Will 3D Printed Fingerprints Unlock a Phone?

iphonefingerprint380

Can someone’s fingerprint be reproduced by 3-D printing technology and if so can it be used to unlock a cell phone? This is intriguing science and currently Professor Anil Jain at Michigan State University is looking into developing this technology. One of the problems is that many cellphone fingerprint security measures require not only pattern recognition but a certain degree of electrical conductivity that is natural to human skin. How to reproduce this in a 3-D printed model is one of the hurdles Professor Jain must overcome. But it is intriguing and we will see how it all shakes out.

Guest Blogger: Lisa Black: Smart Phones and Not-So-Smart Criminals

USING SMARTPHONES TO DEFEAT NOT-SO-SMART CRIMINALS

My boss, the supervisor of our forensic unit, insists that soon we will be able to process an entire crime scene with nothing but a smartphone. Everything from photographs to sketching to measuring to note-taking, all on a 2 ½ x 5” flat item which one needs reading glasses to see unless one is under fifty which I, alas, will never be again.

photo-measure

Most phones now come with 10 or 12 megapixel cameras, which are more than sufficient for forensic purposes. You can get attachments for tripods and flashes. My boss can open and close the shutter from his Apple Watch (important for taking ninety-degree close-ups of fingerprints or tire tracks where the slightest vibration could blur the details).

roomscanpro

Simply browsing through the tablet he got us for crime scene work and nagged us for a few months to use before he finally gave up, I find:

The flashlight app. Of course. (I was at a crime scene yesterday where the two young men were trying to plug my USB into the video system, cleverly hidden in the ceiling panels. It’s dark up there, of course, and they were stymied as they had never downloaded a flashlight to their relatively new phones. I pulled my mini-Mag out of my pocket and suggested they use an actual flashlight. Sometimes us old chicks rule.)

Pill Identifier, with which you can enter the color and shape of a medication and it will help you narrow down to the name of the drug, then link to information on purpose, dosage, side effects and drug interactions.

Photo Measures, which allows you to take a photo of a room and then annotate it with measurements. This way my boss, the detectives, the prosecutors and the jury no longer have to suffer through trying to decipher my hastily scribbled sketches of uneven walls and amorphous blobs representing the pit couch. I can take a photo of the room and write the dimensions right over the picture, then add the feet and inches from the south wall to the bloody knife on the floor. The only catch is you still have to take the measurements yourself.

And for that, we have RoomScanPro. Simply start it up, give each room a name like ‘dining’, hold the phone against each wall, in order but at any particular spot on the wall until you’ve gone around the whole room. The app will create a floor plan including measurements. Do a complete walk-through and it will give you the whole house. Be warned, however, that these apps may only be accurate to half a foot, so that you could wind up with an attorney grilling you how the murder weapon could have been five and a half inches from the victim’s body instead of six.

For traffic incidents, Vehicle Identification System can give you pictures of nearly every make and model available in the last decade to aid witnesses in describing the getaway car. And Cargo Decoder can translate the four-digit DOT code on a truck’s placard to tell you what kind of materials they’re hauling.

There are a number of panoramic photo apps, so that you can quickly scan a 360° shot of the crime scene as is before EMTs, firemen, reporters, angry mobs or bigwig looky-lous breach your perimeter.

So the next time you see a team processing a crime scene it might not only be the nerdy young guy using the newfangled gadgets to do the job. It might be the grizzled old detective using a smartphone and a rubber-tipped stylus.

And reading glasses.

King Henry the VIII’s Brain Injury and Behavioral Changes

henry_viii

King Henry VIII was often a bad boy. I mean, he had two of his many wives executed, for starters. But he was an historical giant—-he took on the Pope and established the Church of England—no small feat in the 1500’s.

But he also developed erratic behavior later in his life. Many date his significant personality change to a head injury following a fall beneath a horse in a 1536 jousting match. He apparently remained unconscious for two hours.

But could a blow to the head cause a dramatic personality change? Absolutely.

There are many types of brain injuries that could lead to such an outcome: Concussions (usually multiple such injuries are needed before personality changes would occur—if at all); Cerebral contusions (brain bruises); intracerebral bleeds (bleeding into the brain tissue; and subdural hematomas (bleeding in the space between the brain and the skull). In Henry’s case, I suspect the later might be the case.

subdural

Subdural Hematoma

Subdural hematomas follow blows to the head and here blood collects in the dural space—between the brain and the skull. It can be small and inconsequential or larger and compress the brain. It can occur immediately or be delayed by hours, days, weeks, and even months. The increased pressure on the brain can lead coma and death. Less dramatically, it can cause headaches, visual impairment, weakness, poor balance, sleepiness, confusion, and, yes, personality changes.

 

The Black Dahlia: The Cold Case That Even 70 Years Later Won’t Go Away

Elizabeth Short

The shocking and graphic murder of Elizabeth Short (The Black Dahlia) has never been solved and likely never will be. Seventy years ago yesterday, on January 15, 1947, the nude body of a young woman was found in a vacant lot on Norton Avenue in the Leimert Park area of Los Angeles. She had been bisected (cut in half) and her two body parts displayed in a spread eagle fashion.

The victim was identified as Elizabeth Short and she soon became known by the moniker The Black Dahlia. Her death has remained one of the truly iconic American crimes. It’s hard to believe that after 70 years little progress has been made in solving her murder.

During the initial investigation, the police were at a loss as to who could have and would have killed Elizabeth, and since then many theories about the killer’s identity have been postulated. But none have ever been proven. Still many are intriguing.

An excellent article from Crime Magazine by Stephen Karadjis was published in 2014. It summarizes the case, its investigation, and the various theories that have circulated about this murder.

 

 

First Successful Insanity Plea in the US

philip-barton-key

Philip Barton Key

“Key, you scoundrel, you have dishonored my house—you must die!”

This words were shouted by US Congressman Daniel Sickles just before he shot Philip Barton Key, a US Attorney and the son of the author of the “Star-Spangled Banner.” And true to his words Sickles shot Key with three different pistols in broad daylight in direct view of the White House. It seems that Sickles had discovered, or at least believed, that Key was carrying on a affair with Sickles’ wife Teresa.

sickles

Daniel Sickles

At the trial, his attorneys employed the insanity defense. In his two-day opening statement, attorney John Graham put it this way:

It may be tragical to shed human blood; but I will always maintain that there is no tragedy about slaying the adulterer; his crime takes away the catcher of the occurrence….the fact is now proved in this case that Philip Barton Key seduced the wife of Daniel E. Sickles, and that for that, in a transport of frenzy, Daniel E. Sickles sent him to his long account.

“Transport of frenzy”? I guess that’s sort of like “going postal.” Temporary insanity as it were.

And of course in that state the only logical action would be to send the scoundrel “to his long account.”

Regardless, Graham’s ploy worked and Sickles was acquitted, served out the rest of his term in the House of Representatives, became a Major General in the Civil War, and was later an ambassador to Spain under US Grant—where he supposedly was the lover of Spain’s deposed Queen.
