Jurors in the Jordan Manners murder trial will resume their work on Friday, after the jury failed to reach a consensus in the case on the third day of deliberations.
Justice Ian Nordheimer instructed the jury to take another day after he was informed that an impasse had developed on Thursday afternoon.
The jury has been deliberating since Tuesday in the case, which centres upon the 2007 shooting death of Manners.
Two men are facing first-degree murder charges in the death.
Both of the accused are now 20-years-old, but they cannot be named because they were youths at the time of Manner's death.
On Thursday, security was ramped up at the courthouse and members of the emergency task force were also on hand.
The increased police presence was partly attributed to the large number of people at the court awaiting the verdict.
On Wednesday night and Thursday morning, a large group of young men were spotted loitering out front of the Ontario Court of Justice, which is near Queen Street West and University Avenue.
The youths were wearing blue and white, which are colours linked to the Crips street gang.
"I would hope we wouldn't have problems," said Det. Sgt. Mike Barsky.
"The fact that we have ... the youths that are staying outside of the court concerns us, and because it concerns us, we have increased that presence in the hope that we will stop anything from happening before it does happen."
In a crime that shocked the city and made headlines across the country, Manners was gunned down at his school on May 23, 2007.
