The Pixy Stix Killer: How Ronald O'Bryan Weaponized Halloween

Halloween 1974 was supposed to be another night of trick-or-treating in Pasadena, Texas. Instead, it became the night that changed Halloween forever. When 8-year-old Timothy O'Bryan died from poisoned candy, investigators uncovered a twisted plot orchestrated by the one person who should have protected him most: his own father. Ronald O'Bryan didn't destroy Halloween by accident. He weaponized the holiday, turning a beloved childhood tradition into his personal murder weapon. This is the story of greed disguised as grief, a father's ultimate betrayal, and how one man's desperate scheme created fears that still haunt Halloween today.

00:00:00,000 --> 00:00:05,520
What if I told you that the person who created America's fear of poisoned Halloween candy

2
00:00:05,520 --> 00:00:08,160
was actually trying to commit the perfect murder?

3
00:00:08,160 --> 00:00:13,520
In 1974, a father in Texas handed his eight-year-old son a pixie stick

4
00:00:13,520 --> 00:00:16,160
within an hour that child was dead.

5
00:00:16,160 --> 00:00:19,760
Today, we're diving into the case that changed Halloween forever

6
00:00:19,760 --> 00:00:24,800
and asking the question, "How far would you go to solve your own problems?"

7
00:00:24,800 --> 00:00:49,680
[Music]

8
00:00:49,680 --> 00:00:56,000
October 31, 1974, started like any other Halloween night in Pasadena, Texas.

9
00:00:56,000 --> 00:00:59,200
The O'Brien family gathered with their neighbors, the Bates family,

10
00:00:59,200 --> 00:01:01,600
for dinner before trick or treating.

11
00:01:01,600 --> 00:01:05,600
Ronald O'Brien, an optician and deacon at his Baptist church,

12
00:01:05,600 --> 00:01:08,960
seemed like the perfect suburban dad, heading out with the kids.

13
00:01:08,960 --> 00:01:12,240
His wife stayed home while Ronald took their two children,

14
00:01:12,240 --> 00:01:14,880
eight-year-old Timothy and five-year-old Elizabeth,

15
00:01:14,880 --> 00:01:17,840
along with the Bates children through the neighborhood.

16
00:01:17,840 --> 00:01:21,520
But something was different about this particular Halloween outing.

17
00:01:21,520 --> 00:01:24,800
While the other kids and adults moved together as a group,

18
00:01:24,800 --> 00:01:27,280
Ronald kept separating himself.

19
00:01:27,280 --> 00:01:29,840
When they approached a house without lights on,

20
00:01:29,840 --> 00:01:31,840
the children naturally moved on.

21
00:01:31,840 --> 00:01:36,000
That's the universal symbol for we don't have candy or we're not home.

22
00:01:36,000 --> 00:01:37,200
Ronald didn't.

23
00:01:37,200 --> 00:01:40,960
He lingered behind and when he rejoined the group minutes later,

24
00:01:40,960 --> 00:01:44,240
he was waving five oversized pixie sticks,

25
00:01:44,240 --> 00:01:48,800
claiming, quote, "rich neighbors had given them the expensive treats."

26
00:01:48,800 --> 00:01:51,040
And here's where the story gets disturbing.

27
00:01:51,040 --> 00:01:55,680
A former Pasadena detective later recalled that O'Brien had those pixie sticks

28
00:01:55,680 --> 00:01:57,520
shoved up the sleeves of his raincoat.

29
00:01:57,520 --> 00:02:02,720
Ronald was carrying concealed weapons disguised as Halloween treats,

30
00:02:02,720 --> 00:02:05,440
premeditated and ready for distribution.

31
00:02:05,440 --> 00:02:08,880
Ronald distributed the candy strategically,

32
00:02:08,880 --> 00:02:11,200
one to Timothy, one to Elizabeth,

33
00:02:11,200 --> 00:02:15,440
two to the Bates children, and one to a random 10-year-old from their church

34
00:02:15,440 --> 00:02:16,880
that they encountered.

35
00:02:16,880 --> 00:02:20,960
When they returned home, Timothy wanted to try his pixie sticks before bed.

36
00:02:20,960 --> 00:02:23,520
The powder was difficult to get out,

37
00:02:23,520 --> 00:02:25,680
so his father helped him loosen it.

38
00:02:25,680 --> 00:02:28,480
Timothy immediately complained that it tasted bitter,

39
00:02:28,480 --> 00:02:32,320
and Ronald suggested that he wash it down with a little coolade.

40
00:02:32,320 --> 00:02:36,080
Within minutes, Timothy was vomiting and convulsing.

41
00:02:36,080 --> 00:02:39,920
He went limp in his father's arms and was dead in less than an hour.

42
00:02:40,480 --> 00:02:43,840
What appeared to be a tragic Halloween accident was actually

43
00:02:43,840 --> 00:02:46,560
the culmination of months of planning by a father

44
00:02:46,560 --> 00:02:49,600
who had decided his son was worth more dead than alive.

45
00:02:49,600 --> 00:02:51,040
Let me explain.

46
00:02:51,040 --> 00:02:55,840
Ronald Clark O'Brien had mastered the art of looking successful

47
00:02:55,840 --> 00:02:57,760
while failing spectacularly.

48
00:02:57,760 --> 00:03:02,160
On paper, he was everything in 1970's suburban community valued,

49
00:03:02,160 --> 00:03:05,920
a professional optician, a church deacon who sang in the choir,

50
00:03:05,920 --> 00:03:08,800
and ran the bus program, a married father of two.

51
00:03:09,360 --> 00:03:12,640
One pastor even called him a good Christian man

52
00:03:12,640 --> 00:03:14,240
and an above-average father.

53
00:03:14,240 --> 00:03:17,040
The reality painted a far different picture.

54
00:03:17,040 --> 00:03:21,280
Ronald had been fired from 21 jobs in 10 years for reasons,

55
00:03:21,280 --> 00:03:23,840
including negligence and fraudulent behavior.

56
00:03:23,840 --> 00:03:28,240
At the time of the murder, he was about to be fired again for suspected theft.

57
00:03:28,240 --> 00:03:33,280
His weekly salary of $150 wasn't covering his family's expenses,

58
00:03:33,280 --> 00:03:34,800
and he was drowning in debt.

59
00:03:34,800 --> 00:03:38,960
The numbers tell the story of a man in complete financial free fall.

60
00:03:38,960 --> 00:03:44,480
He owed over $100,000, roughly $640,000 in today's money.

61
00:03:44,480 --> 00:03:48,480
He had defaulted on bank loans, and his car was about to be repossessed.

62
00:03:48,480 --> 00:03:52,240
For someone maintaining the image of suburban success,

63
00:03:52,240 --> 00:03:55,520
these mounting failures created unbearable pressure.

64
00:03:55,520 --> 00:03:59,840
But Ronald had a plan that was as methodical as it was monstrous.

65
00:03:59,840 --> 00:04:06,480
And January 1974, he took out $10,000 life insurance policies on both of his kids,

66
00:04:06,480 --> 00:04:07,840
Timothy and Elizabeth.

67
00:04:08,400 --> 00:04:12,240
And September, he added another $20,000 policy on each child.

68
00:04:12,240 --> 00:04:18,240
Days before Halloween, he secured yet another $20,000 policy on each child.

69
00:04:18,240 --> 00:04:23,120
The insurance agency itself raised objections to these successive policies,

70
00:04:23,120 --> 00:04:24,720
but Ronald pushed it through.

71
00:04:24,720 --> 00:04:29,520
The total value reached $100,000, exactly matching his debt load.

72
00:04:29,520 --> 00:04:33,760
His wife knew nothing about these policies or their family's financial situation.

73
00:04:33,760 --> 00:04:36,880
Ronald was planning to solve his money problems

74
00:04:36,880 --> 00:04:40,080
by murdering his children and collecting insurance payouts.

75
00:04:40,080 --> 00:04:44,720
Ronald's preparation for murder began a year before Timothy's death.

76
00:04:44,720 --> 00:04:49,920
A chemist's acquaintance testified that O'Brien had asked him about the lethality of cyanide

77
00:04:49,920 --> 00:04:52,560
as early as the summer of 1973.

78
00:04:52,560 --> 00:04:57,520
He was researching murder methods while his family believed he was being a good father,

79
00:04:57,520 --> 00:04:59,120
a good Christian and husband.

80
00:04:59,120 --> 00:05:03,280
Shortly before Halloween, a clerk got a Houston chemical supply store

81
00:05:03,280 --> 00:05:06,640
that recalled a man in a beige or blue smock,

82
00:05:06,640 --> 00:05:08,800
similar to what an optician would wear,

83
00:05:08,800 --> 00:05:11,280
inquiring about purchasing cyanide.

84
00:05:11,280 --> 00:05:15,200
The man left when he discovered cyanide was only sold in bulk quantities.

85
00:05:15,200 --> 00:05:19,520
Ronald was literally shopping for the tools to kill his children.

86
00:05:19,520 --> 00:05:24,160
His weapon of choice was deceptively simple but terrifyingly effective.

87
00:05:24,160 --> 00:05:29,040
He opened the pixie sticks, replaced the top two inches of candy powder

88
00:05:29,040 --> 00:05:32,880
with potassium cyanide and he re-sealed them with staples.

89
00:05:32,880 --> 00:05:39,200
The single pixie sticks Timothy consumed contained enough cyanide to kill two adults,

90
00:05:39,200 --> 00:05:43,040
while the four others contained enough to kill three to four adults each.

91
00:05:43,040 --> 00:05:49,920
Ronald's plan relied on the emerging urban legend of stranger danger and poisoned Halloween candy.

92
00:05:49,920 --> 00:05:52,800
By giving poison treats to multiple children,

93
00:05:52,800 --> 00:05:56,720
he hoped to make Timothy's death appear random rather than targeted.

94
00:05:56,720 --> 00:06:01,280
It was a calculated attempt to hide familial murder behind societal fears.

95
00:06:01,280 --> 00:06:06,960
Police suspected Ronald almost immediately and their instincts proved correct.

96
00:06:06,960 --> 00:06:11,280
A Pasadena detective was struck by O'Brien's bizarre lack of emotion,

97
00:06:11,280 --> 00:06:14,320
noting that he didn't behave like most fathers would,

98
00:06:14,320 --> 00:06:19,040
after losing a child and didn't need to be physically restrained from rage or grief.

99
00:06:19,040 --> 00:06:22,560
His performance of grief was unconvincing to trained observers.

100
00:06:22,560 --> 00:06:25,360
Not that everyone grieves the same way,

101
00:06:25,360 --> 00:06:28,400
but when it's over the top fake, you can tell.

102
00:06:28,400 --> 00:06:30,880
Ronald's story crumbled under scrutiny.

103
00:06:30,880 --> 00:06:34,560
Initially, he claimed he couldn't remember which house gave him that candy,

104
00:06:34,560 --> 00:06:36,960
despite trick-or-treating on only two streets.

105
00:06:36,960 --> 00:06:41,920
When pressed, he eventually led police to the home of air traffic controller Courtney Melvin.

106
00:06:41,920 --> 00:06:44,080
But Melvin had an airtight alibi.

107
00:06:44,080 --> 00:06:47,040
He was working at the airport on Halloween night,

108
00:06:47,040 --> 00:06:49,200
verified by multiple witnesses.

109
00:06:49,200 --> 00:06:51,840
The evidence against Ronald became overwhelming.

110
00:06:51,840 --> 00:06:58,000
He was arrested on November 5, 1974, and indicted on one count of capital murder

111
00:06:58,000 --> 00:07:00,240
and four counts of attempted murder.

112
00:07:00,240 --> 00:07:02,960
Investigators uncovered his crushing debt,

113
00:07:02,960 --> 00:07:05,200
a suspicious life insurance policies,

114
00:07:05,200 --> 00:07:08,800
and testimony from the chemical supply salesman and chemist

115
00:07:08,800 --> 00:07:10,400
about his cyanide inquiries.

116
00:07:10,400 --> 00:07:14,400
Fates had intervened to save the other four children.

117
00:07:14,400 --> 00:07:17,760
One of the Bates children started to open his candy before his mother told him

118
00:07:17,760 --> 00:07:19,120
to save it for the next day.

119
00:07:19,680 --> 00:07:24,000
Most remarkably, the 10-year-old from the church was found a sleep in bed

120
00:07:24,000 --> 00:07:26,320
still holding the unopened candy,

121
00:07:26,320 --> 00:07:30,240
because O'Brien's stable was too secure for him to open by himself.

122
00:07:30,240 --> 00:07:36,400
Ronald's trial began May 5, 1975, and garnered national attention.

123
00:07:36,400 --> 00:07:38,480
The prosecution's case was devastating.

124
00:07:38,480 --> 00:07:43,520
His own wife testified against him, stating she knew nothing about the insurance policies,

125
00:07:43,520 --> 00:07:47,280
and that Ronald had forced Timothy to choose the pixie sticks.

126
00:07:47,280 --> 00:07:51,520
His sister-in-law and brother-in-law testified that on the day of Timothy's funeral,

127
00:07:51,520 --> 00:07:55,280
he talked about using the insurance money for a long vacation.

128
00:07:55,280 --> 00:07:59,120
Ronald made the fatal error of taking the stand in his own defense.

129
00:07:59,120 --> 00:08:02,240
His testimony was unconvincing and inconsistent,

130
00:08:02,240 --> 00:08:04,960
and his performance failed when it mattered the most.

131
00:08:04,960 --> 00:08:07,520
After just 46 minutes of deliberation,

132
00:08:07,520 --> 00:08:12,160
the jury found him guilty of capital murder and four counts of attempted murder.

133
00:08:12,160 --> 00:08:15,840
Even hardened criminals on death row despised O'Brien so much

134
00:08:15,840 --> 00:08:21,120
that they petitioned the warden for permission to hold the celebration when he was executed,

135
00:08:21,120 --> 00:08:23,040
and their request was granted.

136
00:08:23,040 --> 00:08:28,640
His crime was so universally condemned that men who had committed capital offences themselves

137
00:08:28,640 --> 00:08:30,640
found his actions unforgivable.

138
00:08:30,640 --> 00:08:37,600
On March 31, 1984, Ronald Clark O'Brien was executed by lethal injection.

139
00:08:37,600 --> 00:08:40,800
His final statement was a masterpiece of denial,

140
00:08:40,800 --> 00:08:44,560
declaring what is about to transpire in a few moments is wrong,

141
00:08:45,120 --> 00:08:48,240
and offering forgiveness to those involved in his execution,

142
00:08:48,240 --> 00:08:51,520
while never once confessing or apologizing for his actions.

143
00:08:51,520 --> 00:08:57,600
As his execution was carried out, a crowd gathered outside the prison and mockingly shouted,

144
00:08:57,600 --> 00:08:58,320
"Tricker treat."

145
00:08:58,320 --> 00:09:02,080
Ronald O'Brien did more than kill his son.

146
00:09:02,080 --> 00:09:05,840
He fundamentally changed how Americans celebrate Halloween.

147
00:09:05,840 --> 00:09:10,000
Despite his case being the only confirmed death from Poisoned Halloween candy,

148
00:09:10,000 --> 00:09:12,880
the fear he created became central to the holiday.

149
00:09:13,440 --> 00:09:15,760
The tragic irony is profound.

150
00:09:15,760 --> 00:09:21,440
A targeted murder motivated by greed became the foundation for nationwide fears of random,

151
00:09:21,440 --> 00:09:25,600
stranger danger. The phenomenon became known as Halloween sadism,

152
00:09:25,600 --> 00:09:31,200
and the focus on Poisoned candy obscured the more complex truth of familial betrayal.

153
00:09:31,200 --> 00:09:35,040
The consequences for Ronald's surviving family were devastating.

154
00:09:35,040 --> 00:09:38,240
Shortly after his conviction, his wife filed for divorce.

155
00:09:38,240 --> 00:09:42,080
Five-year-old Elizabeth was later adopted by her mother's new husband.

156
00:09:42,080 --> 00:09:44,720
Ronald's selfishness didn't end with Timothy's death.

157
00:09:44,720 --> 00:09:48,080
It shattered the lives of everyone he claimed to love,

158
00:09:48,080 --> 00:09:52,320
forcing his daughter to change her name to escape the shadow of her infamous father.

159
00:09:52,320 --> 00:09:56,560
Fifty years later, parents still inspect Halloween candy.

160
00:09:56,560 --> 00:09:59,440
Hospitals still offer free x-rays of treats,

161
00:09:59,440 --> 00:10:03,120
and communities still organize safe, trick-or-treating alternatives.

162
00:10:03,120 --> 00:10:05,520
Ronald O'Brien weaponized Halloween,

163
00:10:05,520 --> 00:10:10,240
turning a beloved childhood tradition into something parents approach with caution,

164
00:10:10,240 --> 00:10:11,360
and a little bit of fear.

165
00:10:11,920 --> 00:10:14,800
The real horror of this story centers on a father

166
00:10:14,800 --> 00:10:18,960
who calculated the exact monetary value of his children's lives.

167
00:10:18,960 --> 00:10:22,160
Decided the insurance payout was worth more than their futures,

168
00:10:22,160 --> 00:10:27,120
and then methodically planned their murders while maintaining the facade of being a loving parent.

169
00:10:27,120 --> 00:10:31,440
The ghost of Halloween isn't hiding in the shadows waiting to harm children.

170
00:10:31,440 --> 00:10:34,560
It's the specter of ultimate parental betrayal,

171
00:10:34,560 --> 00:10:39,360
reminding us that sometimes the real monsters are the ones we trust the most.

172
00:10:39,360 --> 00:10:49,360

Like this one, subject True Crime Burnout.

184
00:11:19,280 --> 00:11:22,080
Joe, do you ever take breaks from True Crime?

185
00:11:22,080 --> 00:11:27,040
If so, what do you watch, read, or listen to when you want something completely different?

186
00:11:27,040 --> 00:11:28,320
Mark in St. Louis.

187
00:11:28,320 --> 00:11:29,920
Great question, Mark.

188
00:11:29,920 --> 00:11:31,120
Thank you for the email.

189
00:11:31,120 --> 00:11:31,920
Stand up Comedy.

190
00:11:31,920 --> 00:11:33,280
Usually.

191
00:11:33,280 --> 00:11:35,760
That's about as opposite as I can get from True Crime,

192
00:11:35,760 --> 00:11:39,200
so I consume so much stand up comedy.

193
00:11:39,200 --> 00:11:41,520
But aside from that, I like to read mysteries.

194
00:11:41,520 --> 00:11:43,920
It's rare that I'll read a True Crime book.

195
00:11:43,920 --> 00:11:47,840
And I like a mystery, so it's usually some type of mystery,

196
00:11:47,840 --> 00:11:48,960
not always murder mystery.

197
00:11:48,960 --> 00:11:50,560
It can be like a sci-fi mystery,

198
00:11:50,560 --> 00:11:51,920
like what's happening here,

199
00:11:51,920 --> 00:11:53,200
a Stephen King situation.

200
00:11:53,200 --> 00:11:54,320
I like that a lot.

201
00:11:54,320 --> 00:11:55,760
And if you want a recommendation on that,

202
00:11:55,760 --> 00:11:58,080
read Project Hail Mary.

203
00:11:58,080 --> 00:11:59,520
It's by Andy Weir.

204
00:11:59,520 --> 00:12:02,640
It is one of the best books I've ever read, period.

205
00:12:02,640 --> 00:12:05,440
It's kind of a sci-fi mystery about space.

206
00:12:05,840 --> 00:12:08,000
But not like nerdy, not like in a nerdy way.

207
00:12:08,000 --> 00:12:10,000
It's more approachable.

208
00:12:10,000 --> 00:12:11,920
You won't feel like a dumb dumb reading that book.

209
00:12:11,920 --> 00:12:13,360
It's not going to go over your head.

210
00:12:13,360 --> 00:12:14,720
All right, that's going to do it.

211
00:12:14,720 --> 00:12:17,360
Thank you again for listening to 10 Minute Murder.

212
00:12:17,360 --> 00:12:18,560
I'll see you next time.
