The Craigslist Rapist : Guest Blog by Trench Reynolds:
This is a piece I did for the Investigation Discovery blog The Criminal Report Daily that’s run by David Lohr. It focuses on the craigslist rapist Mark Antonio Humphries.
UPDATE 12/21/2015: My piece was pulled from ID some years ago in what I’m sure was a housekeeping move however thanks to Archive.org I can bring it to you now.

I’m sure most of you are familiar with the Website Craigslist. In case you’re not, it’s a massive online classifieds site that has regional sites in most of the United States and major cities around the world. It was started in 1995, in San Francisco, California, by Craig Newmark and was originally intended as a personal site for him and his friends to communicate. Over a decade later, it’s a multi-million dollar business.
You can get just about anything you want on Craigslist – furniture, jobs, dates, even concert tickets; however, Mark Antonio Humphries was looking for something a little different on Craigslist – Humphries was looking for victims.
Before we get to Humphries, let me tell you about the other things you can get on Craigslist.
Craigslist has a section called “erotic services”. This is where the ads for “escort services” and “massages” reside. In other words, it’s where Craigslist allows anyone to post ads for prostitution.
Humphries, of Prince Georges County, Maryland, picked his victims from the erotic services section. Humphries was otherwise known as the “Craigslist Rapist”. From October 2007 through July 2008 Humphries raped nine women that he met through Craigslist. The women were either escorts or were looking for one night stands. Humphries would set up the meetings at empty apartments or motel rooms.
Humphries slipped through the grasp of police more than once and at one point he even went to the police himself, to fish for information.
On July 23, police finally caught up with Humphries at an apartment in Hyattsville, Maryland. After police evacuated the building, Humphries shot himself in the head. He died later that night.
Humphries may go down in infamy as “the” Craigslist rapist since he struck in an area near media-centric Washington, D.C.; however, he is not the only one.
In DeKalb County, Georgia, 18-year-old Allen Jamar McDowell was arrested for the rape of two women he met through Craigslist. McDowell is also HIV positive.
In Tigard, Oregon, 52-year-old Ronald M. Leistiko was arrested for luring several women to his home through Craigslist and raping them.
In California, 24-year-old Waymon Livingston was arrested for raping a masseuse he contacted through Craigslist. The DNA from the rape linked him to a murder for which he is now facing life without parole.
Rape is not the only crime being committed through Craigslist. 19-year-old college student Donna Jou disappeared after leaving on a date with a man she met on Craigslist and 22-year-old nanny Katherine Ann Olson was killed after answering an employment ad. Her killer took out the ad allegedly just so he could kill someone.
Craigslist is also a hive for various scammers, fences, and thieves. Not that these crimes haven’t been occurring since the dawn of the Internet, but I’ve never heard of so much crime being connected to one Website.
