Michael John Anderson (born October 16, 1988, in Savage, Minnesota) was convicted of having murdered Katherine Ann Olson in October 2007. Because Anderson met Olson through Craigslist, a popular classified advertising website, the media dubbed him a Craigslist Killer, a generic term for murderers who find victims by placing or responding to ads on Craigslist. Anderson was the first killer given this title in news accounts.
