How investigators build a criminal case from drug overdose deaths like Hayden Panettiere’s

The death of Hayden Panettiere last month is now the subject of a federal investigation into whether the actress obtained illicit and possibly counterfeit drugs from a dealer in Southern California, a source familiar with the investigation told CNN.

But building a criminal case from her accidental overdose death will be an uphill challenge for investigators.

Tens of thousands of people die from drug overdose deaths every year, but only a few hundred per year lead to criminal charges. Some celebrity deaths in recent years, notably those of “Friends” actor Matthew Perry and rapper Mac Miller , have led to charges. Others, like the death of the musician Prince , did not.

“These are just really difficult cases, regardless of if you’re a celebrity or if you’re just John Q. Public,” said Thaddeus Johnson, a former law enforcement official in Tennessee and senior fellow at the Council on Criminal Justice think tank.

The challenge for investigators lies in the gritty details. To make the case, they have to follow the trail of evidence, such as phone records, drugs and witnesses, to identify a dealer or supplier. Investigators also have to prove with toxicology, forensic pathology, and medical analysis that the specific drugs caused the victim’s death.

Why it’s important to prosecute celebrity drug deaths and the message it sends, according to legal experts

“Every case is different,” said CNN senior legal analyst Elie Honig, a former prosecutor. “Sometimes you can make a link. Sometimes you can’t.”

These investigations require significant resources, but overdose deaths are often not prioritized by police in the same way as a fatal shooting. Celebrity deaths may be an exception, though.

“It does seem that police are more attentive to and more invested in cases that get a lot of attention when it’s a well-known person who overdoses,” Honig said.

The challenges of bringing these cases are newly relevant as investigators dig into Panettiere’s death .

Panettiere, who wrote in a memoir of her struggles with drug and alcohol addiction, was found in cardiac arrest at an apartment in Greenville, South Carolina, on August 16. Medics responded to the scene but were unable to resuscitate her.

Dispatch audio obtained from Broadcastify.com references a possible overdose. The coroner’s office ruled Tuesday she died of toxic effects of fentanyl and other substances, and the manner of death was ruled an accident.

Last week, US Attorney General Todd Blanche said bringing criminal cases in overdose deaths is a “big emphasis” of the DEA and prosecutors around the country.

“There’s a federal statute that allows us to go after – assuming we can prove who the dealer is – to go after them and put them in prison for murder. And we do it in every district in this country,” he said.

“So when we can prove – and sometimes if somebody is an addict, it’s difficult to prove who they actually got the pill from – but in the cases where we know who the dealer was, and we can prove beyond a reasonable doubt that the person sold the death pill to the victim who then dies, that’s a federal crime and that’s something that we will readily prosecute as often as we can.”

While the US sees tens of thousands of overdose deaths every year, criminal charges stemming from an overdose death are rare.

There were about 79,384 drug overdose deaths in the US in 2024, according to CDC data . That was a sharp decline from the previous few years, when more than 100,000 people died of drug overdoses.

By comparison, a total of 1,340 people were sentenced for a federal drug trafficking offense involving a drug overdose between fiscal years 2019 to 2023, according to a 2025 report from the US Sentencing Commission . That works out to about 270 cases per year.

About 95% of the cases involved fentanyl, a synthetic fentanyl analog or heroin, the commission’s report found. Most of the people selling or using drugs did not know the exact drugs involved, the report states.

Just over half of the defendants were street level dealers, and the average sentence in cases involving an overdose was 149 months, or over 12 years, the report found.

Building a criminal case out of a drug overdose requires two key things: Evidence of the drug’s source, and evidence the drug caused death.

For the first part, investigators use phone records, bank records, witnesses and other evidence to try to work their way up the chain to identify the dealer or supplier. But that can be difficult in the underground drug economy, as counterfeit pills may come from the streets or even strangers on the internet.

“Sometimes you’re chasing a ghost,” Honig said. “Sometimes you just can’t figure out where the end user got the drugs from, and once the chain goes cold, that’s it.”

The second challenge is proving that the specific drugs caused the death. The National Association of Attorneys General calls this the “lynchpin” of the case, saying “causation raises perhaps the most difficult issues in proving these cases.”

The challenge is that addicts may take many different substances, or they may be in bad health generally. This all means that the toxicology report and the medical examiner’s review is paramount in an overdose death, and those take time and resources.

“These damn cases are just so damn difficult to prove,” Johnson said. “You have to prove somebody sold the drugs. You have to prove that the drugs they sold caused the particular death. Those are different things.”

Though criminal overdose cases are rare, a few high-profile deaths have resulted in charges.

On October 28, 2023, Perry , the “Friends” star, was found floating face down in his hot tub at his home in Pacific Palisades, California. The Los Angeles Medical Examiner’s Office listed the cause of death as “acute effects of ketamine” and subsequent drowning.

Five people later pleaded guilty to federal drug charges resulting from his death. The defendants were identified as a woman referred to by authorities as the “Ketamine Queen,” two doctors, Perry’s live-in personal assistant and a middle-man.

The evidence against Jasveen Singh, the so-called Ketamine Queen, included text messages, phone records and the discovery of drugs in her residence during a raid, according to federal prosecutors .

Similarly, the September 2018 death of rapper Mac Miller was determined to be an accidental overdose of fentanyl, cocaine and alcohol. Prosecutors later brought charges against men who allegedly provided the rapper counterfeit oxycodone pills containing fentanyl two days before the overdose. Two men pleaded guilty and were sentenced to nearly 12 years and 17.5 years in prison, respectively, per court records.

On the other hand, there were no criminal charges filed after the April 2016 death of Prince . Authorities said there was “no reliable evidence” of who supplied the counterfeit fentanyl-laced Vicodin pills that killed him or how he obtained them.

None of the medications found in Prince’s home was prescribed to him , according to court documents. Some bottles of opioid painkillers in his home were prescribed to an associate, and other medications were found in vitamin bottles and envelopes, search warrants showed.

In Panettiere’s case, after police responded to an emergency call when she was unresponsive, her boyfriend showed an officer a bag of her medications, according to a police report.

The coroner’s office report identified her cause of death as toxic effects of fentanyl, the synthetic opioid; 4-ANPP , a chemical used to make fentanyl; Alprazolam , a benzodiazepine commonly used to treat anxiety; Methocarbamol , a muscle relaxant; and Quetiapine , an antipsychotic drug.

Ultimately, the goal of bringing these cases is to try to crack down on organized crime and deter others from illegally distributing dangerous drugs.

“One community may be impacted by one dealer, but you take out a distribution center, you’ve maybe protected the whole West Coast or Southern California perhaps,” Johnson said. “(These cases) matter as far as in scale but also as a deterrence signal that you will be caught, you will be prosecuted, and you can no longer operate in ambiguity in these types of cases anymore.”

据一位熟悉调查的消息人士告诉 CNN，上个月海顿·潘妮蒂尔的死亡事件现在已成为联邦调查的对象，调查内容是这位女演员是否从南加州的一名毒贩那里获得了非法且可能是假冒的毒品。

但要从她的意外吸毒过量死亡中建立刑事案件，对调查人员来说将是一个艰巨的挑战。

每年有数万人死于药物过量，但每年只有几百人因此被提起刑事诉讼。近年来，一些名人的死亡，特别是《老友记》演员马修·佩里和说唱歌手麦克·米勒的死亡，都导致了刑事指控。而另一些名人的死亡，例如音乐家王子的死亡，则没有。

“无论你是名人还是普通民众，这些案件都非常棘手，”田纳西州前执法官员、刑事司法委员会智库高级研究员萨迪厄斯·约翰逊说道。

调查人员面临的挑战在于那些繁琐的细节。为了破案，他们必须追踪证据链，例如电话记录、毒品信息和证人证词，以锁定毒贩或供应商。调查人员还必须通过毒理学、法医病理学和医学分析来证明，特定的毒品是导致受害者死亡的原因。

法律专家认为，追究名人吸毒死亡案件的责任至关重要，而且此举传递的信息也十分重要。

“每个案件都不一样，”CNN高级法律分析师、前检察官埃利·霍尼格说。“有时候你能找到关联，有时候则找不到。”

这些调查需要耗费大量资源，但警方对吸毒过量致死案件的重视程度通常不及对致命枪击案。不过，名人死亡案件或许是个例外。

“如果吸毒过量者是知名人士，警方似乎会更加关注并投入更多精力处理这类备受关注的案件，”霍尼格说。

随着调查人员深入调查帕内蒂埃的死因，提起这些案件的挑战也变得尤为重要。

帕内蒂尔曾在回忆录中讲述了她与毒品和酒精成瘾作斗争的经历。8月16日，她在南卡罗来纳州格林维尔的一间公寓里被发现心脏骤停。医护人员赶到现场，但未能将她救活。

从Broadcastify.com网站获取的调度音频显示，她可能吸毒过量。验尸官办公室周二裁定，她死于芬太尼和其他物质的中毒，死亡方式被判定为意外。

上周，美国司法部长托德·布兰奇表示，对吸毒过量致死案件提起刑事诉讼是缉毒局和全国各地检察官的“重点工作”。

他说：“联邦法律允许我们追究毒贩的责任——前提是我们能证明是谁贩毒——并以谋杀罪将其绳之以法。我们在全国每个地区都这样做。”

“所以，当我们能够证明——有时如果有人是瘾君子，很难证明他们究竟是从谁那里得到的药丸——但在我们知道毒贩是谁，并且能够毫无合理怀疑地证明此人将致命药丸卖给了受害者，而受害者随后死亡的情况下，这就是联邦犯罪，我们会尽可能地提起诉讼。”

虽然美国每年有数万人死于吸毒过量，但因吸毒过量死亡而提起的刑事指控却很少见。

根据美国疾病控制与预防中心的数据，2024年美国约有79384人死于药物过量。与前几年相比，这一数字大幅下降，前几年死于药物过量的人数超过10万人。

相比之下，根据美国量刑委员会2025年的一份报告，在2019至2023财年期间，共有1340人因涉及吸毒过量的联邦毒品贩运罪被判刑。这相当于每年约270起案件。

委员会的报告发现，约95%的案件涉及芬太尼、合成芬太尼类似物或海洛因。报告指出，大多数贩卖或使用毒品的人并不清楚具体涉及哪些毒品。

报告发现，超过一半的被告是街头毒贩，涉及吸毒过量的案件平均刑期为 149 个月，即超过 12 年。

以吸毒过量致死案为由提起刑事诉讼，需要两个关键要素：毒品来源的证据，以及毒品导致死亡的证据。

首先，调查人员会利用电话记录、银行记录、证人证词和其他证据，试图追溯毒品交易链条，找出毒贩或供应商。但在地下毒品交易中，这可能非常困难，因为假药可能来自街头，甚至可能来自互联网上的陌生人。

“有时候你就像在追逐幽灵，”霍尼格说。“有时候你根本搞不清楚最终用户是从哪里弄到毒品的，一旦这条供应链断了，一切就都完了。”

第二个挑战是证明特定药物导致了死亡。全国总检察长协会称这是案件的“关键所在”，并表示“因果关系或许是此类案件中最难证明的问题”。

问题在于，吸毒者可能服用多种不同的毒品，或者他们本身健康状况就不好。这意味着，在过量用药致死案例中，毒理学报告和法医鉴定至关重要，而这些都需要时间和资源。

“这些该死的案子真是太难举证了，”约翰逊说。“你得证明有人贩卖了毒品。你还得证明他们贩卖的毒品导致了特定的死亡。这两者是两码事。”

虽然因吸毒过量致死的刑事案件很少见，但一些备受瞩目的死亡案例还是导致了指控。

2023年10月28日，《老友记》明星凯蒂·佩里被发现面朝下漂浮在位于加利福尼亚州太平洋帕利塞德的家中热水浴缸中。洛杉矶法医办公室将死因列为“氯胺酮急性反应”及其导致的溺水。

五人后来承认了与他死亡相关的联邦毒品指控。被告包括一名被当局称为“氯胺酮女王”的女子、两名医生、佩里的同居私人助理和一名中间人。

据联邦检察官称，针对被称为“氯胺酮女王”的贾斯文·辛格的证据包括短信、电话记录以及在突袭行动中在其住所发现的毒品。

“氯胺酮女王”因马修·佩里案被判刑，标志着毒品贩子问责制进入新时代。

同样，2018年9月说唱歌手麦克·米勒的死亡被认定为意外服用过量芬太尼、可卡因和酒精所致。检察官随后对涉嫌在麦克·米勒服药过量两天前向其提供含有芬太尼的假冒羟考酮药片的男子提起诉讼。根据法庭记录，两名男子认罪，分别被判处近12年和17.5年监禁。

另一方面，在2016年4月Prince去世后，并没有提起任何刑事指控。当局表示，没有“可靠证据”表明是谁提供了导致他死亡的掺有芬太尼的假冒维可丁药片，或者他是如何获得这些药片的。

法庭文件显示，在普林斯家中发现的所有药物均非其本人处方。搜查令显示，他家中的一些阿片类止痛药是开给一位熟人的处方药，其他药物则装在维生素瓶和信封里。

据警方报告，在帕内蒂埃的案件中，警方接到紧急电话称她失去反应后赶到现场，她的男友向一名警官出示了一袋她的药物。

验尸官办公室的报告确定她的死因是芬太尼（一种合成阿片类药物）、4-ANPP（一种用于制造芬太尼的化学物质）、阿普唑仑（一种常用于治疗焦虑的苯二氮卓类药物）、美索巴莫（一种肌肉松弛剂）和喹硫平（一种抗精神病药物）的毒性作用。

最终，提起这些诉讼的目的是为了打击有组织犯罪，并阻止其他人非法分销危险毒品。

约翰逊说：“一个社区可能只会受到一个经销商的影响，但如果你捣毁一个分销中心，或许就能保护整个西海岸甚至南加州。” “（这些案件）不仅规模巨大，而且具有威慑作用，它表明你终将被抓获，终将被起诉，在这类案件中，你再也不能含糊其辞了。”
