A Christmas Murder Plot: How a 911 Call Led Police to a Son Accused of Orchestrating His Parents’ Deaths

Christmas is usually a season of family gatherings, celebrations and new memories.

For Oscar and Dena Munoz, it was supposed to be exactly that.

The couple, who lived in Clovis, New Mexico, had recently celebrated their wedding anniversary in December 2025. They had just returned home from an out-of-town trip and were preparing to enjoy the holidays together.

Instead, their home became the scene of a crime that investigators would later describe as the result of a calculated murder plot allegedly involving someone they trusted most.

Their 19-year-old son, Darren Munoz.

Alongside his friend, Julio Zamora, Darren would eventually be charged in connection with the deaths of Oscar and Dena.

Both young men have pleaded not guilty, and the allegations remain to be decided at trial.

The investigation began shortly before 5:00 a.m. on December 15, 2025.

Police officers were dispatched to the Munoz residence after receiving a 911 call reporting what appeared to be a burglary in progress.

The caller was Darren Munoz.

When officers arrived, they immediately noticed something unusual.

The garage door stood open.

The front entrance was also unsecured.

Believing an intruder might still be inside, officers surrounded the home and repeatedly ordered anyone inside to come out with their hands visible.

For several tense moments, no one responded.

Eventually, Darren emerged.

He appeared calm and told officers he had just awakened.

When officers asked whether anyone else was inside, Darren replied that both of his parents were asleep in their bedroom.

The explanation seemed odd.

Police had responded to a burglary call, yet Darren claimed he had only recently woken up and knew nothing about what had happened.

Officers asked him to wake his parents.

Moments later, everything changed.

Instead of finding two sleeping homeowners, officers discovered a horrifying scene.

Oscar and Dena Munoz were lying in their bedroom with severe head injuries and large pools of blood surrounding them.

Radio traffic immediately shifted from a possible burglary to an emergency involving two apparent gunshot victims.

Additional officers and medical personnel rushed to the home.

As police secured the residence, Darren was escorted outside and placed in a patrol vehicle while investigators searched every room to determine whether a suspect remained inside.

No intruder was found.

The only surviving resident of the house was Darren.

At first, investigators treated him primarily as a witness.

He was transported to the police station and interviewed about the previous weekend, his parents’ recent trip and the events leading up to his 911 call.

Darren described spending much of the weekend alone while his parents were away.

He insisted they had returned home the previous day and claimed he had no idea what had happened overnight.

Investigators also asked about firearms.

Darren said he was not a gun enthusiast and claimed he had little knowledge of guns or ammunition.

According to investigators, however, evidence gathered during the investigation appeared to contradict those statements.

Police later said they recovered messages, photographs and videos allegedly showing Darren and his friend Julio Zamora discussing firearms, handling weapons and exchanging information about rifles, pistols and ammunition.

One message reportedly referenced an AR-style rifle, a Glock pistol and a so-called “ghost Glock.”

As the investigation progressed, detectives obtained search warrants.

Darren’s clothing was collected for forensic testing.

Investigators photographed him, obtained DNA samples and processed his clothing as potential evidence connected to the crime scene.

Meanwhile, detectives began interviewing people who knew Darren and Julio.

Those conversations dramatically changed the direction of the investigation.

One of Darren’s girlfriends described hearing discussions weeks earlier about wanting Darren’s parents “gone.”

According to her account, Julio allegedly offered to carry out the killings in exchange for money.

Another young woman described overhearing Darren discuss multiple ways his father could die.

She recalled Darren allegedly talking about sabotaging his father’s truck brakes so he would crash.

She also remembered conversations suggesting someone could quietly enter the home while Oscar slept.

At the time, she believed Darren was joking.

She described him as someone who often made outrageous comments without acting on them.

After learning of the murders, those conversations suddenly appeared much more serious.

While detectives continued gathering witness statements, officers located Julio Zamora and brought him in for questioning.

Initially, Julio denied knowing why he had been arrested.

He admitted being friends with Darren but claimed he knew nothing about the murders.

Detectives quickly challenged that account.

They told Julio they had already spoken with numerous witnesses and executed multiple search warrants.

According to investigators, they already understood much of what had happened.

Julio eventually acknowledged discussions about Darren wanting his parents dead.

He told detectives Darren had approached him approximately two months earlier, asking him to kill Oscar and Dena.

Julio claimed Darren offered him several hundred thousand dollars.

Investigators questioned how a 19-year-old earning only a modest income could possibly make such a payment.

Julio said he never believed the money was realistic and insisted he refused the proposal.

According to Julio, Darren continued discussing different plans.

One idea allegedly involved making the murders look like a robbery.

The plan, investigators said, was to enter through the garage, shoot the victims, steal property and create the appearance that burglars had broken into the home.

Detectives pressed Julio about what happened on the morning of the killings.

At first, he minimized his involvement.

Then his story changed.

Julio admitted entering the garage.

He said he remained inside for several minutes, struggling with what to do.

According to his statement, he held the gun to his own head while debating whether to go through with the crime.

He claimed he wanted to leave.

Instead, he ultimately admitted carrying out the shootings.

Julio told detectives he immediately regretted what he had done.

He said he felt overwhelming guilt and later thought about taking his own life.

Investigators asked whether the firearm recovered during the investigation was the weapon used in the murders.

Julio answered yes.

He also alleged that Darren wanted the gun returned afterward.

According to Julio, there had never been a detailed escape plan.

After the shootings, he said he simply ran away.

During questioning, Julio also claimed he had been afraid of Darren.

He alleged Darren threatened to kill him if he refused to participate.

Investigators questioned whether another individual named Vincent had played any role.

Julio denied knowing of any direct involvement beyond conversations about the plan.

Throughout the investigation, detectives built a theory very different from the burglary Darren initially reported.

Rather than an unknown intruder breaking into the home, prosecutors alleged the burglary story had been created to conceal a carefully planned double homicide.

According to investigators, the open garage door, Darren’s 911 call and the circumstances surrounding the discovery of the bodies were all consistent with an effort to stage the crime scene.

The witness interviews became central to that theory.

Multiple people described hearing Darren discuss killing his parents before the murders occurred.

Several also recalled conversations involving Julio and possible payment for carrying out the crime.

Prosecutors later alleged that Darren solicited someone else to commit the killings while helping create the circumstances that allowed the attack to happen.

The criminal charges reflected those allegations.

Darren Munoz was charged with two counts of first-degree murder, conspiracy to commit murder and solicitation of murder.

Julio Zamora was charged with two counts of first-degree murder and conspiracy to commit murder.

Both defendants have entered pleas of not guilty.

As a result, prosecutors will ultimately bear the burden of proving every element of the charges beyond a reasonable doubt.

Defense attorneys will have the opportunity to challenge the witness testimony, the interrogation statements, forensic evidence and investigators’ interpretation of the events leading to Oscar and Dena Munoz’s deaths.

The case remains pending.

Julio’s trial is currently scheduled for June 2027, while Darren’s trial is expected to begin in January 2027.

Until those proceedings conclude, the allegations presented by investigators remain allegations rather than established facts.

For the Munoz family, however, the tragedy cannot be undone.

What began as an ordinary December morning ended with two parents dead inside the home they believed was safe.

The son who called 911 asking police to respond soon became one of the central figures in the homicide investigation.

Investigators believe the burglary report was never what it appeared to be.

Instead, they allege it was the final act of a murder plot that had been discussed weeks before Christmas.

Whether prosecutors can prove that theory to a jury remains one of the central questions the upcoming trials will answer.

Until then, the case stands as one of the most disturbing family homicide investigations to emerge from New Mexico in recent years—a case where the first call for help may have been only the beginning of a much darker story.
