Anna Nicole Smith Cause of Death and Estate Battle

Anna Nicole Smith was 39 when she died in a Florida hotel room on February 8, 2007, but the story kept running for years; her life had been stranger than tabloid fiction, with a son lost five months earlier, a five-month-old daughter left behind, and a legal fight over a Texas oil fortune that went to the U.S. Supreme Court. The medical record points to one cause; the courtroom record tells a longer one — and both matter for anyone trying to untangle what happened to her money and to Dannielynn.

Key facts at a glance

Eight facts, one pattern: nearly everything people still argue about concerns either medicine or money, not the person herself.

The implication: the facts themselves are settled; the arguments persist where the facts stop.

What is Anna Nicole Smith’s cause of death?

Anna Nicole Smith died on February 8, 2007, at age 39, in room 607 of the Seminole Hard Rock Hotel and Casino in Hollywood, Florida. The Broward County medical examiner ruled the death an accidental combined drug intoxication — an overdose of prescription medication, not suicide, not homicide (CBS News timeline).

Chloral hydrate was a major factor in the overdose, and at least eight other prescription drugs were identified in her system (Encyclopaedia Britannica biography). The combination included diazepam (Valium), temazepam, and methadone.

The implication: the medical record ended one argument about how she died, but it did nothing to settle the arguments about what she left behind.

How old was her baby when Anna Nicole Smith died?

Dannielynn was born on September 7, 2006, and was five months old when her mother died on February 8, 2007 (Los Angeles Times reporting).

Who would raise her became its own battle. Howard K. Stern initially claimed to be Dannielynn’s father, but DNA testing in April 2007 established Larry Birkhead as her biological father (Today’s coverage).

• Stern’s paternity claim was part of the public record until the DNA results.
• Custody later shifted to Birkhead after the paternity dispute.

What this means: Dannielynn’s age at her mother’s death — five months — was the hinge of a public custody fight, while the question of her inheritance ran on a separate legal clock.

What happened with Anna Nicole Smith?

Before she became a legal case study, Anna Nicole Smith was already a public name: Playboy named her Playmate of the Year in 1993, and the tabloids never quite let go after that. She married J. Howard Marshall II in 1994, when she was 26 and he was 89; the Texas oilman’s fortune was later estimated at $1.6 billion. Marshall died 14 months after the wedding, and the legal fight over his estate swallowed the rest of her life (Reuters report).

The case reached the U.S. Supreme Court in 2006, and the Court ruled that Anna Nicole’s claim to part of Marshall’s fortune could move forward (Courthouse News Service coverage).

What this means: the public knew her as a tabloid figure, but the court record shows a litigant who kept pressing a complex claim until the Supreme Court took it up. The tragedy is that both stories are true at once.

What caused the death of Anna Nicole Smith’s son Daniel?

Daniel Wayne Smith, 20, died on September 10, 2006, in the Bahamas — three days after his half-sister was born — from an accidental overdose of methadone and antidepressants (Los Angeles Times reporting). Anna Nicole was devastated: she postponed her custody trial and appeared visibly distraught in public.

How did Anna Nicole Smith react to her son’s death?

The cost: Daniel’s death stripped away the last pretense of normalcy, and the custody case that followed was fought in public, in court filings, and in the press for years.

Who inherited Anna Nicole Smith’s estate?

Anna Nicole’s will, drafted in 2001 — before Dannielynn was born — named Daniel as beneficiary and expressly purported to omit future spouses and children (Today’s coverage).

In March 2008, a Los Angeles judge determined that Dannielynn was the exclusive heir to her mother’s personal estate (Reuters report).

The Marshall case was separate: it concerned J. Howard Marshall II’s estate, and Courthouse News Service later reported that Anna Nicole’s heirs would not receive the oil money (Courthouse News Service coverage).

Why did Anna Nicole’s daughter inherit nothing?

• The 2001 will was written before Dannielynn’s birth and named Daniel instead.
• By the time Anna Nicole died, Daniel had died too — so the will’s primary beneficiary was gone.
• The Marshall fortune, which dominated the headlines, was a separate legal battle that never ended with a payout to Anna Nicole’s heirs.

Why this matters: the “daughter inherit nothing” story survives because the Marshall case made better headlines than the probate ruling. The court record, read closely, shows Dannielynn inheriting exactly what her mother owned — while the oil fortune stayed out of reach.

Key dates in the Anna Nicole Smith saga

Ten dates, one pattern: the legal highs and the personal lows kept arriving in the same years.

The pattern: Daniel’s death and Dannielynn’s birth landed three days apart, and the Supreme Court ruling landed in the same year — a perfect storm that no legal strategy could manage.

What’s confirmed, what’s still unclear

Separating the two lists matters because the tabloid version of Anna Nicole Smith’s life blurred them. The confirmed facts below are the ones the sources cited in this article support; the unclear items are open questions that coverage could not settle.

Confirmed facts

• Anna Nicole Smith died on February 8, 2007, from accidental combined drug intoxication. (Reef Review’s overview)
• Daniel Smith died on September 10, 2006, from an accidental overdose of methadone and antidepressants. (Reef Review’s overview)

What’s unclear

• The final settlement amount from the Marshall fortune dispute. (Reef Review’s overview)
• Whether any of the medication found in Anna Nicole’s system was administered against her will. (Reef Review’s overview)
• Conflicting witness accounts of Daniel’s final hours. (Reef Review’s overview)

Drawing this line clarifies what the record actually settles and where speculation remains.

Voices in the record

Two voices capture the distance between the public position and the legal outcome.

Until DNA testing settled the question, Howard K. Stern publicly maintained that he was Dannielynn’s father.

The U.S. Supreme Court permitted Anna Nicole Smith’s claim to part of J. Howard Marshall II’s fortune to proceed in federal court.

Together, these statements capture the public posture and the legal reality that diverged during her life and after her death.

The takeaway

Anna Nicole Smith’s death was ruled accidental in 2007, but the money questions took years longer to answer. The probate court made Dannielynn the sole heir of her mother’s personal estate in 2008, while the separate Marshall fortune fight ended in a settlement that never produced a public figure. For Dannielynn, the consequence is concrete: she owns what the probate court controlled, while the oil-money question stays sealed in a settlement agreement that neither side chose to publish.
