The Chilling Case Zachary Davis: He Murdered His Mother with a Sledgehammer And Tried To Burn His Brother Alive



On a quiet night in Hendersonville, Tennessee, the unthinkable happened

Zachary Davis, just 15,  bludgeoned his mother, Melanie Davis, to death with a sledgehammer as she slept. 

What followed was a chilling series of events that shocked the local community and captured global attention. 

Zachary’s actions left many questioning how such a calm young boy could commit such a heinous act.

Background

Before his father's death, Zachary Davis was known as a calm and cheerful boy.

When Zachary was 9, his father passed away from amyotrophic lateral sclerosis (ALS). 

This left him, his mother Melanie, and his older brother Josh to navigate life on their own.

The death of his father deeply affected Zachary, and he was soon diagnosed with depression. 

Despite Zachary's evident mental struggles, his mother chose to relocate the family to a new city, hoping for a fresh start.

However, the move seemed to push Zachary further into isolation.

His paternal grandmother, Gail Cron, noted that Melanie had cut off ties with her after the move.

This left Zachary without the support he desperately needed at the time.

As the years passed, Zachary's behavior became increasingly concerning. 

His teachers, neighbors, and even his mother noticed something was wrong.

Sadly, no substantial action was taken to address his deteriorating mental health. 

Gail Cron believed that with appropriate mental health treatment, the tragic events of 2012 could have been prevented.

The Night of Horror

On August 10, 2012, Zachary Davis carried out a heinous crime that he had meticulously planned.

After dinner with his mother and brother, Zachary waited for everyone to fall asleep in their home in Hendersonville, Tennessee. 

Around 11 p.m., he entered his mother's room, where she lay asleep, defenseless. 

Armed with a sledgehammer, he struck her head repeatedly—more than a dozen times—to ensure she was dead. 

In a later interview, Zachary admitted that he hit her with such force because he didn’t want to miss and wanted to make sure she wouldn’t survive.

After killing his mother, Zachary calmly went about the next phase of his plan. 

He set the house on fire in an effort to kill his older brother Josh, who was asleep at the time. 

After starting the fire, Zachary left, leaving his brother to die in the burning house. 

Fortunately, the sound of the smoke alarm woke Josh, and he managed to escape the blaze unharmed. 

After Josh had escaped, he called 911 for help, and soon, the authorities arrived at the scene. 

They discovered their mother dead in the fire, and initial investigations quickly pointed to Zachary.

However, Zachary was nowhere to be found as he had left the house after the fire began.

A Chilling Confession

The following morning, an officer spotted Zachary walking along Nichols Lane with a backpack and a satchel. 

He was quickly detained and brought in for questioning. 

Inside his bag, officers discovered items such as a pocket knife, a lighter, and a set of keys. 

Most disturbingly, they found a handwritten confession from the night of the murder.

In the confession, Zachary detailed how he had killed his mother and expressed no remorse for his actions. 

He wrote, “I didn’t feel anything when I killed her. My only true regret was that I didn’t give her a faster death. I didn’t want her to suffer.” 

He also claimed in the journal that he had been planning to kill his brother Josh ever since Josh had allegedly raped him.

When questioned by detectives, Zachary maintained his calm demeanor. 

He admitted to the murder and explained that he used the sledgehammer because it gave him the highest chance of success. 

His flat, monotone responses left investigators and the public stunned. 

When asked if he loved his mother, Zachary replied, “somewhat.” 

He went on to state that if he could go back in time, he would have killed his brother as well.

The Trial and Mental Health Debate

Zachary Davis' trial drew widespread attention.

This was due to the graphic nature of the crime and the complex issues surrounding his mental state. 

During the trial, his defense team argued that Zachary’s severe mental health issues played a significant role in the murder. 

His attorney, Randy Lucas, argued that Zachary was also a victim in this tragedy.

He pointed out that everyone in Zachary’s life had failed to intervene in a meaningful way. 

The defense maintained that his mental illness had made it impossible for him to truly comprehend the gravity of his actions.

However, the prosecution presented a different narrative. 

They argued that despite Zachary’s mental health struggles, he was fully aware of what he was doing. 

District Attorney Ray Whitley described the murder as one of the most horrific crimes he had ever seen. 

He believed that Zachary had premeditated the attack. 

The court heard evidence that Zachary had been reading Stephen King’s novel “Misery” and had been interested in serial killers and torture devices. 

During the trial, several mental health experts testified.

While they disagreed on the exact diagnosis, they all agreed on one thing—Zachary knew right from wrong. 

The prosecution further highlighted Zachary’s lack of remorse.

They pointed out that he had laughed during the murder and had even joked about it afterward.

A Life Behind Bars

The jury deliberated for three hours before finding Zachary guilty of first-degree murder, attempted murder, and aggravated arson.

At the age of 17, Zachary Davis was sentenced to life in prison. 

Under Tennessee law, this meant he would be eligible for parole after serving 51 years. 

In addition to the life sentence, he received 20 years for attempted murder and 20 years for aggravated arson. 

The judge ordered that these sentences be served consecutively, ensuring that Zachary would spend at least 71 years behind bars.

Despite his young age, the judge saw no reason for leniency. 

Judge Dee David Gay, who presided over the trial, watched Zachary’s interview on the Dr. Phil show, where the teen detailed the murder. 

While some viewers saw a lost, troubled boy, the judge saw something else entirely: a young man who had embraced evil.

During sentencing, Judge Gay expressed his frustration with Zachary’s lack of remorse.

He said, “The thing that bothers me is that you have shown no regrets, no remorse, in murdering your own mother at age 15.” 

The judge emphasized that Zachary’s actions were a result of him “going to the dark side” and becoming consumed by evil.

Zachary’s defense team requested that he be placed in a special needs facility due to his age and mental health issues. 

The judge agreed to this request.

As a result, Zachary was remanded to the Louis DeBerry Special Needs Facility in Nashville, where he would serve his sentence.

The case of Zachary Davis raises many unsettling questions. 

Was this a crime born out of untreated mental illness, or was it the calculated act of a young man who had fully embraced darkness? 

Could this tragedy have been prevented if Zachary had received proper mental health care earlier in his life? 

While the legal system has rendered its verdict, the debate over what drove Zachary to commit such a brutal act will likely continue for years to come.

For the Davis family, there are no winners in this story. 

A mother is dead, a brother’s life is forever altered, and a young man will spend the rest of his life behind bars.

In another horror case, a man murdered his girlfriend and her entire family after being rejected.
