Agent 47695: The Manchester Teen Who Incited A Murder

In June 2003, a 14-year-old boy known as John was stabbed twice in an alley behind a row of shops in Altrincham, Greater Manchester, and his 16-year-old friend Mark told detectives a hooded stranger had attacked them. The investigation that followed took police through CCTV footage and tens of thousands of lines of internet chatroom messages, and it ended in a conviction no British court had ever handed down before. This one starts in a Manchester teen chatroom back in the MSN Messenger days, with a gifted grammar school kid who kept disappearing into his bedroom, a college boy with a part-time restaurant job, and a married MI5 spymistress who typed in all caps and had very big plans for both of them. It's a story about loneliness and a secret so elaborate that the judge said skilled fiction writers would struggle to invent it, and the whole thing comes down to 1 misspelled word.

1
00:00:00,000 --> 00:00:10,380
A teenage boy in Greater Manchester starts getting messages from a woman who says she

2
00:00:10,380 --> 00:00:13,100
works for British intelligence.

3
00:00:13,100 --> 00:00:17,700
She types everything in capital letters, and she has very big plans for him.

4
00:00:17,700 --> 00:00:23,680
She also has this odd habit of spelling the word maybe as "MYBYE".

5
00:00:23,680 --> 00:00:38,680
Keep that in mind because it's about to solve an attempted murder.

6
00:00:38,680 --> 00:01:05,240
Mark is a teenager in Greater Manchester, and by every account he's a pretty ordinary

7
00:01:05,240 --> 00:01:15,240
kid.

8
00:01:15,240 --> 00:01:25,600
Mark started spending time early in 2003 in an online chat room built for Manchester

9
00:01:25,600 --> 00:01:26,600
teenagers.

10
00:01:26,600 --> 00:01:40,880
Mark meets a girl in that chat room named Rachel.

11
00:01:40,880 --> 00:01:56,000
Every time Mark tries to meet her in person, the plan for some reason falls through.

12
00:01:56,000 --> 00:02:00,760
He's also pretty withdrawn, and he'll disappear into his bedroom for days at a time.

13
00:02:00,760 --> 00:02:05,160
John and Mark start hanging out, like in real life.

14
00:02:05,160 --> 00:02:11,000
Then a new name starts showing up in the chat room, a guy called Kevin, who calls himself

15
00:02:11,000 --> 00:02:12,080
a stalker.

16
00:02:12,080 --> 00:02:18,600
Kevin says he has kidnapped Rachel, and he says he'll rape and kill her unless Mark performs

17
00:02:18,600 --> 00:02:21,400
a sexual act on his webcam.

18
00:02:21,400 --> 00:02:26,560
Mark is so terrified for this girl he does exactly what Kevin tells him to do.

19
00:02:26,560 --> 00:02:31,640
Rachel gets released, supposedly, and then she drifts out of the chat room.

20
00:02:31,640 --> 00:02:35,040
You can't really blame a scared kid for believing it.

21
00:02:35,040 --> 00:02:38,960
Meanwhile, this chat room is eating into Mark's whole life.

22
00:02:38,960 --> 00:02:44,800
Mark gets up to around 12 hours a day online, and he still has that part time job.

23
00:02:44,800 --> 00:02:47,160
And then Janet arrives.

24
00:02:47,160 --> 00:02:51,640
Janet Dobinson says that she works for British intelligence, and she's a married woman in

25
00:02:51,640 --> 00:02:52,640
her 40s.

26
00:02:52,640 --> 00:02:57,640
And she tells Mark that the whole reason that she's hanging out in a Manchester teen chat room

27
00:02:57,640 --> 00:03:01,160
is to recruit him into MI5.

28
00:03:01,160 --> 00:03:05,280
Janet types absolutely everything in capital letters.

29
00:03:05,280 --> 00:03:11,120
And if you've ever had a boomer and two forward you a chain email in 2003, you know the energy.

30
00:03:11,120 --> 00:03:14,880
Janet reads like she's shouting at him from across the parking lot.

31
00:03:14,880 --> 00:03:17,640
And she has this other strange habit too.

32
00:03:17,640 --> 00:03:22,520
Janet spells the word maybe as "MY-BYE".

33
00:03:22,520 --> 00:03:25,240
Janet starts giving Mark loyalty tests.

34
00:03:25,240 --> 00:03:29,880
She tells him John's life is in danger, because John knows the code to a secret safe at the

35
00:03:29,880 --> 00:03:34,280
bottom of the Atlantic Ocean that only a few countries know about.

36
00:03:34,280 --> 00:03:39,840
That code is in John's head supposedly, and it makes him the most important person in

37
00:03:39,840 --> 00:03:44,520
Britain, which is why Mark has to get him out of school.

38
00:03:44,520 --> 00:03:49,440
Mark tells John's school that John has a dentist appointment, and it works.

39
00:03:49,440 --> 00:03:53,920
It's 2003, and a teenager says the word "Denist" and the door is swing open.

40
00:03:53,920 --> 00:03:58,360
This is well before you have to give them two forms of ID and a blood sample to check

41
00:03:58,360 --> 00:04:00,360
your kid out of school.

42
00:04:00,360 --> 00:04:05,680
The safety of the nation now hangs on a fake trip to the dentist, and the woman running

43
00:04:05,680 --> 00:04:09,600
the operation still hasn't found her caps lock key.

44
00:04:09,600 --> 00:04:15,600
Some of Janet's tests are sexual and humiliating, and Mark does every single one of them, because

45
00:04:15,600 --> 00:04:18,120
by now he's in love with her.

46
00:04:18,120 --> 00:04:20,280
He also gets a code name.

47
00:04:20,280 --> 00:04:23,920
He's agent 47695.

48
00:04:23,920 --> 00:04:27,840
Janet gives him an abort code in case a mission gets called off.

49
00:04:27,840 --> 00:04:31,400
The abort code is 6969.

50
00:04:31,400 --> 00:04:35,800
The prosecutor told the court the whole thing played out like an internet soap opera, with

51
00:04:35,800 --> 00:04:40,080
every character in storyline more fantastic than the last.

52
00:04:40,080 --> 00:04:42,240
And then the storyline turns.

53
00:04:42,240 --> 00:04:48,080
Janet tells Mark that John has a brain tumor, and he has about a week to live.

54
00:04:48,080 --> 00:04:52,680
Janet says John needs to be put out of his misery, and if Mark won't do it, she'll lose

55
00:04:52,680 --> 00:04:55,400
her job and the country will be in danger.

56
00:04:55,400 --> 00:04:59,640
And all of this is landing on a kid who a few months earlier was just chatting with a girl

57
00:04:59,640 --> 00:05:01,200
named Rachel.

58
00:05:01,200 --> 00:05:03,520
But he's not being asked to do it for free.

59
00:05:03,520 --> 00:05:05,360
His reward is enormous.

60
00:05:05,360 --> 00:05:08,000
Mark has promised 500,000 pounds.

61
00:05:08,000 --> 00:05:11,320
He's promised a gun and a meeting with the prime minister.

62
00:05:11,320 --> 00:05:14,080
He's promised a relationship with Janet.

63
00:05:14,080 --> 00:05:17,840
The married 40-something elite spy that he's fallen for.

64
00:05:17,840 --> 00:05:21,680
If you're a teenager in love with a spy, that list…

65
00:05:21,680 --> 00:05:24,400
I guess it sounds reasonable and real?

66
00:05:24,400 --> 00:05:26,920
I don't know, maybe I'm more skeptical.

67
00:05:26,920 --> 00:05:30,280
Janet asks Mark if he could stab someone.

68
00:05:30,280 --> 00:05:32,640
Mark says he hasn't really thought about it.

69
00:05:32,640 --> 00:05:35,240
Janet tells him to think, please.

70
00:05:35,240 --> 00:05:36,760
Mark says, "Okay."

71
00:05:36,760 --> 00:05:40,040
The final order comes through on the night of June 28th.

72
00:05:40,040 --> 00:05:43,560
Janet warns him to avoid the CCTV cameras.

73
00:05:43,560 --> 00:05:46,840
She tells him to wait 20 minutes before he calls for help.

74
00:05:46,840 --> 00:05:51,840
She promises she'll turn up, disguised as a detective, and make sure that he does not

75
00:05:51,840 --> 00:05:53,640
get arrested.

76
00:05:53,640 --> 00:05:56,520
Mark gets a hold of a kitchen knife the next day.

77
00:05:56,520 --> 00:06:01,360
Then he walks with John into an alley behind a row of shops in Al Trincham.

78
00:06:01,360 --> 00:06:06,000
Mark stabs John twice in the chest and the stomach.

79
00:06:06,000 --> 00:06:10,880
Nobody sends the abort code, which in case you forgot is 6969.

80
00:06:10,880 --> 00:06:16,160
Some accounts say Mark waited the full 20 minutes Janet asked for, and others say he called

81
00:06:16,160 --> 00:06:17,160
much sooner.

82
00:06:17,160 --> 00:06:22,640
I don't know which version is true, but the police did get called just before 8 that night.

83
00:06:22,640 --> 00:06:27,600
Mark tells them a hooded stranger stabbed his friend for no reason, and then he ran off.

84
00:06:27,600 --> 00:06:32,400
He describes this made-up attacker in such a precise detail that detectives believe him

85
00:06:32,400 --> 00:06:36,160
and they start hunting for this man that does not exist.

86
00:06:36,160 --> 00:06:39,800
Janet, of course, never shows up in her detective disguise.

87
00:06:39,800 --> 00:06:42,040
She never shows up at all.

88
00:06:42,040 --> 00:06:46,280
One of the wounds pierces John's kidney and tears into his liver.

89
00:06:46,280 --> 00:06:48,000
Doctors remove his gallbladder.

90
00:06:48,000 --> 00:06:52,920
He's critically ill in the hospital for a week, but he does survive.

91
00:06:52,920 --> 00:06:56,120
And they never mention this brain tumor that he apparently has.

92
00:06:56,120 --> 00:07:00,360
Police appeal for witnesses and they pull the CCTV footage from around the area.

93
00:07:00,360 --> 00:07:05,240
A few days later they watch the footage from the entrance to the alley, and only two people

94
00:07:05,240 --> 00:07:07,160
ever walk in.

95
00:07:07,160 --> 00:07:09,080
Just Mark and John.

96
00:07:09,080 --> 00:07:11,560
They show Mark the footage, and he breaks.

97
00:07:11,560 --> 00:07:17,680
He admits that he did it, and then he tells them the truth about Janet and MI5.

98
00:07:17,680 --> 00:07:19,440
This sees the computers.

99
00:07:19,440 --> 00:07:22,800
There are about 58,000 lines of chat.

100
00:07:22,800 --> 00:07:24,000
That's a lot of reading.

101
00:07:24,000 --> 00:07:27,680
It takes a while to break it all down, and the analyst on the case told Vanity Fair that

102
00:07:27,680 --> 00:07:32,840
if you printed it all out, the stack would reach about 46,000 feet.

103
00:07:32,840 --> 00:07:36,760
Somebody at Greater Manchester Police had to read every line of it, including the teenage

104
00:07:36,760 --> 00:07:42,040
chatter about football and clothes, and girls, and whatever else they talk about.

105
00:07:42,040 --> 00:07:47,280
And at first they thought they were hunting down a grown man, a predator hiding behind Janet.

106
00:07:47,280 --> 00:07:49,680
And then the analyst spots it.

107
00:07:49,680 --> 00:07:53,320
Janet spells maybe as M-Y-B-Y-E.

108
00:07:53,320 --> 00:07:56,480
John spells it that way too.

109
00:07:56,480 --> 00:08:00,840
Every character Mark trusted in that chat room was John.

110
00:08:00,840 --> 00:08:03,000
John built the whole thing.

111
00:08:03,000 --> 00:08:06,320
He built it so that Mark would kill him.

112
00:08:06,320 --> 00:08:11,360
Every caps lock letter that Janet ever typed came out of John's bedroom.

113
00:08:11,360 --> 00:08:14,400
The abort code was his to send.

114
00:08:14,400 --> 00:08:15,880
He never sent it.

115
00:08:15,880 --> 00:08:19,720
Mark could barely believe how gullible he had been.

116
00:08:19,720 --> 00:08:22,840
So why would a 14-year-old do this?

117
00:08:22,840 --> 00:08:26,440
John's barrister told the court that it grew out of infatuation.

118
00:08:26,440 --> 00:08:31,080
He said John wasn't sure whether he was gay or straight, and that he'd fallen in love

119
00:08:31,080 --> 00:08:32,480
with his new friend.

120
00:08:32,480 --> 00:08:35,040
The court also heard that John was depressed.

121
00:08:35,040 --> 00:08:38,880
He'd fallen out with his friends at school, and things were hard at home.

122
00:08:38,880 --> 00:08:43,600
The court heard the plot described as an extraordinary suicide attempt.

123
00:08:43,600 --> 00:08:49,440
One theory, and it's only a theory, is that John believed Mark could never love him back,

124
00:08:49,440 --> 00:08:53,740
and this was the only ending that he could picture, and building a whole world of spies

125
00:08:53,740 --> 00:08:57,920
and stalkers let him stay close to Mark right up until the end.

126
00:08:57,920 --> 00:09:01,320
Nobody knows exactly what was going on in his head.

127
00:09:01,320 --> 00:09:04,120
Mark pleads guilty to attempted murder.

128
00:09:04,120 --> 00:09:09,400
John pleads guilty to inciting his own murder and to perverting the course of justice.

129
00:09:09,400 --> 00:09:13,040
The prosecutor said that he wasn't aware of any other case in the world where somebody

130
00:09:13,040 --> 00:09:18,080
incited another person to murder them, and he called the case a stark warning about the

131
00:09:18,080 --> 00:09:19,080
internet.

132
00:09:19,080 --> 00:09:24,280
The judge said skilled writers of fiction would struggle to dream up a plot like this.

133
00:09:24,280 --> 00:09:30,560
Both boys walk out of court free, because the judge decided these weren't normal circumstances.

134
00:09:30,560 --> 00:09:33,480
Mark gets a two-year supervision order.

135
00:09:33,480 --> 00:09:35,800
John gets three years of supervision.

136
00:09:35,800 --> 00:09:40,280
John is banned from chat rooms, and he can only go online with an adult watching.

137
00:09:40,280 --> 00:09:44,800
The judge orders the boys to never contact each other ever again.

138
00:09:44,800 --> 00:09:50,880
Both men are now pushing 40 years old, and there's been no public reporting of any new trouble.

139
00:09:50,880 --> 00:09:54,640
You can stand behind either them in a check outline and never even know it.

140
00:09:54,640 --> 00:09:59,800
And the whole impossible thing came apart because of the way that some lonely kid spelled

141
00:09:59,800 --> 00:10:09,120
"maybe."

142
00:10:09,120 --> 00:10:13,600
But for listening to 10-minute murder, bingeable true crime stories.

143
00:10:13,600 --> 00:10:18,600
Hello, I'm Joe, I'm the host, and here's an email, subject something I appreciate.

144
00:10:18,600 --> 00:10:23,280
Hey, Joe, I don't think people realize how much work goes into making something sound

145
00:10:23,280 --> 00:10:24,280
effortless.

146
00:10:24,280 --> 00:10:28,800
I've worked in media before, and I can tell when somebody has put thought into the pacing,

147
00:10:28,800 --> 00:10:30,520
writing, and editing.

148
00:10:30,520 --> 00:10:32,040
Your show has that feeling.

149
00:10:32,040 --> 00:10:35,960
Anyway, from one media person to another, I appreciate the work.

150
00:10:35,960 --> 00:10:37,720
Chris and Columbia, Missouri.

151
00:10:37,720 --> 00:10:41,760
Chris, thank you for listening, thank you for the email, and you're right.

152
00:10:41,760 --> 00:10:49,000
I do try to make this sound like it is effortless, and it is 100% not effortless.

153
00:10:49,000 --> 00:10:55,600
More so today, though, unrelated to the writing, and the editing, and the pacing, and etc.

154
00:10:55,600 --> 00:10:58,480
The things that you just said, it's my voice.

155
00:10:58,480 --> 00:11:02,080
And if you're an OG listener, you know I go through this about two times a year, where

156
00:11:02,080 --> 00:11:05,200
I just sound like if a grizzly bear could talk.

157
00:11:05,200 --> 00:11:08,880
It's usually at the beginning of spring and the beginning of fall.

158
00:11:08,880 --> 00:11:11,000
And here we are, we're doing it again.

159
00:11:11,000 --> 00:11:14,600
And the frustrating part is, I feel mostly fine.

160
00:11:14,600 --> 00:11:18,080
Like when it first started, I didn't feel that great, but now I feel completely fine other

161
00:11:18,080 --> 00:11:22,280
than just being stuffy and sounding like I chewed glass for breakfast.

162
00:11:22,280 --> 00:11:26,600
But usually it'll last, you know, like a week or so, and then it'll disappear, and then

163
00:11:26,600 --> 00:11:29,080
pop back up, in about six months.

164
00:11:29,080 --> 00:11:34,720
Alright, if you're a new listener to this podcast, make sure you do me one huge favor.

165
00:11:34,720 --> 00:11:38,320
And that is to subscribe where you're listening right now.

166
00:11:38,320 --> 00:11:43,120
If you're an OG listener, been listening for a while, I want you to do me a huge favor.

167
00:11:43,120 --> 00:11:48,960
That is, today, or this week sometime, tell at least one friend or family member about

168
00:11:48,960 --> 00:11:49,960
this podcast.

169
00:11:49,960 --> 00:11:53,760
I don't give you homework very often, but I'm doing that today.

170
00:11:53,760 --> 00:11:58,880
So think of a person that you know could be into brief stories about true crime, and

171
00:11:58,880 --> 00:12:00,440
just mention the podcast to them.

172
00:12:00,440 --> 00:12:02,520
Tell them where they can listen to it.

173
00:12:02,520 --> 00:12:03,520
And that's going to do it.

174
00:12:03,520 --> 00:12:04,840
That's your episode for today.

175
00:12:04,840 --> 00:12:08,360
Thank you again for listening to 10 Minute Murder.
