A new detail has emerged in the investigation surrounding Presley Gerber’s death: people close to the 27-year-old say a doctor had been giving him ketamine even though he had previously struggled with the substance.

The claim has added another layer of uncertainty to the final chapter of Gerber’s life as authorities continue trying to determine what was in his system when he died at a rehabilitation facility.

Gerber, the son of Cindy Crawford and Rande Gerber, died on Sunday while receiving treatment. His death is believed to have involved an overdose, although the official cause has not yet been determined.

An autopsy has been completed, but investigators are still awaiting the results needed to establish exactly what happened.

Friends Say Ketamine Had Been a Problem Before

According to people who were in regular contact with Gerber and had direct knowledge of his situation, a doctor had been prescribing him ketamine despite being aware of his history of drug addiction.

Those close to Gerber said ketamine had already been a recurring problem for him.

Some of his friends are now angry that the drug was prescribed at all, given what they understood about his previous struggles.

The frustration is significant because ketamine has legitimate medical uses and has increasingly been used in certain treatment settings, including for depression and, in some cases, addiction-related care.

However, treating drug addiction is not an FDA-approved use of ketamine.

The central question now is not simply whether Gerber had access to ketamine through a medical professional, but whether the drug played any role in his death.

At this stage, that has not been established.

The substances found in Gerber’s system remain unknown pending toxicology results.

Gerber Had Talked About Ketamine With Friends

The people close to Gerber said his difficulties with ketamine were not hidden from those around him.

Before his death, he had reportedly spoken to friends about problems involving the drug.

That history is now receiving more scrutiny because Gerber died while inside a rehabilitation facility, where he was supposed to be receiving treatment for addiction.

Friends familiar with his situation believe the decision to prescribe ketamine deserves closer examination.

Some have gone further, arguing that the doctor who supplied it should face legal consequences.

Whether authorities will take any action against the physician remains unclear.

Investigators have not announced that ketamine caused Gerber’s death, nor have they publicly identified the doctor who allegedly prescribed it.

The focus remains on reconstructing Gerber’s final hours and determining what substances he may have taken before he died.

Witnesses Said He Appeared Under the Influence

People who had contact with Gerber shortly before his death said he appeared to be under the influence while at the rehabilitation center.

That observation has become another important part of the developing timeline.

Police are investigating where any drugs he may have taken came from.

Authorities have also interviewed other patients at the rehabilitation facility as part of their effort to understand what happened.

Those interviews could help investigators determine whether Gerber obtained substances inside the center, arrived with them, received them through medical treatment or gained access through another source.

For now, the origin of the suspected drugs remains unresolved.

The pending toxicology findings are expected to be critical because they could establish whether ketamine was present in Gerber’s body and whether any other substances were involved.

A Complicated Relationship With Treatment

Gerber’s reported use of ketamine was not the only unconventional approach he had explored while trying to address addiction.

In the months before his death, he had also been experimenting with alternative treatments, including ibogaine.

Ibogaine is a psychoactive substance that some people believe can help individuals struggling with addiction by altering neurological pathways.

Gerber’s willingness to pursue such treatment suggests that he had been actively searching for ways to overcome the problems that had followed him.

That search now adds a tragic dimension to the investigation.

He was not simply using substances recreationally while avoiding treatment. He had been moving through different recovery options, including medical and alternative approaches, while attempting to address addiction.

The fact that he ultimately died inside a rehab facility makes the circumstances especially difficult for those close to him.

Ketamine’s Role Remains Unknown

The new information about Gerber’s doctor has naturally drawn comparisons to other high-profile cases involving ketamine.

One of the most notable is the death of actor Matthew Perry, who had received ketamine treatment for depression and anxiety after years of struggling with addiction.

Perry later obtained ketamine through additional sources, including Jasveen Sangha, who became known publicly as the “Ketamine Queen” and was sentenced to 15 years in prison for her role in his death.

Gerber’s case, however, remains at a much earlier stage.

There is currently no determination that ketamine caused or contributed to his death.

There is also no public evidence that he obtained it illegally from outside sources.

The comparison instead highlights the broader concern surrounding ketamine use among people with complex histories involving addiction.

In Gerber’s situation, investigators first need to determine what was actually in his system.

Only then can authorities begin to understand whether any prescribed medication, illicit substance or combination of drugs played a role.

Police Continue Examining the Final Hours

Gerber’s death has already prompted questions about what occurred inside the rehabilitation center during the hours before he was found unresponsive.

Investigators are examining his condition, his access to substances and the people who interacted with him shortly before his death.

The fact that other patients have been interviewed suggests police are trying to build a detailed picture of the environment inside the facility.

Those accounts may be especially important if toxicology results show the presence of drugs that Gerber was not supposed to have.

At the same time, if ketamine is found in his system, investigators would still need to establish whether it was administered as part of legitimate medical treatment and whether it contributed to the fatal event.

For Gerber’s friends, the concern is already more personal.

They say he had struggled with ketamine before and believe that history should have influenced how his treatment was handled.

The Autopsy Is Complete, but Answers Are Still Pending

Gerber’s autopsy has now been completed, but the findings have not yet provided a final public explanation for his death.

That means the most important questions remain open.

What drugs were in his body?

Where did they come from?

Did ketamine play any role?

And what happened inside the rehabilitation facility during his final hours?

Until the toxicology results are returned, those questions cannot be answered with certainty.

What is known is that Gerber had been actively seeking help for addiction, had explored multiple treatment approaches and had reportedly discussed his difficulties with ketamine with people close to him.

Now, the revelation that a doctor may have been prescribing him the same drug has become one of the most closely watched details in the investigation.

Gerber entered treatment searching for a way forward.

The investigation into his death is now focused on understanding whether one of the substances connected to that search may also have been present in his final hours.
