A Murder Mystery in Aledo, Illinois

 

Allie Dool

In September 1902, Aledo, Illinois, found itself plunged waist-deep into the biggest murder mystery the town had ever encountered. Marie Antoinette Dunlap (Tona) stood accused of killing her best friend, Mary Alma Dool (Allie), to get her $4.00 a-week job as a clerk at Felix’s Store.

At first, the authorities considered Allie Dool’s death an unfortunate accident. The coroner’s inquest said the same thing. It was accidental poisoning.

A few days later, suspicion centered on Tona Dunlap. 

State’s Attorney Will J. Graham questioned the decision of the coroner’s inquest and began looking into the details of Allie’s death. He tried to question Tona but met a brick wall. Every time he asked a question, she said her attorney advised her not to say anything. 

Then Dr. Carter, the pharmacist at Craig’s Drug Store, told Graham Tona bought five cents worth of strychnine on Sunday, August 3. 

That gave the state’s attorney the ammunition he needed to go after Tona Dunlap. The next person he spoke to was Margaret Miller. She told him about her shopping trip with Tona Dool the day Allie died.

“How many chocolates did Tona give Mrs. Dool?”

“Four, I think. They were all stuck together.”

“Did Miss Dool reach into the bag and take them out, or did Tona take the candy out and hand it to her?”

“Tona took four pieces, which stuck together, out of the bag and gave them to Mrs. Dool. She said something about them being mashed.”

It seemed like a trivial question, but the entire case depended on who put the poison chocolates in Allie Dool’s hand. If she chose them herself, it was most likely an accident. If Tona selected the candies for her, murder was more likely.

The state’s attorney had Tona arrested based on evidence showing she bought strychnine and selected which candies to give Allie.

Later, Margaret Miller changed her story at the preliminary hearing and said Tona Dunlap did not pick the candies she gave Allie out of the bag. “Allie picked the pieces out of the bag herself.”

Maynard Marquis testified: “Tona and Miller came into the store after 5 o’clock. They were sitting at the counter. I saw Mrs. Dool reach over and get some candy out of the sack that was sitting on the counter.” Marquis said he was unsure of anything at the preliminary hearing, so things must have cleared up for him.

The grand jury issued a perjury indictment against Margaret Miller for changing her testimony midstream, saying it looked like she was protecting her friend.

The way the prosecutor saw it, there were only three possibilities. 1) Allie was accidentally poisoned by some unknown method. 2) Allie killed herself because of her recent breakup with Frank Owens, or 3) Tona killed her.

The question was: Who put the strychnine in Allie’s chocolate? And why didn’t Tona and Margaret Miller die if they ate just as much chocolate? Because they lived and Allie didn’t, that made Tona appear guilty.

Allie’s father said it best. “If it was an accident, it was strange that Allie got so much of the poison and the others so little.” He stopped short of blaming anyone for his daughter’s death.

Some people thought Allie Dool might have killed herself. She had acted strangely since her engagement to Frank Owens ended because he enjoyed whiskey more than her. The couple had been engaged for nearly six years, and then Frank broke it off.

Frank Owens, 33, testified at the trial. He had worked at Felix’s Store for twelve years. He left when Allie got a job there. They broke up in March because he couldn’t stop drinking.

If Tona killed Allie, what was her motive? Did she really kill her best friend for a $4.00-a-week job at Felix’s Dry Goods store? That’s what the prosecution aimed to tell jurors.

Attorneys examined three hundred people before selecting the jury.

The first day was devoted to determining the facts of the case.

Tona Dunlap bought five cents worth of strychnine at Craig’s Drug Store on Sunday, August 3. On Wednesday, August 6, she purchased five cents’ worth of chocolate candies at Miller’s Grocery Store. 

The next afternoon, Thursday, August 7, Tona purchased another nickel’s worth of candy. Margaret Miller, a boarder at her mother’s house, was with her. They ate the candy as they walked to Felix’s Dry Goods store, where Allie Dool worked.

Dool was busy waiting on customers, so they left and walked up to the depot and waited for the 4:50 train. They headed back to Felix’s at about 5 p.m. The customers had cleared out by then, so the girls visited for a while. 

Tona asked Allie if she wanted some candy. 

“Yes, indeed,” replied Allie. “You know I never refuse candy.”

Tona took a bite of the candy, then spat it out, complaining it tasted bitter. She tried another piece, but it was just as bitter. “I asked Miss Dool if she would excuse me if I should spit it on the floor,” said Tona. “She said ‘certainly,’ and I spit the candy out on the floor.”

Margaret Miller verified Tona’s comment about the candy being bitter and spitting it out. “Tona was eating a piece when she spoke about it being bitter and asked permission of Miss Dool to spit it out on the floor.”

That should have been a clue for the other two girls that something was wrong with the candy. But no, they ate it anyway. Unfortunately, neither the prosecution nor the defense focused on this issue.

Later that night, after learning Dool was poisoned, Tona experienced similar symptoms. Dr. Carter determined she wasn’t poisoned. He wrote it off as a nervous reaction after hearing what happened to her friend. 

Allie kept eating the candy after Tona and Margaret Miller left. She began convulsing about fifteen minutes later. By 10 p.m., she was dead.

Before she died, Allie told Doctor M. G. Reynolds, “The candy Lena gave me was so bitter I put part of it out. It is near the muslin counter.” I imagine that means she vomited, but neither side attempted to check.

As she was dying, Allie muttered, “I wonder why Lena did this?” “Why did Lena give me this?”

Mr. Felix testified about finding Allie going into convulsions when he returned from supper. She said the candy Tona brought her tasted “so bitter.”

Frank Minor, the grocer who sold Tona the candy, said nothing was wrong with it.

And finally, Dr. J. Allen Patton testified he found traces of strychnine in the candy Tona gave Allie and the contents of the girl’s stomach.

Dr. Patton explained how he conducted the test to prove Allie was poisoned with strychnine. He used a live frog.

“A glass tube was filled with the solution,” said the doctor. “Then a live frog was held so its mouth was open, and a drop of the solution allowed to fall in its throat.

“Then the frog was placed under a glass jar.

“It soon manifested symptoms of uneasiness, turning its head away from the light. Soon, its movements became convulsive. Its hind legs became rigid, and its head was thrown backward. Its forelegs were crossed on its breast. In fifty minutes, the frog was dead.”

Prosecutor Graham focused on the job at Felix’s Store.

“The defendant had a fixed, almost insane idea,” said Graham, “that she was going to work in Felix’s Store.” A job there remained at the top of her mind for two years. She told nine people, “She had a definite arrangement for taking a clerkship in the store.” 

 “The only thing standing in her way,” said Graham, pointing toward the defendant, “was Allie Dool. What was to be done? Remove her. Five days after Allie Dool died in the agony of strychnine poisoning, Tona Dunlap applied for her position.”

“The candy Tona gave me was so bitter,” Graham repeated the dying girl’s words. “I wonder why she gave it to me?” In his mind, the dying girl was telling the world who killed her.

If Tona were her friend, she didn’t act like it. Shortly after Allie’s death, Tona told her family: It was “God’s will.” Allie “was better off as she had nothing to live for. Her life had been such a dreary one.”

Graham told the jury that it didn’t sound like a friend talking.

The prosecution insisted Tona bought the strychnine from Craig’s Drug Store, intending to poison Allie. The defense said she used it as a cure for corns.

Dr. Carter, the druggist who sold Tona the strychnine, said the girl bet he “couldn’t guess what it was wanted for?”

“I remarked that I guessed she was going to try it on the neighbor’s cat. Then she told me she wanted it for corn medicine. I told her she must be mistaken,” said the doctor, “and suggested that she meant arsenic, but she assured me she was right, as she had used strychnine for a corn before. So, I sold the girl seven grains.”

Tona’s sister, Bessie Dunlap, explained how Tona applied the strychnine.

She sprinkled the powder on a pink cloth, “pulverizing it between her thumb and finger as she did so. Then she bound the cloth around her toe and tied it with a string.” When she finished, she threw the paper envelope that contained the poison away.

And what about the candy Cora McMullen gave Allie Dool a half-hour before Tona stopped by the store? Maybe it contained poison? Both girls brought Allie the same type of candy, so who could say which girl’s candy did the job? Investigators found a piece of candy McMullen gave Allie, but no one tested it for poison. Why?

The jury deliberated for ten hours before returning a verdict of not guilty. Tona Dunlap was acquitted of murder on January 3, 1903.

In early August 1903, Tona announced she was writing a book that would tell the story of the case. She called it The Trial of Tona Dunlap as Told by Herself. If it was published, there are no references to it online.

Two years after the case was closed, Mary Dunlap, Tona’s mother, attempted to kill herself twice. The first time she tried to drown herself. The second time, she lay down on the tracks in front of a Burlington Road train. The crew spotted her in time and pulled her off the tracks. Did her suicide attempts have anything to do with Allie’s death? No one followed up to find out what was behind her suicide attempts.

Tona Dunlap moved to Quincy, Illinois, and married Jackson Thompson, a conductor on the Burlington Road, in June 1909.

We can only suppose she lived happily ever after.
