The family of a teenager shot dead outside his home on Jamestown Crescent is issuing another plea to the public for help finding his killer.

Jarvis Montaque, 15, was shot and killed as he stood with a group of friends on Sunday, Feb. 17. He had moved to Toronto from Jamaica less than two years ago.

Tanasha Smith called on people in the community to come forward with any information about the death of her brother, who was the only male sibling in a family of 10 sisters.

"Jarvis was an amazing person," said Smith. "There are no words to explain how we feel right now."

Police also called on anyone with information about the case to come forward.

"We need witnesses," said Toronto police Det. Darlene Ross. "We need people who are willing to have the courage to step forward and provide information."

She also stressed that anyone with information can submit it to police anonymously by calling 416-222-8477 of visiting www.222-tips.com.

"Every single one of these methods … still allows you to be completely anonymous," said Ross.

The family will hold a memorial for Montaque on Thursday.

They are also collecting donations to help cover the cost of transferring his body back to Jamaica.
