New details are emerging about the sudden death of Presley Gerber, the 27-year-old son of supermodel Cindy Crawford and businessman Rande Gerber.

Gerber died on Sept. 20 while staying at a sober-living facility in Santa Monica, California.

Authorities are investigating the death as an apparent overdose, but officials have stressed that the final cause and manner of death have not yet been determined.

The Los Angeles County Department of Medical Examiner confirmed that Gerber was pronounced dead by responding paramedics at 9:45 a.m.

A deputy medical examiner performed an examination the following day.

The cause and manner of death were then listed as deferred, meaning additional testing or studies are required before officials can make a final determination.

The department said deferred cases can take several months to resolve.

Because the investigation remains active, officials have not disclosed what additional testing was ordered.

The Santa Monica Police Department is handling the law-enforcement investigation.

Police have said there is currently no indication of foul play.

But investigators are also looking into the possibility that Gerber suffered an overdose shortly before his death.

According to the Los Angeles Times, emergency dispatch records show that authorities received calls involving both a cardiac arrest and an overdose at Resolutions Living, the Santa Monica facility where Gerber had been staying.

Police arrived at the property at around 9:35 a.m.

Gerber was pronounced dead approximately 10 minutes later.

The Times also reported that he had checked into the facility only hours earlier, on Saturday night.

That timeline has become an important part of the investigation.

Law-enforcement sources told the Los Angeles Times that detectives are now trying to determine where the drugs connected to the suspected overdose came from.

The investigation remains in its early stages.

Gerber had spoken publicly for years about his struggles with addiction and mental health.

In interviews and social-media posts, he described periods of treatment, efforts to get sober and the emotional toll of his condition.

People close to the family told People that Crawford and Rande Gerber had spent years trying to help their son through therapy, rehabilitation programs, sober coaches and other forms of treatment.

Those sources said Presley had experienced periods of sobriety but that his struggles had intensified over the past year.

His sister, model Kaia Gerber, had also spoken publicly about her brother’s openness regarding addiction and mental health.

Family members described that openness as part of his effort to help others who were facing similar problems.

One of Gerber’s final public discussions of treatment involved ibogaine, a psychedelic substance sometimes used outside the United States in attempts to treat addiction.

In a social-media post earlier this year, he described undergoing an ibogaine treatment and expressed hope that it would help him move forward.

His death has also brought fresh attention to the facility where he was staying.

Resolutions Living operates as a sober-living residence rather than a traditional hospital-style treatment center.

The Los Angeles Times reported that the property is not regulated under the same state licensing system that applies to formal treatment facilities, a distinction that has renewed scrutiny of California’s sober-living industry.

More recent reporting has raised additional questions about the hours before Gerber entered the facility.

TMZ, citing unnamed sources, reported that staff may have been told Gerber was already under the influence before he arrived.

That claim has not been independently confirmed by authorities, and the facility has not publicly provided a detailed response addressing the allegation.

For now, the most important official fact remains unchanged:

There is still no final medical determination explaining exactly what killed Presley Gerber.

The Medical Examiner has completed an initial examination.

Toxicology and other testing are pending.

Police are investigating an apparent overdose.

And detectives are reportedly trying to identify the source of the substances involved.

The Gerber family has asked for privacy while they grieve.

In a statement released after his death, the family said they were devastated and requested space during what they described as an extremely painful time.

Friends and relatives have since rallied around Crawford, Rande and Kaia.

George and Amal Clooney, longtime friends of the family, were among those reportedly helping support them in the days after Presley’s death.

Gerber had built his own modeling career separate from his famous mother.

He appeared in major fashion campaigns and walked runways for well-known designers.

In 2018, he and his sister Kaia were both featured in a Calvin Klein Jeans campaign.

But in the final years of his life, Gerber became increasingly candid about a much more personal struggle.

He spoke about addiction.

He spoke about depression and anxiety.

And he repeatedly described his efforts to recover.

That makes the circumstances of his death especially painful.

He died inside a place intended to support sobriety.

Police are now trying to determine how the suspected drugs reached him.

And the final answer may not come for months.

Until toxicology and other testing are complete, any definitive claim about exactly what caused Presley Gerber’s death would be premature.

What is known is that a 27-year-old man who had publicly fought addiction for years died suddenly on the morning of Sept. 20.

And the investigation into how it happened is far from over.
