A makeshift memorial continues to grow outside the family home of Andrew Naidoo, not far from where the 15-year-old boy was shot dead earlier this week.

Bouquets of flowers, photographs and teddy bears were lined the fence – all things members of the Finch Avenue community hope might bring peace to the grieving family inside.

Tied nearby is a blue bandana and deflated blue balloons – the colour of the Crips, a local gang.

But Naidoo's family says he had no connection to street life, describing him as a caring son and brother who wanted to grow up to be a mechanic like his father.

"He was such a loving child. He wasn't doing anything bad. That's why I don't understand how this could happen to him," the slain teen's sister Susie Persaud told CTV Toronto's Tamara Cherry in an exclusive interview.

"He was an amazing child. He was loving, caring. He did anything for anyone. Everyone loved him and he's going to be truly missed."

Andrew Naidoo died early Monday morning after being shot multiple times near Martin Grove Road and Finch Avenue West Sunday night.

At 15 years old, Naidoo is the youngest of the city's 23 murder victims this year. His grieving family members are struggling to make sense of the sudden loss.

Persaud said Naidoo had gone to bed for the night, when she called to make plans to take him to school the next day. Their mother poked her head into his bedroom to tell him the news, but he was gone.

Naidoo's mother and brother, Brian, rushed outside and found him two townhouses away, riddled with bullets. They held him as they waited for an ambulance to arrive.

"My mom was saying, 'Just breathe baby, just breathe Andrew, just breath,' and Brian as well was telling him, 'Andrew just breathe,'" Persaud said.

A fatal heart attack claimed the life of Naidoo's father two years ago, leaving the 15-year-old to help his mother with chores around the house.

He grew up with Alyssa Persaud, his 11-year-old niece, looking over her like a baby sister, and was working his way into his father's trade.

Naidoo wanted to be a mechanic. Even at 15 years old he loved cars and dreamed of opening his own shop.

"My dad was a mechanic, so he wanted to follow in his footsteps," said Persaud.

"He was so close to my dad and when my dad passed away he felt it hard as well."

Members of the community say there is a deadly game being playing in the neighbourhood, where older gangsters will use kids as pawns.

Trisha Dukhcharran, a friend of the Naidoo family, said the teen was a good child, but questioned the effect the neighbourhood had on his generation.

"I don't know what brought him (out of bed), the reason, the whole reason, but the Andrew that I know, he's a very good loving kid," Dukhcharran said.

Toronto police say that while the investigation continues, no arrests have yet been made. Authorities say they believe Naidoo may have been with someone when he was shot, and that person could also be hurt.
