 - (Voiceover) Number
 five, The Buried Body.
 In 2007, on the board
 simply known as "/b/,"
  the following post with a
  picture of a woman appeared.
It contained only one sentence,
  "If anyone can correctly
  guess their own post number,
 I will tell you
 where she is buried."
After many guesses,
one anonymous commenter
  managed to guess
  his own post number,
 and the original poster wrote
 a set of GPS coordinates.
While some on 4chan
dismissed it as a joke,
   the coordinates turned
   out to be very, very real.
 The very next day, a
 news article reported
  that a woman's body
  had been found,
 and the creator of the
 disturbing post was arrested.
Number four, The
Guatemalan Hand Grenade.
  In 2009, a 4chan
  user proudly bragged
  that he had found
  a live hand grenade
  while rummaging through his
  dead father's belongings.
 He then excitedly asked 4chan
 what he should do with it.
   After posting many photos
   and performing tests
  on the grenade to
  silence his critics,
  the user posted one
  final picture of him
  holding the grenade
  by just the firing
  pin over his toilet.
When another poster told
him to toss the grenade
 into his toilet, the
 anonymous kid with the grenade
  was never heard from again.
Later, after some digging,
4chan users found a news article
from a local paper in Guatemala
that reported that a 17-year-old
named Oscar Lopez died
 after he pulled the pin on a
 live grenade in his bathroom.
 The stunned users
 on 4chan quickly put
 two and two together.
 Number three, The
 Livestreamed Suicide.
   4chan is known for its raw
   and unfiltered content.
  And this post certainly puts
  even some of the craziest
  posts on the site to shame.
   The following was
   posted one evening
 by a college student in 2013:
"Hi /b/.
  This is it.
  Tonight, I will be
  ending my own life.
 I've been spending the last
 hours making the preparations
  and I'm ready to
  go through with it.
As an oldfag who's been
on 4chan since 2004,
   I thought I would finally
   give back to the community
   in the best way possible.
I am willing to un-hero
on cam for you all.
 All that I request is for
 you guys to link me to a site
where I am able to
stream it for you guys.
  Then I will gladly
  fulfill my promise."
 Eventually, the users
 on 4chan directed him
  to a livestreaming website,
where he started drinking vodka
and taking pills on camera.
   Some users begged him
   not to take his own life,
  while others laughed
  and encouraged him.
   He then started a fire in
   the corner of his room.
   After the fire
   started to spread,
 the college student ran under
 his bed with his laptop.
   The final moments of his
   livestream show him hiding
 under his bed as his room
 fills with suffocating smoke.
Eventually, firefighters are
seen carrying his lifeless body
out of his
smoke-filled dorm room.
  It turns out this disturbing
  post was no prank.
  Local news reported
  a university student
tried to kill himself by
starting a fire, but thankfully,
  the articles claimed he was
  recovering in the hospital.
In April of 2013, a post
   from a Virginia
   community college student
   appeared on 4chan.
  It read, "Hey /b/ it's time.
  My name is Neil
  MacInnis and I go to
  New River Community College
  in Christianburg, Virginia,
  ten minutes away
  from Virginia Tech.
I'm gonna give y'all the details
  because the news
  never gets it right.
 Stevens 320 shotgun,
 buck shots and slugs.
 Wanna listen?
   If that link doesn't work,
 search New River
 Valley Public Safety.
   I'm a bit nervous because
   I've never really handled
 a shotgun, but a few times
 with the Christianburg Police.
  Anyways, this is not
  a high-score game,
   but actually a lesson,
   that's why I'm at school.
  Wanna see what I look like?
   Also pic-related, I'm here
   at school writing this.
 Wish me luck."
 Shortly after, police reported
   that an active shooter
   was in the New River Mall.
   The shooter tried
   to use his shotgun
to massacre mall shoppers, just
as he promised in his post.
  It was later revealed that a
  teenager name Neil MacInnis
  was indeed the
  creator of the post.
 Neil wounded two people before
 police managed to subdue him.
   Neil later pleaded guilty
   to two felony charges,
and is currently serving
a 38-year jail sentence.
  And perhaps one of the most
  disturbing posts on 4chan,
   an anonymous user started
   a thread that simply said,
  "Turns out it's way harder
  to strangle someone to death
 than it looks in the movies."
 Attached to his post
 was a disturbing image
of a worman who had
been strangled to death.
 Some on 4chan were skeptical,
  while others simply laughed
  with the deranged poster.
   Later, the creator
   posted more images
  of the strangled woman, and
  confessed to murdering her.
  He said, "She
  fought so damn hard.
Check the news for Port Orchard,
Washington in a few hours.
  Her son will be home
  from school soon.
  He'll find her,
  then call the cops.
   I just wanted to share the
   pics before they find me.
I bought a BB gun that
looks realistic enough.
When they come,
I'll pull it and it
will be suicide by cop.
I understand the doubts,
just check the news.
 I have to lose my phone now."
 The same day, a local
 news station reported
 that police were investigating
 a suspected homicide
involving the death of a
woman in her early 30's,
   who was found dead by her
   13-year-old son at home
   in the Port Orchard area.
 That evening, KOMO 4
 news anchor Russ Bowen
   tweeted a photo
   outside the house
where the woman was found dead.
 A few days later, a
 man named David Kalac
 was taken into
 custody by the police.
 David was in fact the creator
 of the disturbing 4chan post
 and took the sickening photos
 he posted in the thread.
  He is currently facing a
  sentence of life in prison.
