making akihiko and chie cops was the dumbest fucking decision ever because i know in my heart that they're actually a physical therapist and professional racecar driver respectively

Cyanide Poison

Let's start by understanding exactly how cyanide kills you. In simple terms, cyanide prevents cells from using oxygen to make energy molecules.

The cyanide ion, CN-, binds to the iron atom in cytochrome C oxidase in the mitochondria of cells. It acts as an irreversible enzyme inhibitor, preventing cytochrome C oxidase from doing its job, which is to transport electrons to oxygen in the electron transport chain of aerobic cellular respiration. Now unable to use oxygen, the mitochondria can't produce the energy carrier adenosine triphosphate (ATP). Tissues that require this form of energy, such as heart, muscle cells, and nerve cells, quickly expend all their energy and start to die. When a large enough number of critical cells die, you expire as well. Death usually results from respiratory or heart failure.

Immediate aymptoms include headaches, nausea and vomiting, dizziness, lack of coordination, and rapid heart rate. Long exposure symptoms include unconsciousness, convulsions, respiratory failure, coma and death.

A person exposed to cyanide may have cherry-red skin from high oxygen levels, or dark blue coloring, from Prussian blue (iron-binding to the cyanide ion). In addition to this, skin and body fluids may give off an almond odor.

The antidotes for cyanide include sodium nitrite, hydroxocobalamin, and sodium thiosulfate.

A high dose of inhaled cyanide is lethal too quickly for any treatment to take effect, but ingested cyanide or lower doses of inhaled cyanide may be countered by administering antidotes that detoxify cyanide or bind to it. For example, hydroxocobalamin, natural vitamin B12, reacts with cyanide to form cyanocobalamin, which leaves the body in urine.

These antidotes are administrated via injection, or IV infusion.

Cyanide is actually a lot more common than you'd think. It's in pesticides, fumigants, plastics, and electroplating, among other things. However, not all cyanide are so poisonous. Sodium cyanide (NaCN), potassium cyanide (KCN), hydrogen cyanide (HCN), and cyanogen chloride (CNCl) are lethal, but thousands of compounds called nitriles contain the cyanide group, yet aren't as toxic. They still aren't terribly good for you, so I wouldn't go around ingesting other cyanide compounds, but they're not quite as dangerous as the lethal kind.

Thank you for reading, have a lovely day :)

Forensic Linguistics

Here is a glossary of key terms related to Forensic Linguistics:

1. Forensic Linguistics: The application of linguistic knowledge, methods, and techniques to legal and criminal investigations, including the analysis of spoken and written language for legal evidence.

2. Linguistic Analysis: The systematic examination and interpretation of language, including its structure, usage, and meaning, to uncover insights and evidence in legal contexts.

3. Authorship Attribution: The process of determining the author or origin of a written text by analyzing linguistic features, such as writing style, vocabulary, and grammar.

4. Linguistic Profiling: The analysis of language to create a profile of an individual, including their demographic information, cultural background, and psychological characteristics.

5. Discourse Analysis: The study of language in use, focusing on how language is structured and used in different contexts, such as conversations, interviews, and legal proceedings.

6. Stylistic Analysis: The examination of linguistic features, such as word choice, sentence structure, and tone, to identify patterns and characteristics that can help identify the author or origin of a text.

7. Phonetics: The study of the physical aspects of speech sounds, including how they are produced, transmitted, and perceived.

8. Phonology: The study of the organization and patterns of sounds in languages, including the rules and structures that govern their use.

9. Morphology: The study of the structure and form of words, including how words are constructed from smaller meaningful units called morphemes.

10. Syntax: The study of the structure and arrangement of words to form grammatically correct sentences and phrases.

11. Semantics: The study of meaning in language, including how words and sentences convey ideas and information.

12. Pragmatics: The study of how language is used in real-world contexts, including the role of context, social factors, and implied meanings in communication.

13. Linguistic Variation: The study of how language varies across different speakers, dialects, regions, and social groups.

14. Sociolinguistics: The study of how language and society interact, including the social and cultural factors that influence language use and variation.

15. Language Documentation: The process of recording and preserving endangered languages, including their grammar, vocabulary, and cultural context.

16. Expert Witness: A professional who provides specialized knowledge and expertise in a particular field, such as forensic linguistics, to assist in legal proceedings and provide expert testimony.

17. Legal Discourse: The language and communication used in legal contexts, including legal documents, court proceedings, and legal arguments.

18. Miranda Rights: The rights of individuals in the United States, as established by the Supreme Court case Miranda v. Arizona (1966), which include the right to remain silent and the right to have an attorney present during police interrogations.

19. Linguistic Evidence: Language-based evidence, such as written documents, recorded conversations, or linguistic analysis, that is used to support or refute claims in legal proceedings.

20. Linguistic Proficiency: The level of skill and competence in a particular language, including the ability to understand, speak, read, and write in that language.

The Case of Jeffrey Dahmer:

Sexual Serial Homicide from a Neuropsychiatric Developmental Perspective

J. Arturo Silva, M.D

Michelle M. Ferrari, M.D

Gregory B. Leong, M.D

)c(

"Sexual serial homicidal behavior has received considerable attention during the last three decades. Substantial progress has been made in the development of methods aimed at identifying and apprehending individuals who exhibit these behaviors. In spite of these advances, the origins of sexual serial killing behavior remain for the most part unknown. In this article we propose a biopsychosocial psychiatric model for un- derstanding the origins of sexual serial homicidal behavior from both neuropsychiatric and developmental perspectives, using the case of convicted serial killer Jeffrey Dahmer as the focal point. We propose that his homicidal behavior was intrinsically associated with autistic spectrum psy- chopathology, specifically Asperger’s disorder. The relationship of Asperger’s disorder to other psychopathology and to his homicidal behavior is explored. We discuss potential implications of the proposed model for the future study of the causes of sexual serial homicidal criminal."

What I'm liking about Red Dragon so far (and why I like Manhunter better as an adaption than Red Dragon) is the focus on the process of investing rather than sensationalizing the gruesome murders

[swordmaid]

playing dress ups in piccrew with my ocs as one does and now I am thinking up of a regency or victorian era based murder mystery au with thalia as main char or something ,,,, anyway chars go from thalia left shri’iia right

then yves as creepy nun and wren as the one sole dude in this line up

[nuks]

an oc who’s father is an infamous serial killer… the oc hates her father, who she turned in when she found out about his crimes… but they like fought, he stabbed her several times, but she managed to survive…. And as the cops like dragged his ass off he was monologuing about finding her one day and killing her (inspired by this speech LOL) so now she has to live in paranoia despite him being locked away sighhhhh

Choosing the Right Type of Forensic DNA Testing

DNA testing has revolutionized how investigators solve crimes and identify victims, as well as the exoneration of the innocent. As there are various types of forensic DNA testing available, understanding the differences can help law enforcement and legal professionals navigate the labs to contact and the conversations that will take place.

STR Analysis (Short Tandem Repeat)

This is the most widely used method in forensic DNA testing. It examines specific regions of DNA that vary greatly among individuals. This technique is especially effective for human identification in criminal cases due to its high degree of specificity and reliability.

mtDNA Analysis (Mitochondrial DNA)

This analysis is used when nuclear DNA is degraded or unavailable, often in older samples. It examines the maternal lineage and can provide valuable insights in cases involving skeletal remains or hair samples. While less discriminative than STR, mtDNA can still be crucial for historical cases.

Y-STR Analysis

Y-STR targets the Y chromosome, making it ideal for tracing paternal lineage. This method is particularly useful in sexual assault cases where male DNA is mixed with female DNA, allowing forensic analysts to isolate male-specific markers for identification.

SNP Analysis (Single Nucleotide Polymorphism)

This emerging technique is often headlined in the industry and focuses on variations at specific single nucleotide sites in the DNA sequence. It's useful for ancestry testing, specifically forensic genetic genealogy in criminal cases, and can provide additional information when traditional methods are inconclusive.

DNA Phenotyping

While not a standard method for identification, DNA phenotyping can predict physical traits such as eye color, hair color, and skin tone from DNA samples. This approach can assist in generating leads when suspects are unknown, particularly in cases with minimal evidence.
