One of the brothers charged in the death of a Mississauga teenager this week appeared in court briefly on Sunday.

Mark Mahabir, 20, turned himself in to police on Saturday evening. His brother, Nicholas Mahabir, also 20, was arrested Friday night. Both were charged with second-degree murder in the alleged slaying of 14-year-old Riley Driver-Martin.

Mark Mahabir was joined by his lawyer, David Midanik, in a Brampton court. Midanik told a justice that he needed more time for disclosure in order to set a date for a bail hearing.

The case was put over until Dec. 24.

Nicholas Mahabir made his own brief court appearance yesterday. His next hearing is scheduled for Dec. 21.

Police discovered Driver-Martin's body with "obvious signs of trauma" in a Mississauga Park on Friday morning. Const. Iryna Yashnyk, spokesperson for Peel Regional Police, declined to comment on the nature of his injuries and the ultimate cause of his death.

Yashnyk also would not answer questions about whether the victim and the two accused knew each other.

Driver-Martin left his home Thursday night, but was not reported missing to police before his body was found the following morning.

The park where he was discovered is not far from Clarkson Secondary School, where the victim attended classes. In a letter sent to Clarkson families, the school board said "police believe this is an isolated incident and have assured us there are no additional safety precautions needed at our school."

Nicholas Mahabir was arrested late Friday evening, while his brother turned himself in to police on Saturday hours after investigators issued a warrant for his arrest.

Both men were known to police, Peel police Const. Heather Cannon said Sunday.

She added that the area where Driver-Martin was found remains an active scene and a command post will stay in place until the end of the day. Officers are still canvassing the neighbourhood and are appealing to anyone with potentially useful information to contact police or leave an anonymous tip with Crime Stoppers.
