Who has authority to determine whether death was natural, accidental, suicidal, or homicidal? My understanding is that generally (and in broad strokes) it is the responsibility and authority of a jurisdiction's Coroner (a.k.a. Medical Examiner) to determine the cause and manner of any death not certified by an attending physician. Suppose someone is found dead after a fall. Suppose the Coroner, on reviewing the body and scene, finds nothing but deadly injuries consistent with the fall and the circumstances in which the body was found. Now, one of four scenarios is possible: The person died of natural causes and then fell (natural death) The person fell accidentally (accidental death) The person fell intentionally of their own volition (suicide) The person was caused by another to fall (homicide) Does the Coroner have the final say on cause of death? Or do any other offices have the right to investigate a death to look for evidence of homicide in opposition to a verdict of the Coroner? For example, Can police pursue an investigation independent and contrary to that of the Coroner? Does a District Attorney (when not the Coroner) have the means and/or authority to conduct an independent and contrary investigation?
Short Answers Does the Coroner have the final say on cause of death? No. The trial judge (or jury) has the final say. Can police pursue an investigation independent and contrary to that of the Coroner? Theoretically, yes. But I would expect that would happen only in unusual circumstances. Like, maybe an internal investigation. Standard procedure is for the prosecutor, police and medical examiner to work together to investigate crimes and prosecute criminals. Does a District Attorney (when not the Coroner) have the means and/or authority to conduct an independent and contrary investigation? Yes. But it's unusual. See answer to number 2. Or do any other offices have the right to investigate a death to look for evidence of homicide in opposition to a verdict of the Coroner? Same answer as #2 and #3. Explanation They work together on the same team The medical examiner is a state employee and usually works on the side of law enforcement. If a medical examiner were to report a cause of death that did not support evidence of a crime, that information would have to be made available to any potential defendant. In the hands of any competent attorney that should be sufficient basis to create reasonable doubt and achieve an acquittal. I doubt many prosecutors would ever consider hiring an outside examiner in this case except under highly unusual circumstances like an internal investigation as mentioned above. The defendant must create reasonable doubt In the alternative scenario, when evidence of a crime is supported by the M.E. report, it would be up to the defendant to produce reasonable doubt by cross-examination or producing expert testimony that contradicts the M.E.'s conclusion. This might or might not include hiring an independent third party forensic pathologist as an expert witness. Dr. Cyril Wecht is a famous one. All opinions are subject to error, disagreement and cross-examination All that said, the "cause of death" reported by the Coroner is just a medical opinion and is subject to error and disagreement like any other opinion. It's just that it's unlikely that disagreement would come from the side of law enforcement in most cases. For further reading, here is a link to the Coroner's Handbook. At the bottom of page 11, it acknowledges: Causes of death on the death certificate represent a medical opinion that might vary among individual medical-legal officers.
Criminal charges are filed and prosecuted by the government, on behalf of the public, and there is no requirement for approval or cooperation by the victim. As a policy matter, a DA may decide to not charge a person in case the victim is unwilling (though less so in cases of domestic violence), perhaps because of the widespread impression that the victim has to "press charges" (which indeed they would have to do in the case of private prosecution, which is no longer allowed in the US). The alleged victim's reddit exchanges on the topic are here. An uncooperative victim does not make a good witness, even if they are compelled to testify. The police statement that they cannot pursue an investigation should not be interpreted as a statement of law, it's probably a statement of policy and practicality.
With these facts, assuming Mr Y was charged with involuntary manslaughter (like in MA v. Carter) or aiding a suicide, based solely or almost solely on the messages, under which jurisdiction would he be charged? Applicable Law States have jurisdiction both over crimes that are committed in the state and over crimes that cause harm in a state. The classic law school example is a murder committed by shooting someone with a gun across a state line. Both the state where the gun is fired and the state where the person is shot have jurisdiction over the crime. Jurisdiction generally requires a purposeful act directed at someone or something in the state where the harm is suffered in most cases. But that isn't a hard and fast rule of constitutional law in other contexts, and there are few cases on point. I would consider this to be an open question. Certainly, however, the mere fact that the victim of a crime is transported to another state for medical treatment, where that victim then dies from causes relate to the crime, does not give the state where the death ultimately occurs in the hospital jurisdiction over the offense. Double Jeopardy Indeed, the constitutional protection against double jeopardy does not prohibit both states from independently convicting and punishing the same defendant for the same crime in this situation under the &quot;dual sovereignty&quot; doctrine. As background, the Colorado Supreme Court decided a dual sovereignty double jeopardy case today. Application To Facts (The application to the facts has been revised upon closer examination of them.) The line about &quot;Ms X, who is, at this point, still in Nevada,&quot; is confusing because she was in California before and isn't described as ever being in Nevada. I presume that &quot;still in California&quot; was really meant. Mr. Y could be charged (at least) in Nevada or New Jersey from which the continuing course of communications was sent (undue emphasis on the final communication is probably inappropriate), and Wyoming, to which the bulk of the communications were directed and where the bulk of the harm was suffered. California and Nebraska do not seem to be places to which the communications were really directed or where the greatest harm was suffered. Momentary presence in Nebraska air space is probably insufficient. There are also a set of statutes that specifically address crimes committed during an airplane flight (see also here) that has been discussed in other answers at this website. To the extent that this is treated as a homicide committed while in flight, 49 USC § 46506, might also allow for a federal criminal prosecution. I'm not sure that this is really a crime committed in flight, however, as it involved a course of conduct. A single email or a single moment of death doesn't really capture it. It is more analogous to a poisoning taking place in many doses over a period of time. Is Mr Y's speech in this case protected by the First Amendment? No. First Amendment considerations do apply to crimes involving communications between people that are not false, but if there is sufficient intent to cause suicide or other harm, the First Amendment yields to other considerations. The freedom of speech is not absolute. The exact place that the line is drawn is a matter of ongoing litigation. This specific issue is explored in depth in Clay Calvert, &quot;The First Amendment and Speech Urging Suicide: Lessons from the Case of Michelle Carter and the Need to Expand Brandenburg Application&quot; 94 Tulane Law Review 79 (November 2019). This article is responsive to that case of Commonwealth v. Carter, 115 N.E.3d 559 (Mass. 2019). The article explains in its introduction that: In February 2019, the Massachusetts Supreme Judicial Court in Commonwealth v. Carter' affirmed Michelle Carter's conviction for involuntary manslaughter as a youthful offender based on her urging Conrad Roy to commit suicide.' In doing so, the court rejected Carter's claim that her conviction violated her First Amendment' right of free speech. Specifically, it reasoned that Carter's words with Roy immediately before and while he died were &quot;integral to a course of criminal conduct and thus [did] not raise any constitutional problem.&quot; In brief, Massachusetts's high court concluded that Carter's speech caused Roy's death' and that the First Amendment provided her no refuge.'
This assumes there is a difference under the law between reckless and negligent homicide (which does not exist everywhere). In Washington state there is a distinction between 1st and 2nd degree manslaughter, per RCW 9A.32.060 and .070. What could be called reckless homicide is when (a) He or she recklessly causes the death of another person; or (b) He or she intentionally and unlawfully kills an unborn quick child by inflicting any injury upon the mother of such child. and 'negligent homicide' would be A person is guilty of manslaughter in the second degree when, with criminal negligence, he or she causes the death of another person. The distinction is laid out in RCW 9A.08.010, compare A person is reckless or acts recklessly when he or she knows of and disregards a substantial risk that a wrongful act may occur and his or her disregard of such substantial risk is a gross deviation from conduct that a reasonable person would exercise in the same situation. and A person is criminally negligent or acts with criminal negligence when he or she fails to be aware of a substantial risk that a wrongful act may occur and his or her failure to be aware of such substantial risk constitutes a gross deviation from the standard of care that a reasonable person would exercise in the same situation. However, it is important to know what "knows" means: (i) he or she is aware of a fact, facts, or circumstances or result described by a statute defining an offense; or (ii) he or she has information which would lead a reasonable person in the same situation to believe that facts exist which facts are described by a statute defining an offense. The fact that X has manufactured a nutty belief that killing a person doesn't lead to death does not override the fact that a reasonable person would know that stabbing a person in the heart will in fact kill them, and is murder. You could put that in contrast to the situation where he has a belief that stabbing a victim in the butt will cure him, and he is unaware that the victim's heart is freakishly in the wrong place, near his wallet – that would be negligence (being unaware). In general, you aren't given legal credit for having bizarre beliefs about how the universe works, unless it can be turned into an insanity defense.
I overdosed on an illegal drug and called an ambulance. I was honest and told them what I took. [emphasis added] You stated that you had possession, and had recently used a notable amount, of an illegal substance. That is reasonable cause (or "probable cause" in some jurisdictions) for a search, regardless of a warrant, and they do not need permission. For example, as FindLaw.com explains, in the USA. [p]olice may use firsthand information, or tips from an informant to justify the need to search your property. If an informant's information is used, police must prove that the information is reliable under the circumstances.
This is a quite complicated area of evidence law in the U.S. as there are many statements which are inadmissible under the hearsay rule, but there are also many statements that would otherwise be hearsay that fall within exceptions to the hearsay rule. In U.S. federal court practice, hearsay is governed mostly by Federal Rules of Evidence 103, 104(a), 201, 801-807, and 1101. Most state court rules of evidence in the U.S. with regard to hearsay closely track the Federal Rules of Evidence. Some states do not follow this pattern but are substantively very similar as the Federal Rules of Evidence largely track of the common law rules of evidence before they were codified. Rule 801 provides two exclusions from the definition of hearsay and a foundational definition. Rule 802 prohibits the introduction of hearsay into evidence unless an exception applies. Rule 803 provides 23 exceptions to the rule. Rule 804 provides five more exception to the rule. Rule 807 provides a final residual exception. So, in proceedings where the hearsay rule applies there are 31 main exceptions to the general rule, in addition to the argument that the general rule does not apply, but this still excludes lots of statements. Rule 201 (judicial notice) is another exception. Some of the main reasons to admit hearsay are that: It is not offered for the truth of the matter asserted (e.g. to prove the someone was present and talking at a place not that what they said was true, or to prove that someone said something defamatory or fraudulent, or to prove the someone made a &quot;verbal act&quot; with legal significance like agreeing to a contract or ordering someone to do something). It is a statement of a party opponent or someone affiliated with a party opponent (i.e. someone affiliated with the other side in the lawsuit or criminal case). It is a prior statement of a person made under oath and subject to cross-examination. It is a business record or public record or an &quot;ancient document&quot; (currently ancient means before 1998 in the federal courts, and typically more than twenty-years old in the state courts). It is a market quotation. It is a statement made describing things &quot;in the moment&quot;, for medical diagnosis, or when the facts were fresh in the &quot;declarant's&quot; mind. It pertains to rights in real property, or to family relationships. It is a statement contrary to the interests of the person making it. It is a statement made when the declarant's death was believed to be imminent (i.e. a dying declaration). It is a statement made against someone who caused the witness to be unavailable. There are reasons that the statement is reliable and the intent to provide the statement is cleared with the court in advance. The matter upon which a statement is made is of general public knowledge not reasonably subject to dispute, is easily confirmed without doubt by a court, or is from a learned treatise. Hearsay objections are also waived if a timely objection isn't made to them. See Federal Rule of Evidence 103. And, courts have some discretion to allow hearsay testimony on immaterial matters or matters that are not seriously disputed in the case for expediency's sake. Rules 104(a) (excluding preliminary matters) and 1101 set forth when the hearsay rule applies and when it does not. Rule 1101 excludes from the rule a variety of preliminary matters, mostly in criminal cases such as: grand-jury proceedings extradition or rendition; issuing an arrest warrant, criminal summons, or search warrant; a preliminary examination in a criminal case; sentencing; granting or revoking probation or supervised release; and considering whether to release on bail or otherwise. Rule 805 governs the complicated situation of hearsay within hearsay. Rule 806 coordinates the hearsay rule with rules on how it is proper to introduce evidence about the credibility of a witness. There is also a constitutional rule of criminal procedure, called the &quot;confrontation right&quot; that established minimum standards for the exclusion of hearsay evidence in criminal trials even when a court's procedural rules do not exclude it. Most states also have a hearsay rule pertaining to oral promises made by dead people called the dead man's statute, and limitations on introducing oral statements related to written agreements called respectively, the parole evidence rule and the statute of frauds. In contrast, in the U.K. courts, roughly speaking, hearsay is generally admissible when the person making the underlying hearsay statement is available to testify, or is unavailable, which subsumes a large share of the U.S. hearsay rule, and makes much more hearsay admissible. U.K. practice would also allow admission of almost anything without a U.S. hearsay exception since they are derived from British common law evidence rules related to hearsay. The main purpose of the hearsay rule is to prevent a defendant in a criminal case or lawsuit from being denied an ability to cross-examine witnesses in court because they would like to present evidence by affidavit or letter instead, effectively placing that burden on the prosecution in criminal cases, or on a plaintiff in simple civil cases, rather than forcing the defendant to pro-actively subpoena witnesses for the other side in the case. The rule has a broader sweep than that, but that is its core purpose.
If the victim is unable to prove who the culprit was, then it will be impossible to prosecute that person criminally or sue them for civil damages. Incidents like these are rarely enough to cause a police department to throw sufficient investigative resources at it to crack the case without some reason to believe that it is part of something bigger. An unfortunate fact of life is that most perpetrators of crimes and torts get away with it and are not caught. And, if the only available witness is willing to lie to cover up the name of the guilty party (probably out of a desire to not have the dog put down), it is that much harder. A private investigator might be able to solve the case, but the cost of hiring a PI would probably exceed the benefit that could be obtained if the PI was successful.
I'll use Wisconsin as a jurisdiction. If you file a false death certificate, that's a felony. But you probably wouldn't go that far. It could be disorderly conduct. In Wisconsin disorderly conduct is described as follows: Whoever, in a public or private place, engages in violent, abusive, indecent, profane, boisterous, unreasonably loud or otherwise disorderly conduct under circumstances in which the conduct tends to cause or provoke a disturbance is guilty of a Class B misdemeanor. There's also a statute prohibiting "Disrupting a funeral or memorial service" but it won't apply in this case unless disorderly conduct applies. It would raise the penalty to a class A misdemeanor (or a class I felony if you somehow did it again after being convicted once.) On the civil side, there could be an action for intentional infliction of emotional distress, either for the false report of your death, or for a "corpse" suddenly coming to life. This kind of lawsuit requires "extreme and outrageous conduct", but if this isn't, I don't know what would be.
