of his injuries.

According to police Amakon was "arrested within a few minutes of the incident, in the vicinity."

"I saw everything," Samantha Passero, a friend of McDonald's, told CBC News. "I saw the whole fight go down, and I saw my friend collapse in front of my eyes."

Other witnesses told CBC News that a student videotaped the incident and that police have already interviewed the student.

Erin McDonagh, another student, brought flowers to the bus shelter, which quickly became a makeshift memorial. She said it was common knowledge at school that the suspect carried a knife.

"Like, he never really like threatened anybody with it. I don't even know why he even had it. I just seen it, like, once or something," she said.

McDonagh said McDonald and the other male had a long-standing feud that started two years ago. Darlene Rich, spokeswoman for the Durham Catholic District School Board, said classes would go ahead Wednesday as scheduled.

"I don't think classes will be quite normal. I don't know what it takes before classes — or life — resume to normal for many involved," she said

Grief counsellors will be available for students and staff.
