The family and friends of a slain Toronto teenager have released a series of new appeals to those responsible for his death, asking them to come forward and admit what they have done.

Eighteen-year-old Jarvis St. Remy was gunned down at a bus stop on the northeast corner of Dundas Street West and Howland Avenue on May 1.

He was on his way home from a friend's house when he was shot, only weeks before the aspiring engineer was scheduled to graduate from Western Technical-Commercial School.

St. Remy died hours later in hospital.

Investigators believe that at least two male suspects were involved in the teenager's murder, but the case has been tough to crack: St. Remy was not known to police and his family says he had no involvement with gangs.

Police say they cannot identify a motive for St. Remy's death, though they hope that witnesses will come forward to provide useful information in the case.

Since St. Remy died, his family members have made a series of public appeals for his killers to come forward to police.

On Friday afternoon, his mother and grandmother once again reminded the public that St. Remy left behind a family who loved him.

"I don't want Jarvis' case to go as another unsolved mystery ... I want justice for my son," Clemee Joseph said at an outdoor news conference near the bus stop where St. Remy was killed.

His grandmother, Dolores Watson, said the family is hoping that the killers will have some remorse when they see the pain they have caused St. Remy's surviving loved ones.

"They say time heals everything, but I don't think that time can heal that," said Watson, referring to her grandson's murder.

"I have his picture around with candles lit up, every day and every night. And I am hoping, I am really, really hoping that those killers come forward."

And on YouTube, the victim's brother, Kasim, has posted a similar appeal for the killers to give themselves up because Jarvis St. Remy "didn't deserve it."

Anyone with information is asked to call police at 416-808-7400, or to call Crime Stoppers at 416-22-8477. Members of the public can also send in tips online www.222tips.com, or by texting TOR to CRIMES (274637).
