Shock: Amanda Dufrene, 30, said her son Carson had scratches to his ears, forehead, arms, ankle, foot, calf and fingers when she took him home from a daycare centre in Louisiana

This amazing article  documents how human bite marks on a single victim, arguably by one suspect, are extremely inconsistent in pattern, shape of tooth marks and other details. Here’s a few questions. Would you look at the bite marks before looking at this suspect’s teeth? Which mark would you pick to compare to the suspect’s teeth? If you pick one, why did you not use any others? Is it because one shows more teeth marks? Of course. Doing anything (like “matching” or “suggesting” or “including” or “excluding”) beyond this then requires you to assume that this one mark is a correct representation of the biter’s front teeth physical characteristics (and the other marks are NOT). That’s where all the mistakes start by the “skin-reading” bite mark experts.

This case also proves how human bite marks can cause serious infection.

Justice Kozinski on Lying Police and more on forensic science and CJ “guesswork”

Judge Alex Kozinski, U.S. Court of Appeals for the Ninth Circuit (official photo).

EVIDENCE OF POLICE DISHONESTY LEADS TO OVERTURNED CONVICTIONS NATIONWIDE

Here are some quotes from a justice of the US Ninth Circuit of Appeals. Justice  Alex Kozinski talks about police misconduct and worse in the Debra Milke case.

“The Ninth Circuit was so disturbed by Milke’s case that the panel referred its opinion to the U.S. Attorney for the District of Arizona and the Assistant U.S. Attorney General of the Civil Rights Division “for possible investigation into whether Saldate’s conduct, and that of his supervisors and other state and local officials, amounts to a pattern of violating the federally protected rights of Arizona residents.”

Kozinski learned through the media that nothing came of the referral.

“They do not consider lying cops to be quite the same priority as shooting cops,” Kozinski said during an interview. “Maybe because they don’t get riots and they don’t get the same kind of public reaction as when police shoot somebody, but in essence it’s the same thing.

“They are helping commit violence against the suspect by words, but words can have the same effect,” Kozinski said. Full article. 

Here is a real blockbuster from Justice Kozinski.

12 reasons to worry about our criminal justice system, from a prominent conservative federal judge

Originally from the Georgetown Law review. Article is written by Eugene Volokh.

“Although we pretend otherwise, much of what we do in the law is guesswork. For example, we like to boast that our criminal justice system is heavily tilted in favor of criminal defendants because we’d rather that ten guilty men go free than an innocent man be convicted. There is reason to doubt it, because very few criminal defendants actually go free after trial.”

One of his sections includes a mention of forensic science’s mythic prominence.

3. Other types of forensic evidence are scientifically proven and therefore infallible.

Remains of Nazi anatomy prof’s victims found at French forensic institute

Nazi anatomist’s collection of Holocaust victims “discovered” in France.  A horrible period in European history. Human experimentation by the Third Reich and its collaborators.

The endless story about untested rape kits leads to Idaho. You can tell LE is predominantly run by men.  So much for “protecting.” Also in Asheville, TN, home of the FBI’s own crime lab. Media reporting it “a stab in the heart.”

A hit it for TN medical investigations as a very qualified ME  goes elsewhere for more opportunities. 

British crime lab a  blend of public specialists and private forensic vendor acts as a money saver.  (free signup at the “Police Oracle.”

TX crime lab DWI tech gets the lab in trouble.

“In May, the Tarrant County district attorney’s office sent out more than 180 notices to defense attorneys saying it had banned Elizabeth Feller from testifying in any future DWI cases. Feller worked as a lab analyst for Integrated Forensics Laboratories, which tests blood samples for several regional law enforcement agencies.” Full article.

#SandraBland | Circumstances of a murder staged as a suicide?

More info on the signs of hanging versus asphyxiation. There is a recent sci paper describing a murder staged as a hanging suicide.
Plus from Mary Beth Hauptle.
“The ligature furrow mark in the neck ought be a characteristic inverted “V”, if she hanged herself. I would obtain other inmate “witness” statements as to what they did or did not overhear, coming from her cell.”

Let’s see if we can start a thread from the forensic community about some of these issues .

The family of Sandra Bland, who died while in a county jail in Texas this week, has made it clear that the authorities’ (at this point the police in charge of the jail) statement that she committed suicide by self-asphyxiation is unacceptable and patently questionable.

A forensic re-phrasing of what the family says is that her asphyxiation was “staged” to look like suicide. That changes the manner of death to murder, not suicide.

So what proof is necessary to determine such a change in this outcome? Remember she was asphyxiated by a trashbag.

I am not a pathologist, but the the following  first came to my mind about the possibility of what physical evidence could support the family’s current position of rejecting what the authority have claimed up to this point. This…

#SandraBland | Circumstances of a murder staged as a suicide?

So what proof is necessary to determine such a change in this outcome? Remember she was asphyxiated by a trashbag.

I am not a pathologist, but the the following  first came to my mind about the possibility of what physical evidence could support the family’s current position of rejecting what the authority have claimed up to this point. This is by no means a comprehensive list. The media and the family’s representatives will need to know.

The best scenario for the family would be:

1) Authorities immediately followed proper crime scene protocol after the body was discovered. This means isolating the jail area (beyond the immediate cell) from any unnecessary access. Were EMT’s called? Some say not.  In any event, the trashbag becomes the prime source for fingerprints and “touch DNA” collection. If no EMTs arrived, its a surety that jail personnel touched it. Let’s hope that they were wearing surgical gloves. If not, there could also be prints etc. from whomever originally placed it in the cell. Or maybe someone else directly involved in this mystery.

2) Sandra’s full autopsy being performed by a certified forensic pathologist. They seem to be plentiful in Texas an though in some areas the pathologist is not local. Headline cases like this commonly have the family hiring a second forensic pathologist to review the records of the state’s medical expert. Rarely, if ever, would a family retained pathologist be permitted at the primary autopsy.

3) The autopsy itself. The external inspection of her remains is particularly crucial. Victims of murder are not cooperative and signs of a struggle (not resuscitation efforts) relating to bruising, torn fingernails (also a source of a perp’s DNA from being scratched) would be compelling evidence to rebut the claim of suicide.

4) Lets see what other qualified folks can add to this list.

Federal court opens door for “new” DNA tests

Forensic science advances get another boost. This quashes DAs disingenuous arguments that appeal litigation for additional DNA testing is bound by a time “statute of limitations.” The rub are states’ laws that require a standard of proof of innocence that is higher than what is used for gaining a conviction. California DA Association is on board to battle the application of a new CA law addressing this issue. Seems that “finality of guilt” is their motto.

http://www.allgov.com/news/top-stories/federal-court-rules-that-improved-dna-testing-technology-means-forensic-samples-from-past-crimes-must-be-treated-as-new-evidence-150717?news=856984

Just published. Seems like a form of unionized form of job protection.

DAs rally for more drug enforcement and prisons to protect us from a lowering crime rate.

Bizzaro lawsuit claims ex crime lab tech driven to suicide.
