The 15-year-old who died after he was shot in a downtown Toronto apartment building was a "diamond in the rough," his high school football coach told reporters Monday.

At a news conference convened at the Central Technical School on Monday morning, football coach Norm Davis said he felt it important to let the community know exactly what kind of individual Tyson Bailey was.

"People need to know how good he was. He's like all of us, he's not perfect, but he was good and he had the potential to be great. And now, we don't know, because he's gone," Davis told reporters.

Apparently struggling to keep his own emotions at bay, Davis recounted an incident from the team's first game, during which Bailey was tackled from behind and reacted angrily.

A similar incident transpired in the second game, Davis continued, but he explained Bailey reacted very differently that time.

"He got up and he gave a little smile and he walked back to the line to do the play. You could really see there, he wasn't selfish at that point. He was keeping his emotions in check."

Bailey died Friday afternoon after he was shot inside a stairwell at an apartment building at 605 Whiteside Place, near Dundas and River Streets, just east of Toronto’s downtown core.

So far, no one has been charged in connection with his death.

Police believe Bailey may have been the target of someone "lying in wait" for him when he visited a 13th-floor suite in the Regent Park highrise, considering that they received a call about the fatal shooting just minutes after investigators believe Bailey arrived at the building’s front door.

"He entered the apartment very shortly before shots rang out. We’ve confirmed that with the video surveillance system," Det. Sgt. Justin Vander Heyden told CP24 on Sunday. "It looks like he attended the 13th floor with a person who’s associated with the apartment where we executed the search warrant."

Police also said Sunday that Bailey’s reason for visiting the apartment suite wasn’t clear, though they did confirm he was friends with the four men who lived there.

Anyone who saw Bailey prior to 2 p.m. Friday, or has any other information about the case, is asked to contact Det. Sgt. Vander Heyden at 416-808-5100. Anonymous tips can also left with the Crime Stoppers hotline at 1-888-222-TIPS or on the Crime Stoppers website.
