The jury in the Jordan Manners murder trial in Toronto will resume deliberations on Friday, after telling the judge they were at an impasse.

Jurors told the judge Thursday afternoon they were unable to reach a decision. Justice Ian Nordheimer sent them home for the night with instructions to resume deliberations on Friday morning.

Police stepped up security outside the courthouse Thursday due to worries about a group of people standing outside wearing gang colours.

The jury has been trying to reach a verdict since Tuesday afternoon in the case against two 20-year-old men charged with first-degree murder.

The men are accused in the death of 15-year-old Manners, who was shot to death in C.W. Jeffreys Collegiate on May 23, 2007.

The accused cannot be identified because they were minors at the time they were charged.
