Protocols That Were Considered Normal 1,000 Years Ago — DiscoverNet

Modern people aren’t exactly without our flaws, but for the most part we’re less willfully creepy than our forebearers.

INTRODUCTION

✴ The term “biometrics” is derived from the Greek words “bio” (life) and “metrics” (to measure).
✴ Biometrics is the technical term for body measurements and calculations.
✴ Biometrics is the measurement and statistical analysis of people’s unique physical and behavioral characteristics.
✴ Biometrics allows a person to be identified and authenticated based on a set of recognizable and verifiable data, which are unique and specific to them.
✴ Biometrics authentication is the process of comparing data for the person’s characteristics in order to determine resemblance.

TYPES OF BIOMETRICS

Biometrics Can Be Divided Into Three Main Categories Of Characteristics:
1. BIOLOGICAL
2. MORPHOLOGICAL
3. BEHAVIORAL

⏩DNA MATCHING

The identification of an individual using the analysis of segments from DNA.

👂EAR

The identification of an individual using the shape of the ear.

👀EYES – IRIS RECOGNITION & RETINA RECOGNITION

👁IRIS RECOGNITION- The use of the features found in the iris to identify an individual.
👁RETINA RECOGNITION- The use of patterns of veins in the back of the eye to accomplish recognition.

👱‍♂️FACE RECOGNITION

The analysis of facial features or patterns for the authentication or recognition of an individuals identity.

🤘FINGERPRINT RECOGNITION

The use of the ridges and valleys (minutiae) found on the surface tips of a human finger to identify an individual.

👋FINGER GEOMETRY RECOGNITION

The use of 3D geometry of the finger to determine identity.

🤚HAND GEOMETRY RECOGNITION

The use of the geometric features of the hand such as the lengths of fingers and the width of the hand to identify an individual.

🙌VEIN RECOGNITION

Vein recognition is a type of biometrics that can be used to identify individuals based on the vein patterns in the human finger or palm.

👃ODOUR

The use of an individuals odour to determine identity.

✍SIGNATURE RECOGNITION

The authentication of an individual by the analysis of handwriting style, specifically the signature. Technology is available to check two scanned signatures using advances algorithms.

👩‍💻TYPING RECOGNITION

The use of the unique characteristics of a persons typing for establishing identity.

🗣VOICE / SPEAKER RECOGNITION

There are two major applications of speaker recognition:
🙊Voice – Speaker Verification / Authentication
🙊Voice – Speaker Identification
✔In forensic applications, it is common to first perform a speaker identification process to create a list of “best matches” and then perform a series of verification processes to determine a conclusive match.
✔Voice recognition analyzes audio input for specific patterns in speech or sound. Each voice, or common noise, has a recognizable wavelength pattern that can aid in identification of a specific individual.

🚶‍♀️👣GAIT

The use of an individuals walking style or gait to determine identity.

Biometrics allows a person to be identified and authenticated based on a set of recognizable and verifiable data, which are unique and specific to them. This video covers following Points of Biometrics: 💡Introduction 💡Characteristics 💡History & 💡Types.

Variables to consider when Determining Post Mortem Blood Alcohol Levels via True Crime Rocket Science / #tcrs

Immediately following the release of the autopsy reports on November 19th, I contacted Thomas Mollett, a forensic investigator, fellow true crime author and friend, and asked him his opinion on Shan’anns Blood Alcohol Levels. They were found to be three times the legal limit for driving. How likely was it, I asked, that these apparently high levels were from “normal” decomposition?

Pathology is an extremely complex science, and many factors play into the biological processes that occur after death.

image001

The three basic pillars one uses to calculate whether the BAC is “normal” or not are related to:

  1. the time the body is exposed to the elements [here time of death is a factor, unknown in this case, but with a relatively short window either way]
  2. the ambient conditions of the body [temperature, humidity etc.]
  3. circumstantial evidence is also a vital tool to gauge alcohol content, including eye witnesses, Shan’ann’s drinking habits, and her appearance in the Ring camera footage when she arrived home [described but not released thus far]

During our first communication I miscommunicated to Mollett that Shan’ann’s corpse was recovered after only 48 hours, which I guessed wasn’t enough time to reflect the high alcohol levels found. This was an initial error on my part; it took closer to 70 hours for Shan’ann’s corpse to be discovered and exhumed.

Based on this initial miscommunication, Mollett also believed the BAC level was likely higher than a natural rate [which as I say, was also what I suspected].

I asked Mollett to investigate the BAC levels and I’m grateful to him for doing so in detail. Obviously part of his thorough investigation corrected the original 48 hour error.

Below is Mollet’s unabridged report on the BAC levels.

    I think Chris tied Shanann to the bed after she fell asleep, put a pillow case over her mouth to prevent her from screaming, made sure she watched through the monitor how he smothered Bella and Celeste, and then came back to the bedroom to strangle her.

    Well, that report certainly cleared up so many things. Now we know. The body certainly is a fascinating animal in death as much as life. I do know that when officer Coonrod was in the kitchen he didn’t have a peek in the sink to see if there were breakfast dishes in there to find out if the kids had eaten so we couldn’t see if there was a wine glass. Nor did I see any at all throughout his whole walk through the house. Thorough report

    “Important moments at Watt’s well site” is really stunning. I hope everyone can blow it up on a computer monitor rather than a cell phone. You really get the sense of vastness of that site – miles and miles in every direction of land dotted with wildflowers. The tank battery site even seems dwarfed in proportion to the land. As the drone makes it’s lazy pass from the air you then see the sheet, hugging the scrub. Look a little closer and you see the black garbage bags. It was rather stupid of him to discard the sheet on top of the land after it had fulfilled it’s purpose to conceal and drag. Same with the garbage bags. Maybe he thought in the vastness of the land those items, like his family, would simply vanish.

    Sylvester, do you know if they sent the drone out before Chris said anything or after? For the life of me, I can’t remember. Thank you kindly
