In a quiet corner of Wilmer, Alabama, a loving mother and her two children were slaughtered in their own home in one of the most horrific crimes the Mobile County community has ever witnessed. Now, the grieving husband of Lisa Fields has broken his silence in an explosive interview, revealing shocking new details about the man accused of the massacre — and the financial debt that may have triggered the unimaginable violence.

Nathan Fields, husband to 46-year-old Lisa and stepfather to her children, sat down with Daily Mail to speak publicly for the first time since the nightmare unfolded. His voice cracked with emotion as he described how William Graham Oliver, a man he once allowed into their home almost daily, allegedly wiped out his entire family over money owed to Lisa.

“He destroyed my world,” Nathan said, eyes filled with tears. “Bill was around all the time. I never thought he was dangerous — just a bit creepy. But now I know the truth. He owed Lisa money and that debt cost my wife, my stepdaughter, and my stepson their lives.”

The brutal slayings have sent shockwaves across America. Lisa Fields, her 17-year-old daughter Keziah Luker (who was eight months pregnant), and her 12-year-old son Thomas Cordelle Jr. were found bound with zip ties in separate rooms of their mobile home. The violence was savage: Lisa and Thomas were nearly decapitated by throat slashes, while Keziah was shot twice in the head. The unborn baby also perished, bringing the toll to four innocent lives.

The Day Everything Changed

On April 19, 2026, the Fields family home on Auble Moody Road became a scene of unimaginable horror. Neighbors noticed something was wrong when no one answered calls or came outside. The next morning, authorities discovered the bodies in a scene prosecutors described as one that “cries out” for the death penalty.

William Graham Oliver, 54, was arrested days later and charged with eight counts of capital murder. Prosecutors allege the killings occurred during a burglary, with Oliver knowing the family well. Bond has been denied, and the District Attorney’s office is seeking the death penalty.

For Nathan Fields, the arrest brought a twisted form of closure — but also reopened devastating wounds. In his first in-depth interview, he revealed the financial entanglement that may have pushed Oliver over the edge.

“Lisa had helped him out financially more than once,” Nathan explained. “She was kind-hearted like that. But he owed her a significant amount. I think that debt was eating at him. Instead of paying what he owed, he chose to take everything from us.”

Who Was William Graham Oliver?

To the outside world, Oliver appeared as a familiar face in the tight-knit Wilmer community. He had known the family for some time and visited their home frequently — sometimes daily — over the past year. Nathan Fields described him as someone who blended into their routine, someone they had no reason to fear.

“I never would have taken him as dangerous,” Nathan said, his voice heavy with regret. “I would’ve just taken him as the creepy type. What he looked like to me after the arrest was someone that the devil used up and left drained and nothing.”

Oliver’s criminal history stretches back decades, according to court records. Prosecutors highlighted his past when arguing successfully against bond, painting him as a dangerous individual capable of extreme violence. Yet to the Fields family, he was simply “Bill” — a man who had somehow become part of their daily lives.

Lisa Fields, friends and family say, was a generous woman who often helped those around her. Whether it was lending money, offering support, or opening her home, she had a big heart. That generosity, tragically, may have placed her family directly in harm’s way.

A Family Torn Apart: Remembering the Victims

Lisa Fields was the heart of her household — a devoted mother who worked hard to provide for her children. At 46, she was looking forward to becoming a grandmother when Keziah gave birth. That joy was stolen in the most horrific way imaginable.

Keziah Luker, 17 and eight months pregnant, had her whole life ahead of her. Described by relatives as vibrant and full of promise, she was preparing for motherhood when her life was cut short by two gunshots to the head. Her unborn child — a baby the family was excitedly awaiting — died with her.

Young Thomas “TJ” Cordelle Jr., just 12 years old, was a typical boy full of energy and innocence. His life ended in terrifying violence, bound and nearly decapitated in his own bedroom.

The triple (technically quadruple) murder has devastated the extended family. Lisa’s sister, Shannon Corry, previously suggested in interviews that the debt Oliver allegedly owed Lisa could have been a key motive. Now, Nathan Fields is adding his voice to that theory, painting a picture of mounting pressure over unpaid money that may have led to explosive rage.

Nathan Fields Speaks Out: ‘I’ve Played Every Scenario in My Head’

In his emotional sit-down, Nathan Fields held nothing back. He described the surreal pain of learning the identity of the suspect — a man who had sat in their living room, shared meals, and been welcomed into their lives.

“I’ve played every scenario through my head,” he said. “Now that I know for a fact who it was, I can imagine how it happened. He came over that night looking for something — probably money or items to steal to settle his debt. When things went wrong, he chose murder over mercy.”

Nathan revealed that Oliver’s visits had become so routine that no one questioned his presence. That familiarity, he now believes, gave the alleged killer the perfect opportunity to strike.

The grieving husband and stepfather also spoke about the unbearable emptiness left behind. “The house is so quiet now. No laughter from the kids, no voice from Lisa calling everyone for dinner. He didn’t just kill three people — he destroyed an entire family’s future.”

Inside the Investigation: Burglary Gone Horrifically Wrong?

According to authorities, Oliver was inside the home on the evening of April 19. The house was later found ransacked, supporting the theory that the killings happened during an attempted burglary or robbery tied to the financial dispute.

All victims were bound with zip ties and killed in separate rooms — a detail prosecutors say demonstrates premeditation and extreme cruelty. The DA’s office has made it clear they will push for the ultimate punishment, calling the facts of the case particularly heinous.

Oliver has pleaded not guilty, but the evidence against him is described as strong and circumstantial. His lengthy criminal record has only strengthened the case for keeping him behind bars without bond.

The Community’s Shock and Outpouring of Support

Wilmer, a small community outside Mobile, has rallied around the surviving family members. Vigils, fundraisers, and funeral services have drawn hundreds, with many expressing disbelief that such brutality could happen in their backyard.

Neighbors who once saw Oliver as harmless are now haunted by his regular presence in the area. Some have come forward with stories of uneasy interactions, while others admit they never suspected the depths of his alleged capacity for violence.

Churches and local organizations have stepped up to support Nathan Fields and the extended family, providing counseling, financial assistance, and prayers as they navigate unimaginable grief.

A Husband’s Plea for Justice

As the case moves toward trial, Nathan Fields says his focus is on ensuring justice for Lisa, Keziah, Thomas, and the unborn child. He hopes Oliver receives the death penalty and wants the full truth about the debt and motive to come out in court.

“I want the world to know who my family really was,” he said. “They were good people. Kind people. They didn’t deserve this. No one does.”

He also issued a broader warning: “Be careful who you let into your home. Be careful who you help. Sometimes kindness can be repaid with evil.”

The Bigger Picture: Debt, Desperation, and Deadly Consequences

While investigators have not officially confirmed the debt as the primary motive, multiple family members have pointed to it as a likely trigger. Lisa’s willingness to lend money, combined with Oliver’s alleged financial troubles and criminal background, may have created a perfect storm of resentment and desperation.

Legal experts following the case note that capital murder charges during the commission of a burglary or robbery often carry the strongest path to the death penalty in Alabama. With four victims and the particularly brutal nature of the killings, this case stands out even in a state accustomed to tough crime prosecutions.

Looking Ahead: A Family’s Long Road to Healing

For Nathan Fields, the fight for justice is only beginning. While he finds some solace in knowing the alleged killer is behind bars, the pain of losing his wife and stepchildren will never fully disappear.

In the days and months ahead, as court proceedings unfold, he hopes sharing his story will honor the memory of his loved ones and perhaps prevent similar tragedies in other families.

Lisa Fields, Keziah Luker, and Thomas Cordelle Jr. were more than victims — they were a mother, a soon-to-be mom, and a bright young boy whose lives were stolen in a moment of alleged greed and rage.

As William Graham Oliver sits in jail awaiting trial, Nathan Fields continues to mourn, to remember, and to demand answers. The debt that may have sparked this nightmare remains a central question — one that a jury will eventually help resolve.

For now, a devastated husband is left picking up the pieces of a shattered life, determined to ensure his family’s story is told and their killers held accountable.

The quiet streets of Wilmer may never feel the same again. A single unpaid debt, if proven as the catalyst, serves as a chilling reminder of how quickly financial pressure can turn deadly — and how fragile the line between acquaintance and monster can be.
