Toronto police are looking for a male suspect in connection with the fatal shooting of a 15-year-old boy from the city’s Jamestown neighbourhood.

Officers say the suspect was wearing all black when he walked up to victim Jarvis Montaque and shot him at closer range outside his west-end Toronto home Sunday night.

Montaque is the fifth male youth under the age of 20 who has been killed by gunfire in the Greater Toronto Area.

The teen was shot on Jamestown Crescent, near John Garland Boulevard and Kipling Avenue, shortly before 11 p.m. on Sunday. He later died in hospital.

On Monday, those who knew Montaque described him as a hard worker who volunteered in the community.

“We’re in shock because there’s no known enemies…there’s no trail here,” Pastor Al Bowen told CTV Toronto.

Bowen said he knew Montaque from church. “He was quiet, (had) a great attitude, sense of humour, always smiling.”

Det. Joyce Shertzer said the Grade 10 student was not known to police, lived with his family in the Jamestown Crescent community and he did not have many friends outside of his extended family.

“There was no exchange, there was no verbal exchange. It was just as though (the suspect) approached and shot,” Shertzer told reporters outside the homicide scene on Monday.

“Gun violence sucks, and I’m not trying to make light of it at all,” she continued. “It’s an issue that we’re trying to contend with.”

She said police are asking for witnesses to contact police.

“We're hopeful, because it was a long weekend and today is Family Day, that people may have been up later than they normally would have been instead of retiring early to go to bed or school -- that people would be up and have seen something," she said.

Violent start to 2013

Montaque’s death marked the fifth death of a young man resulting from gun violence in the GTA since the beginning of the year.

Last Monday, 15-year-old St. Aubyn Rodney died after he was shot in the stomach at an apartment building on Turf Grassway, near Jane Street and Finch Avenue West. Police later charged a 17-year-old male with manslaughter.

On Feb. 10, 19-year-old Naveed Shahnawaz was shot during a fight in a parking lot on the CNE grounds. He died in a Toronto hospital early Friday morning.

Late last month nine-year-old Kesean Williams was shot and killed while watching TV in his Brampton home. The family had moved into the townhouse a week earlier and police said the shooting may have been linked to the previous occupants of the home.

In mid-January, 15-year-old Tyson Bailey was killed in a shooting at an apartment block on Whiteside Place, near River and Dundas streets.

Also on Sunday, a 17-year-old boy was shot in the city’s west end in a separate incident. He is recovering in hospital.
