Samson Wong wept Saturday as he apologized to his teenage son, saying he wishes he could have protected the young man from the stray bullet that took his life.

Alfred Wong was heading home to Coquitlam with his parents on Jan. 13 when a bullet pierced their vehicle on a Vancouver street, striking the 15-year-old. He died in hospital two days later.

Vancouver police have said they believe the shooting was gang-related.

"Alfred, forgive Mom and Dad. We failed to protect you," Samson Wong said at his son's memorial service on Saturday. "Mom and Dad have been talking. We wish the bullet went for our heart, not yours."

Sobs could be heard throughout the Coquitlam Alliance Church as Wong spoke to the crowd of about 700 mourners, saying he still can't accept or believe what has happened.

"Every morning when we wake up, we tell ourselves it was a dream, a bad dream," he said.

His son's body lay a short distance away, dressed in a red plaid shirt and grey toque, in an open casket.

In a eulogy he wrote but did not deliver himself, Wilfred Wong told the crowd that his younger brother was his "closest companion and an irreplaceable pillar" in his life.

"Fifteen years was far too short a time on Earth," Wong said. "But for 15 years, he lived a life full of happiness and joy. Thank you, Alfred, for being in our lives, reminding us to always be true to who we are and to always cherish the people we love and care about."

He said the teen had plans of becoming an engineer and filled his spare time with many extracurricular activities, including swimming, taekwondo, video games and basketball.

Alfred Wong's basketball teammates sat in a pew together, dressed in their black uniforms.

His long-time basketball coach, Steve Ashley, told the crowd that Wong was a true sportsman who found freedom in the game.

As the only left-handed player on the team, he had to work twice as hard to master drills meant for right-handed players, Ashley said.

He added that after Wong's death, the team played a game using only their left hands to honour their friend.

"It wasn't pretty," he said.

Pastor Caleb Choi of the Coquitlam Christ Church of China, where the Wong family are congregants, urged the crowd to hold Alfred in their hearts and honour him by living positive lives.

"Drowning in our grief is not enough. We must continue to live on," he said.

Performing a funeral for a 15-year-old is completely different from other memorials, Choi said outside of the service.

"We have no words to comfort the family, no matter what we say," he added. "What we can do is just pray for them."

Choi noted that Wong's family has set up two scholarships in the teen's name -- one at Coquitlam’s School District 43, and the other at the Hyack Swim Club, where Wong was was a member.

The scholarships are an attempt, Choi said, at making sure others get to live out Alfred's dreams.

"The family is very strong,” he said. “Even in the saddest time, they still have a positive mentality. That's very amazing."

“When they see people get help, get benefits from this scholarship, I think they will remember Alfred,” Choi said. “Also all the community people will remember Alfred as well in this positive way.”

Several officers from the Vancouver Police Department - including Deputy Chief Howard Chow - attended the service.

“His death has really rippled throughout the department,” Chow said. “It’s something that really was heartbreaking for everybody, including our police officers that attended (the scene) and are currently working on this file.”

Chow said the VPD is committed to doing everything it can to identify the person responsible for Wong’s death.
