I am new here. I love the site crime library. It's an encyclopedia. I have created a blog about crimes. It's a blog in french:
http://lemagazineducrime.blogspot.com/ and the first articles are about Peter Sutcliffe, the "Yorkshire Ripper". It's a serial killer who killed thirteen women in the north of England in 70's. It's a an another ripper for England. Peter Sutcliffe is less known than "Jack the Ripper" but he had traumatized England as much has the latter. He knocked out women with a hammer and after that he lacereted their bodies with a knife. He was arrested in 1981 after too long investgations.
