I must admit that I'm not that big a fan of the online version of the Toronto Star (hate registering with them), but you have to give them credit - they're the first large online Canadian news site to use a mashup with Google Maps. They've combined Google Maps with GTA homicide statistics to pinpoint locations within the GTA where people have died.
Check out the Toronto Star and Google Maps mashup here: Homicides in the GTA, 2005 to date
The site lists in chronological order each homicide (some with pictures of the victims) and their age and gender.
You can browse by Region: Toronto, Peel, York, Halton, Durham and read (with pictures) of the Shooting, Stabbing, Beating, etc. deaths of people in the GTA for 2005.
When you read the numbers - Toronto has had 60 homicides so far this year - that's pretty scary.
The Toronto Star has also provided a Google mashup of the key developments in the Alicia Ross case, with points linking to places where activity has taken. This is a pretty interesting application of an on-going investigation.
Now, when are the other news organizations (Globe and Mail, Canoe, National Post, etc.) going to follow suit?
