The man accused of killing Dylan McGillis on Edmonton's Whyte Avenue in 2006 has been convicted of manslaughter.

About 35 friends and family members cried and broke into applause after Court of Queen's Bench Justice John Gill found Cliff Decoine-Zuniga guilty in Edmonton Court of Queen's Bench on Friday morning. 

"I'm happy, but bittersweet happiness," said McGillis' mother Marlene Beres. "It's a good day. It's a very good day."

Decoine-Zuniga, 26, was found guilty after the judge accepted statements that were secretly recorded by undercover police officers during a so-called "Mr. Big" sting. 

On the recordings, Decoine-Zuniga was heard admitting that he was on Whyte Avenue the night McGillis was killed and that he stomped and kicked the young man while his friend stabbed him. 

Justice Gill said the statements were "compelling and reliable" and had a "clear ring of truth."

Outside the courthouse, Grant McGillis reflected on how the crime will affect Dylan's daughter who was born after her father was killed.

"He'll never be able to see his daughter," McGillis said. "She'll never have her dad hold her." 

"Dylan's arms should be around his daughter," Beres said. "Not where he is."

Sentencing has been delayed until next week.
