is the Writer’s Forensic Blog by D.P. Lyle, MD. I came across it after reading one of his books last year, called “Murder and Mayhem.” It didn’t have exactly the information I was looking for at the time, but I really like how he explains forensics with the writer in mind.
Oh, and he does highlight interesting “real world” cases on his blog, too. So it can be a great idea generator as well as a source for information.
