Who Poisoned Ross Ashbaugh in Maynard Iowa?

By the time they dug Ross Ashbaugh out of the ground for the third time, people around Maynard had stopped asking whether he’d been poisoned.

They were asking who had done it.

The Ashbaugh farm sat outside Maynard, Iowa, surrounded by fields that rolled flat into the summer heat. Neighbors noticed everything. Who came by? Who stayed too long? Which marriages looked strained at church on Sunday morning.

Ross Ashbaugh was 44 and built like a man who’d spent his life outdoors. He farmed, raised livestock, and kept the operation running through the endless cycle of planting, feeding, fixing, and harvesting. He and his wife, Effie, were raising two children, Lucile and Edward. By most accounts, Ross wasn’t flashy or loud. Just another hardworking Iowa farmer trying to get by.

Arthur Cahoe had been around the farm for four years.

He was 38, hired help, and close enough to the family that people didn’t think twice about seeing him there. He worked alongside Ross during the day and spent evenings in the house. Over time, neighbors noticed the way Cahoe and Effie acted around each other.

Nothing obvious. Just little things.

Long conversations. Looks that lasted a second too long. The details people stored away without mentioning until later.

Then Ross got sick.

It started on July 6, 1921. At first, it didn’t seem unusual. Farmers got sick all the time. Bad water, spoiled food, exhaustion. Infections that spread before doctors could stop them.

Ross complained about a burning pain in his stomach. His mouth and throat hurt, and he couldn’t stop drinking water. He vomited repeatedly and grew weaker by the day.

The sickness dragged on for more than a week. Then, Ross seemed to improve. By July 11, he felt much better. Family members believed he might recover after all. The worst appeared behind him.

Effie brought him a cup of beef broth.

According to testimony repeated in newspapers across Iowa, Ross drank it and almost immediately got sicker. The pain came back. He vomited violently and struggled to breathe.

Doctors warned Effie that her husband was hanging by a thread. Ross had only “one chance in a thousand” of surviving. They warned her not to move him because even the strain of lifting him could kill him.

A few hours before he died, she moved him anyway.

Ross Ashbaugh died on July 15 after eight days of agony.

The scene afterward stuck in people’s minds almost more than the death itself.

Effie fainted when Ross died. Arthur Cahoe carried her upstairs, then stayed with her through the night while Ross’s body remained downstairs in the farmhouse.

By morning, the rumors had started.

People whispered that Effie and Cahoe had been involved for years. Some called it an affair. Others tried to soften it with phrases like “too friendly.” Either way, suspicion spread through Fayette County.

The gossip became impossible to separate from the death.

Not everyone believed it.

Ralph Winegar, the county agricultural agent and a longtime friend of the family, defended Effie. He described her as “an ideal type of American farm woman,” saying the case against her was fueled by gossip more than evidence.

Other people floated a different theory. Maybe Ross poisoned himself.

Winegar dismissed that, too.

Investigators weren’t convinced by either explanation.

Two months after Ross was buried, authorities ordered his body exhumed. On September 20, doctors removed his organs and shipped them to Iowa City for testing.

The results changed everything.

Tests found arsenic throughout Ross Ashbaugh’s body in amounts large enough to kill him. Investigators also claimed poison had been discovered on the farm itself.

In early October, a grand jury indicted Effie Ashbaugh and Arthur Cahoe for first-degree murder.

The case exploded across the Iowa newspapers.

Readers couldn’t get enough of it. A dying farmer. A wife accused of poisoning him. A hired man sleeping upstairs while the husband’s corpse lay downstairs. Every ugly detail fed the story.

Cahoe said little after his arrest. He denied involvement but offered one statement that followed him through the case.

“If Effie did it, she did it without my knowledge.”

Effie became the center of attention.

Reporters studied her every move. Jail attendants told newspapers she seemed strangely unemotional. Some called her “cold blooded” because she rarely cried or reacted visibly to the accusations.

Others saw something different.

A tired farm woman trapped inside a scandal she couldn’t escape.

When Effie finally took the stand, the courtroom packed with spectators. For three hours she answered questions about her marriage, Cahoe, Ross’s illness, and the rumors surrounding the farm.

Newspaper reporters expected a dramatic collapse.

It never came.

They described her as quiet, modest, and calm under pressure. She admitted to several “indiscreet actions” but refused to explain them. She denied poisoning her husband and insisted Cahoe had simply become a close family friend over the previous four years.

By the time the case reached the jury, nobody seemed certain what would happen.

The prosecution had arsenic and rumors of an affair. They had suspicious behavior and a dead man who suffered terribly before dying.

What they didn’t have was proof of who administered the poison.

The jury returned its verdict on December 10, 1921.

Not guilty.

Just like that, the state’s murder case collapsed. Charges against Arthur Cahoe were dropped soon afterward, and he walked free from the West Union jail in January.

Ross Ashbaugh was still dead. Arsenic had still been found in his body. But nobody was ever convicted of poisoning him.

Years later, people around Maynard still talked about the Ashbaugh farm. Some believed the case had been built entirely on gossip, jealousy, and the appearance of scandal. Others believed Ross Ashbaugh had been murdered slowly inside his own home while the people responsible sat beside his bed waiting for him to die.

The verdict ended the trial. It didn’t end the story.
