Progress is being made in the investigation of the Boxing Day shooting on Toronto's Yonge Street that injured six people and claimed the life of a teenaged girl, police said Wednesday.

"On Dec. 26, 2005 at approximately 5:19 p.m. Jane Glenn Creba … was in the area of Yonge Street and Elm Street when she was tragically killed," Det. Sgt. Savas Kyriacou said at a press conference.

Police kept the announcement short, confirming only a few details about the 15-year-old victim.

"Jane was a grade 10 student at Riverdale Collegiate," Kyriacou said.

"A post-mortem examination was conducted -- cause of death was determined to be a bullet wound to the body."

However, initial reports said Creba was the victim of a bullet that struck her in the head.

Kyriacou would not confirm the reports, except to say the cause of death was a gunshot wound.

"From an investigator's standpoint, we have to be so careful as to what we provide as far as the cause, Kyriacou told CTV.ca Wednesday evening.

"The investigation is on-going, and you have to understand we can not compromise the integrity of that investigation by releasing any more specific information than that."

He said that investigators want to prevent problems with future witnesses.

Police spokesperson Cst. Isabelle Cotton told CTV.ca earlier on Wednesday that the investigation is making progress.

"It's a very complicated investigation … We are going in the right path, but we need to do more interviews and things like that," Cotton said.

Dozens of evidence markers were visible at the scene Tuesday as investigators undertook the painstaking process of reconstructing what happened as the bullets flew.

Police also started a battery of forensic, ballistic and DNA tests on clues found at the scene.

"Any kind of test that we can do, we'll make sure that we do everything," Cotton said.

Two people were arrested shortly after the shooting, but no charges have been laid. Officers are looking for as many as 15 people believed to be involved.

Fantino not surprised

Meanwhile, Toronto's former police chief says he's not surprised to see the rash of gun violence on the city's streets.

"I policed in the city for most of my professional career and I know the city inside and out and, like I say, this is not a surprise," Julian Fantino, who is currently Ontario's commissioner of emergency management, told CTV's Canada AM.

"It's devastating to all of us to see this happen, but I suppose at one point in time we can all say that we saw it coming."

Fantino believes the problem is rooted in youth who don't perceive the criminal justice system to be a threat.

"Certainly we have to look at all of these socio-economic issues and considerations but at the end of the day, we're still dealing with a hard-core (group) of young people who are pre-disposed to violence, afraid of nothing and accountable to no one."

Mayor returning home

Toronto Mayor David Miller received news of the shooting while on vacation in Spain. He has cut the trip short to return to the city and contact the grieving family.

Miller said, as the father of a 10-year-old girl, he recognizes that Torontonians are reeling from the brazen shooting. He said the only way to reclaim the streets is to "make sure the streets are ours."

"We all have to be out on the street demonstrating that we're not going to be afraid," Miller told CTV's Canada AM on Wednesday in a telephone interview from Marbella, Spain.

The mayor says Toronto needs to work with the police force.

"We have to build on what the police are doing now, which is return police officers to the streets in all of the neighbourhoods of Toronto. That's critical," he said.

"The chief is redeploying police officers and we're hiring more so that we'll be able to be in the community all the time. Not just when there are problems," he said.

He said another immediate concern was getting the guns off the streets in a city that is already struggling with a peak in gun murders.

"Guns come from two places, about half of them come from the United States and about half are stolen from legal gun owners in and around Toronto which is why I support a ban on handgun ownership," Miller said.

The shootings made headlines around the world on Tuesday as CNN, NBC and the BBC broadcast the story.

While Miller says he recognizes Toronto's reputation is at stake, he says his immediate concern is getting the guns off the streets, and "if we do that, our reputation will take care of itself."

"The most important way we can deal with that is to arrest the criminals responsible and put them in jail so we send a strong message. If you have a gun and use it, you're going to jail."
