The mother of the man who died of a gunshot wound in the drive-thru lane of a Burger King restaurant last week says there is no way her son shot himself.

Zoltan Hyacinth, 23, died on March 17 at the Burger King near the corner of Keele Street and Wilson Avenue.

The Special Investigations Unit (SIU) says police officers were attempting to make an arrest at about 9 p.m. when "there was an interaction between police and a man. A short time later, the man sustained a gunshot wound."

Hyacinth was pronounced dead at Sunnybrook Health Sciences Centre.

In a CBC News exclusive interview, his mother, Michelle Hyacinth, 44, told the CBC's Kimberly Gale she didn't know her son had been killed until she called the number on an SIU card left in her door two days after the incident.

According to his mother, Zoltan had recently gone back to school after dropping out and had planned to go to George Brown College to become a chef. He lived at home with his mother and  sister, 19, spending much of his time with his girlfriend Angelica.

Zoltan was known to police.

"He had a few run ins. It certainly wasn't an extensive history," said the family's lawyer Alonzo Abbey.

'Whatever the outcome, at least I'll get the truth in the end.'— Michelle Hyacinth, victim's mother

"We're hopeful that the SIU will produce some truthful facts and the family will take it from there."

Rumours circulating that Zoltan may have pulled out a gun and somehow shot himself are untrue, according to his mother who emphasized that he "loved life" and was very positive.

"I know that's a lie because I am one of those parents who goes and search to make sure there's nothing in there," she said. "I know for sure as a mother, I know there's no gun that's ever been in my house."

Two weeks ago after celebrating her son's 23rd birthday, Michelle Hyacinth is planning his funeral, set for Tuesday. Family and friends are flying in from Trinidad and Alabama for the event.

After she has put him to rest, Hyacinth said, she will focus on finding the truth about how her son died.

"In the end, I'll get justice for my son," she said. "Whatever the outcome, at least I'll get the truth in the end."
