Lyda Southard: The Serial Widow Who Cooked with Arsenic
Lyda Southard wanted a quiet life. She wanted a husband, a child, maybe a porch to sit on and watch things grow. What she left behind instead was a string of dead husbands, a trail of insurance payouts, and enough arsenic to make even the most optimistic pharmacist raise an eyebrow.
In this episode, we follow Lyda from rural Idaho to Honolulu, through five marriages, four funerals, one prison escape, and a shocking discovery that unraveled the truth she kept so carefully hidden. Was she just a magnet for tragedy, or was there a far more calculated pattern behind the pain?
It’s the story of America’s first known female serial killer, served up in a way that makes you lean in and question everything you thought you knew about grief, luck, and motive.

00:00:00,000 --> 00:00:03,400
Sometimes bad luck looks a lot like premeditation.
2
00:00:03,400 --> 00:00:07,500
One woman, five husbands, a few tragic kids,
3
00:00:07,500 --> 00:00:09,900
and a suspicious amount of arsenic.
4
00:00:09,900 --> 00:00:12,700
Thing is, people kept dying around light as south-eared,
5
00:00:12,700 --> 00:00:14,600
and she kept collecting life insurance
6
00:00:14,600 --> 00:00:17,800
like it was a loyalty program she was signed up for.
7
00:00:17,800 --> 00:00:21,300
This story takes us from rural Idaho with a prison escape
8
00:00:21,300 --> 00:00:23,700
and a saw hidden in plain sight.

Let's get into it.
14
00:00:36,900 --> 00:00:59,900
[Music]
15
00:00:59,900 --> 00:01:04,900
LIDA Trueblood was born in Keatsville, Missouri in 1892.
16
00:01:04,900 --> 00:01:08,300
Life was tough, or just about everybody back then.
17
00:01:08,300 --> 00:01:11,600
But LIDA seemed to pull the short straw more often than not.
18
00:01:11,600 --> 00:01:15,300
At 20 years old, she married a farmer named Robert Dooley.
19
00:01:15,300 --> 00:01:18,800
The two of them moved around trying to find a place that felt like home.
20
00:01:18,800 --> 00:01:21,900
Eventually, they landed in Twin Falls, Idaho,
21
00:01:21,900 --> 00:01:25,300
where Robert and his brother Edward found work on a ranch.
22
00:01:25,300 --> 00:01:27,600
LIDA had plenty to do.
23
00:01:27,600 --> 00:01:30,100
She kept the house running, made sure the men were fed,
24
00:01:30,100 --> 00:01:32,300
and looked after their daughter Lorraine.
25
00:01:32,300 --> 00:01:35,300
Lorraine was born a year after the wedding,
26
00:01:35,300 --> 00:01:39,900
and by all appearances, she was just the beginning of what looked like a growing family.
27
00:01:39,900 --> 00:01:41,900
But that never happened.
28
00:01:41,900 --> 00:01:48,300
Typhoid fever was everywhere, and medical care in 1915 was more guesswork than help.
29
00:01:48,300 --> 00:01:50,300
The first to get sick was Edward.
30
00:01:50,300 --> 00:01:55,700
He came down with a fever, nonstop vomiting, and sharp pain that did not let up.
31
00:01:55,700 --> 00:01:57,500
Doctors called it typhoid.
32
00:01:57,500 --> 00:02:01,700
Edward died later that year with his brother and family by his side.
33
00:02:01,700 --> 00:02:04,700
After every attempt to save him, failed.
34
00:02:04,700 --> 00:02:09,300
Not long after Edward's death, tragedy hit the Dooley family again.
35
00:02:09,300 --> 00:02:12,100
This time, it was three-year-old Lorraine.
36
00:02:12,100 --> 00:02:15,700
LIDA knew exactly what it caused her daughter's sudden decline.
37
00:02:15,700 --> 00:02:19,100
She'd seen Lorraine drinking from the well on their ranch.
38
00:02:19,100 --> 00:02:22,700
The same well that was later be found to be contaminated.
39
00:02:22,700 --> 00:02:25,300
Whatever was in that water hit fast.
40
00:02:25,300 --> 00:02:30,100
Lorraine died shortly after her uncle, leaving LIDA and Robert crushed.
41
00:02:30,100 --> 00:02:33,100
And then, Robert got sick too.
42
00:02:33,100 --> 00:02:35,700
He had also had water from the well.
43
00:02:35,700 --> 00:02:38,100
The same symptoms hit him just as hard.
44
00:02:38,100 --> 00:02:42,700
Fever, weakness, pain, and no real way to recover.
45
00:02:42,700 --> 00:02:49,300
He became completely dependent on LIDA, who took care of him through every stage of his slow, brutal decline.
46
00:02:49,300 --> 00:02:56,100
By the time Robert died, LIDA had lost her child, her husband, and her brother-in-law in the span of a year.
47
00:02:56,100 --> 00:02:58,300
She was the last one left.
48
00:02:58,300 --> 00:03:02,700
With no family and no income, LIDA packed it up and left the ranch.
49
00:03:02,700 --> 00:03:07,300
She moved into town, hoping for work, maybe even a little piece.
50
00:03:07,300 --> 00:03:11,900
But as much as her life had just unraveled, she wasn't entirely empty-handed.
51
00:03:11,900 --> 00:03:15,100
Turns out Robert and Edward had planned ahead.
52
00:03:15,100 --> 00:03:18,700
They'd each taken out $2,000 life insurance policies,
53
00:03:18,700 --> 00:03:21,100
naming each other as the beneficiaries.
54
00:03:21,100 --> 00:03:22,700
The idea was simple.
55
00:03:22,700 --> 00:03:26,700
If one died, the other would be able to take care of LIDA and Lorraine.
56
00:03:26,700 --> 00:03:31,900
When Edward died, Robert collected $2,000 from his brother's life insurance.
57
00:03:31,900 --> 00:03:37,500
After Robert passed, LIDA inherited what was left, including his policy payout.
58
00:03:37,500 --> 00:03:42,700
She probably didn't walk away with the full $4,000, but it was close.
59
00:03:42,700 --> 00:03:47,100
And today's money, that would be about $130,000.
60
00:03:47,100 --> 00:03:53,900
LIDA had lost her entire family, but now she had a small financial cushion, something to help her reset.
61
00:03:53,900 --> 00:03:58,300
But more than the money, she wanted another shot at having a family.
62
00:03:58,300 --> 00:04:04,700
She found that, in William McHaffell, a widowed waiter in Twin Falls with a three-year-old daughter.
63
00:04:04,700 --> 00:04:07,900
William had been through heartbreak, and so had LIDA.
64
00:04:07,900 --> 00:04:12,300
Marrying him and she suddenly had a husband and a little girl in her life again.
65
00:04:12,300 --> 00:04:15,100
And for a minute, it looked like a fresh start.
66
00:04:15,100 --> 00:04:20,700
But this was the early 1900s, where illness was always waiting just off stage.
67
00:04:20,700 --> 00:04:25,100
The little girl got sick first. It came fast and left even faster.
68
00:04:25,100 --> 00:04:28,700
There was no time to help her. William was devastated.
69
00:04:28,700 --> 00:04:33,500
Twin Falls held too many painful memories now, so the couple moved to Montana.
70
00:04:33,500 --> 00:04:36,100
That lasted about a year.
71
00:04:36,100 --> 00:04:39,900
William came down with the flu, then diptheria.
72
00:04:39,900 --> 00:04:44,700
LIDA, who had already spent too much time as a caretaker, tried to nurse him through it.
73
00:04:44,700 --> 00:04:47,900
But he couldn't keep anything down. He got weaker.
74
00:04:47,900 --> 00:04:49,900
And he died that fall.
75
00:04:49,900 --> 00:04:52,700
This time, LIDA had planned ahead.
76
00:04:52,700 --> 00:04:55,500
She had told William what happened to her first family.
77
00:04:55,500 --> 00:05:02,700
He understood grief, so when she asked him to take out a life insurance policy to protect her and his daughter, he agreed.
78
00:05:02,700 --> 00:05:07,100
He applied, made the first payment, and never made the second.
79
00:05:07,100 --> 00:05:11,100
No payouts, no financial backup, just more loss.
80
00:05:11,100 --> 00:05:13,100
And once again, LIDA moved on.
81
00:05:13,100 --> 00:05:16,300
She found another man and got married again.
82
00:05:16,300 --> 00:05:20,300
About five months after losing William, LIDA married again.
83
00:05:20,300 --> 00:05:25,500
Husband number three was Harlan Lewis, a car salesman from Billings, Montana.
84
00:05:25,500 --> 00:05:28,300
Maybe LIDA thought her luck was finally turning.
85
00:05:28,300 --> 00:05:29,900
It was not.
86
00:05:29,900 --> 00:05:34,300
Within a few months, Harlan came down with what doctors diagnosed as gastroenteritis.
87
00:05:34,300 --> 00:05:37,300
He could not eat. He was in constant pain.
88
00:05:37,300 --> 00:05:39,500
Vomiting diarrhea, the works.
89
00:05:39,500 --> 00:05:41,900
It didn't take long. Harlan died.
90
00:05:41,900 --> 00:05:47,900
And LIDA became the sole beneficiary of his fully paid $5,000 life insurance policy.
91
00:05:47,900 --> 00:05:50,300
She packed up in left Montana.
92
00:05:50,300 --> 00:05:54,500
Back in Idaho, she met a ranch foreman named Edward Mayer.
93
00:05:54,500 --> 00:05:56,500
They got married not long after meeting.
94
00:05:56,500 --> 00:05:59,100
And within a month, Edward was sick.
95
00:05:59,100 --> 00:06:01,500
This time, it was Typhoid fever.
96
00:06:01,500 --> 00:06:05,300
Edward had applied for a $10,000 life insurance policy.
97
00:06:05,300 --> 00:06:07,900
But the paperwork had not been finalized.
98
00:06:07,900 --> 00:06:11,500
So when he died, LIDA walked away with nothing.
99
00:06:11,500 --> 00:06:15,100
But Edward's death did not follow the same script as others.
100
00:06:15,100 --> 00:06:18,300
When he first fell ill, he was admitted to the hospital.
101
00:06:18,300 --> 00:06:20,100
Doctors expected him to recover.
102
00:06:20,100 --> 00:06:21,500
He was doing better.
103
00:06:21,500 --> 00:06:24,100
Things looked promising for him.
104
00:06:24,100 --> 00:06:25,700
And then he came home.
105
00:06:25,700 --> 00:06:31,500
After just a short time in LIDA's care, the condition suddenly turned for the worse.
106
00:06:31,500 --> 00:06:34,100
He died soon after coming home.
107
00:06:34,100 --> 00:06:37,100
Edward Mayer's death caught everyone off guard.
108
00:06:37,100 --> 00:06:41,500
His doctor's thought he was recovering. His friends did not expect to lose him.
109
00:06:41,500 --> 00:06:44,500
But there was one person who was not surprised.
110
00:06:44,500 --> 00:06:45,900
Earl Dooley.
111
00:06:45,900 --> 00:06:48,500
He was the local chemist and twin falls-in.
112
00:06:48,500 --> 00:06:52,100
More importantly, a cousin of Robert and Edward Dooley.
113
00:06:52,100 --> 00:06:54,500
LIDA's first husband and brother-in-law.
114
00:06:54,500 --> 00:06:56,900
Earl had seen enough loss in that family.
115
00:06:56,900 --> 00:07:00,700
And now another man was dying too soon after marrying LIDA.
116
00:07:00,700 --> 00:07:02,700
His suspicions kicked in.
117
00:07:02,700 --> 00:07:06,500
After Edward Mayer died, an inspection of his throat revealed signs
118
00:07:06,500 --> 00:07:08,300
that set off alarm bells.
119
00:07:08,300 --> 00:07:11,500
There were burns that looked like they could have come from poison.
120
00:07:11,500 --> 00:07:13,500
Earl knew what he was looking at.
121
00:07:13,500 --> 00:07:15,500
He recognized arsenic.
122
00:07:15,500 --> 00:07:19,500
He pushed to have the bodies of his cousins and young Lorraine exhumed.
123
00:07:19,500 --> 00:07:22,900
If they had been poisoned too, it would show.
124
00:07:22,900 --> 00:07:24,900
And it did.
125
00:07:24,900 --> 00:07:26,300
Tests confirmed it.
126
00:07:26,300 --> 00:07:29,100
All three had arsenic in their systems.
127
00:07:29,100 --> 00:07:30,700
They had been murdered.
128
00:07:30,700 --> 00:07:34,600
Now the question became, how was LIDA getting her hands on it?
129
00:07:34,600 --> 00:07:38,000
Arsenic was not hard to find back then, but buying large amounts
130
00:07:38,000 --> 00:07:39,600
would have raised eyebrows.
131
00:07:39,600 --> 00:07:42,000
She needed something subtle.
132
00:07:42,000 --> 00:07:44,800
That is where a local shopkeeper came in.
133
00:07:44,800 --> 00:07:48,200
He told investigators that LIDA had been buying fly paper.
134
00:07:48,200 --> 00:07:49,500
A lot of it.
135
00:07:49,500 --> 00:07:51,800
The kind laced with arsenic.
136
00:07:51,800 --> 00:07:56,000
LIDA had been boiling the fly paper and water to extract the poison.
137
00:07:56,000 --> 00:08:00,300
Once it cooled, she collected the powder that settled to the bottom of the pot.
138
00:08:00,300 --> 00:08:02,800
That powder went into food.
139
00:08:02,800 --> 00:08:04,500
And then came the waiting.
140
00:08:04,500 --> 00:08:07,000
Arsenic poisoning is not quick.
141
00:08:07,000 --> 00:08:08,200
It drags on.
142
00:08:08,200 --> 00:08:13,200
The victims would suffer constant nausea, stomach pain, vomiting and diarrhea.
143
00:08:13,200 --> 00:08:15,700
It was miserable and it lasted.
144
00:08:15,700 --> 00:08:18,900
LIDA had fed this to people she claimed to love.
145
00:08:18,900 --> 00:08:21,600
And then she watched them die slowly.
146
00:08:21,600 --> 00:08:23,800
With enough evidence tying her to the murders,
147
00:08:23,800 --> 00:08:26,300
police were ready to arrest LIDA.
148
00:08:26,300 --> 00:08:28,300
But she was already gone.
149
00:08:28,300 --> 00:08:33,300
They tracked her down in Honolulu, where she was living under a new name and a new marriage.
150
00:08:33,300 --> 00:08:37,000
Her fifth husband was Navy officer Paul Southerd.
151
00:08:37,000 --> 00:08:43,100
The only thing that may have saved him was the fact that he refused to take out a separate life insurance policy.
152
00:08:43,100 --> 00:08:47,300
He figured LIDA would be fine with the government pension if anything happened to him.
153
00:08:47,300 --> 00:08:49,500
No need to spend the extra money.
154
00:08:49,500 --> 00:08:54,100
When police finally caught up with her and brought charges for the murders of her husband's and daughter,
155
00:08:54,100 --> 00:08:55,800
Paul was stunned.
156
00:08:55,800 --> 00:08:57,200
But he stood by her.
157
00:08:57,200 --> 00:08:58,500
So did her family.
158
00:08:58,500 --> 00:09:04,100
They believed her when she said that she must have been an asymptomatic carrier of typhoid fever.
159
00:09:04,100 --> 00:09:06,100
That she never meant to hurt anyone.
160
00:09:06,100 --> 00:09:09,000
The deaths were a tragic coincidence.
161
00:09:09,000 --> 00:09:11,300
The jury did not believe it.
162
00:09:11,300 --> 00:09:16,600
LIDA was found guilty of murdering Edward Mayer and sentenced to ten years to life.
163
00:09:16,600 --> 00:09:19,500
She was sent to the old Idaho State Penitentiary.
164
00:09:19,500 --> 00:09:23,300
But she did not exactly keep a low profile there either.
165
00:09:23,300 --> 00:09:26,300
At one point, she was the only woman in the prison.
166
00:09:26,300 --> 00:09:28,100
She arranged the furniture.
167
00:09:28,100 --> 00:09:29,100
She decorated.
168
00:09:29,100 --> 00:09:32,500
She cooked meals for the warden's wife and handled the sewing.
169
00:09:32,500 --> 00:09:35,200
On paper, she was a model inmate.
170
00:09:35,200 --> 00:09:37,800
And she still had some game left in the tank.
171
00:09:37,800 --> 00:09:41,700
LIDA convinced a prison guard to let her keep a saw in her room.
172
00:09:41,700 --> 00:09:46,600
She then recruited a male prisoner who was out on bail at the time to help her escape.
173
00:09:46,600 --> 00:09:49,500
He thought they were going to run off together and get married.
174
00:09:49,500 --> 00:09:51,300
LIDA had other plans.
175
00:09:51,300 --> 00:09:55,900
She ditched him and fled to Denver, Colorado, where she got married yet again.
176
00:09:55,900 --> 00:09:59,300
This time to a housekeeper named Harry Whitlock.
177
00:09:59,300 --> 00:10:02,200
There are two stories about how she was later caught.
178
00:10:02,200 --> 00:10:06,300
One says the authorities tracked her down and told Harry who she really was.
179
00:10:06,300 --> 00:10:11,900
The other says LIDA had grown attached to Harry's young son and confessed to Harry herself,
180
00:10:11,900 --> 00:10:15,900
asking him to turn her in before she could hurt anyone else.
181
00:10:15,900 --> 00:10:20,500
Either way, she was arrested and sent back to Idaho to finish her sentence.
182
00:10:20,500 --> 00:10:24,400
LIDA Southard was released on probation in 1941.
183
00:10:24,400 --> 00:10:32,400
She died of a heart attack in 1958, closing the final chapter on the life of Idaho's first known serial killer.
184
00:10:32,400 --> 00:10:45,800
