Murder is an awful, gut-wrenching thing. Most murderers hide their crimes, and try to cover up what they've done. Others are distraught and confess their actions. Then there are the outliers – the ones who gloat about it, or put details and pictures, on social media.
Here are six of the most horrifying ones.
1. Derek MedinaMiami, Florida has seen its share of infamous murderers. The one that shocked everyone, however, was that of 26-year-old Jennifer Alfonso, who was killed by her husband, then 31-year-old Derek Medina – the man who later became known as the "Facebook Killer."
2. Randy JanzenOn May 7, 2015, Randy Janzen, 50, of British Columbia, confessed to killing his daughter, wife and sister because he could not bear watching his daughter suffer from debilitating migraines anymore, and didn't want to have his wife and sister live with what he'd done.
The best little girl two parents could ever hope for... [she] excelled at so many things but slowly had to stop almost everything because of the migraines... I don't think anyone really knew how much pain Emily was in on a daily basis and the severe depression that these migraines caused her. Emily had tried everything to get better but nothing seemed to help her. I took a gun and shot her in the head and now she is migraine free and floating in the clouds on a sunny afternoon.'
He says he shot his wife Laurel because "a mother should never have [to] hear the news her baby has died," and that he killed his sister Shelly a couple of days later "because I did not want her to have to live with this shame I have caused all alone. Now my family is pain free (sic) and in heaven."
3. Gypsy Blanchard and Nicholas Godejohn

4. Josh DaviesIn October of 2010, the body of Rebecca Aylward, 15, was found bludgeoned to death in Maesteg, a small town in Wales. Her ex-boyfriend, Josh Davies, posted a very strange Facebook status, "I enjoyed a rather good day and a lovely breakfast."
Do you know how hard it is to break someone’s neck? She was facing away from me and I thought, 'This is it, I’m going to go for it'. I tried to break her neck. She was screaming so I picked up the rock and started to hit her with it. The worst part was feeling and seeing her skull give way.
