Police cloned a Michigan murder victim’s fingerprint that unlocked his phone — Quartz

Cracking crime just got a lot more innovative.

Police and biometrics researchers at Michigan State University have successfully unlocked the smartphone of a murder victim by using a digitally enhanced print-out of his fingerprint.

Officers from the digital forensics and cyber-crime unit at MSU’s police department approached the college’s biometrics research lab last month, having become aware of the team’s research (pdf) on how printed fingerprints can spoof mobile-phone sensors.

Police had the fingerprints of the murder victim from a previous arrest, which they gave to the lab to 3D print in a bid to unlock the device—a Samsung Galaxy S6.

Unsure which finger was paired to the phone, the lab printed 2D and 3D replicas of all 10 of the slain man’s fingerprints. None of them unlocked the device, so the team then digitally enhanced the quality of prints by filling in the broken ridges and valleys. Rather than opting for a more expensive 3D model, they printed new 2D versions using a special conductive ink that would create an electrical circuit needed to spoof the phone sensor.

After multiple attempts—thanks to the device not requiring a passcode after a certain number of efforts—the team successfully unlocked the phone with one of the digitally enhanced 2D prints.

An MSU spokesperson told Quartz there were plans to print 3D models to test on other devices—there was no need to do so for the victim’s phone, as the 2D print was successful.

Professor Anil Jain, who led the research team at MSU, says the unlocking demonstrates “a weakness” in smartphones’ fingerprint authentication systems, and that he hoped it would “motivate phone developers to create advanced security measures for fingerprint liveness detection.” He added:

This shows that we need to understand what types of attacks are possible on fingerprint sensors, and biometrics in general, and how to fix them. If we don’t, the public will have less confidence in using biometrics. After all, biometric authentication was introduced in consumer devices to improve security.

According to MSU, this is the first time law enforcement has used such technology as part of an ongoing investigation. A spokesperson said the lead detective “even contacted the company that was asked to help with [unlocking] the San Bernardino shooter’s phone and he kept getting the same answer: can’t do it, the tech doesn’t exist. Well, the tech exists now!”

In a statement, Samsung said:

We are aware of the research from Michigan State University, but would like to remind users that it takes special equipment, supplies and conditions to simulate a person’s fingerprint, including actual possession of the fingerprint owner’s phone, to unlock the device. If there is a potential vulnerability or a new method that challenges our efforts to ensure security at any time, we will respond to issues as quickly as possible to investigate and resolve the issue

this day in crime history: august 26, 1980

On this date in 1980, two men made an early morning delivery of what appeared to be computer equipment to the Harvey’s Resort and Casino in Stateline, NV. Harvey’s employees soon discovered the “computer equipment” and the note attached to it. The note informed them that the large package was a bomb, and that it would go off unless the bombers were paid $3 million by the casino.

Police, the FBI, and the ATF were called in. Bomb squad personnel examined the object and confirmed that it was a bomb. The device, which was very sophisticated, contained a large amount of dynamite.

The decision was made to pay the ransom, then concentrate on tracking down the extortionists later. Unfortunately, the delivery of the ransom money – which was to be done by police helicopter – didn’t go off as planned. This left the bomb squad with the task of figuring out how to disarm the largest dynamite bomb anyone in law enforcement had ever seen.

After x-raying the equipment and carefully examining it, the explosive ordnance disposal experts decided that the best was to disarm it way to quickly disconnect the detonators before they could set off the dynamite. To do this, they rigged shaped charges of C-4 and positioned them so they would blow the detonators off. Sand bags were stacked around the bomb to minimize the damage in case the plan didn’t work. This was a good idea, as the plan didn’t work. The shaped charges set the bomb off, destroying most of the casino and causing some damage to the neighboring hotel. Thankfully, there were no injuries from the explosion.

As the ensuing investigation unfolded, a suspect soon emerged: a Hungarian immigrant from Clovis, CA named John Birges. Birges, as it turned out, lost thousands of dollars gambling at Harvey’s. (note to all you high rollers out there: You can lose. That’s why they call it “gambling.”) In the summer of 1981, investigators received a tip that Birges had stolen dynamite from a construction site. Forensic examination matched the dynamite used at the site with that used in the Harvey’s Casino bomb. John Birges was arrested in August 1981, almost a year after the bombing. His three accomplices were soon arrested as well. It wasn’t long before they flipped and agreed to testify against Birges in exchange for lighter sentences. John Birges was convicted of multiple state and federal crimes. He died in prison of liver cancer in 1996.

The Making of a Serial Killer / Child Molester: How to improve Police-Community relations?

What’s missing in how to improve police-community relations?

Written on 5/27/201529uwo0l

It’s amazing that no federal, state or municipal political leader; no police administrator; and certainly no media talking head has come forward to ask why only ONE side of the narrative of how police-community relationships should change.

The clear theme that is evident in ALL of these police-involved citizen deaths is that a history of bad life choices made by citizens creates a confluence of circumstances resulting in unintended consequences that unfortunately have led to the deaths of those portrayed in the media and by uninformed activists as “innocents.”

Bad parenting, no parenting, the irresponsibility of young males to impregnate young naive females and then abandon their parental responsibilities; failing to embrace the benefits of education; failure to develop meaningful job skills; drugs abuse; gang involvement; embracing and glorifying gangsta rappers who forward a destructive narrative of drugs, crime, and disrespect/violence against police.535cc702-6d8c-479b-96e8-65c869e0eb6d-original

Nearly every so-called “victim” of these recent police-involved deaths had a history of criminal arrests; were fleeing from detention and arrest on foot and/or in vehicles; had verbally and physically resisted detention or arrest; had assaulted police with weapons; were in possession of weapons; and/or were under the influence of drugs during the encounter and altercations.

Where is the public’s ownership of these poor life decisions? Why aren’t the parents, the political leaders, the community activists, the media talking heads, celebrities, nationally prominent athletes and the jet setting, race bating civil rights “activists” such as Jesse Jackson and Al Sharpton extolling our children and citizens NOT to make these very obvious and poor life choices?

Why do some communities seem to have an overwhelming number of violent crimes, high levels of gang violence and drug abuse and interactions with police – and others either very low or almost no such instances? And why aren’t the obvious differences in these communities discussed?

Why are the false narratives such as “Hands up. Don’t shoot.” forwarded by the media, street activists, and our political leaders? Why are some segments of American society more intent upon assigning blame to the police; rather than accepting responsibility for their poor life choices?

The police are not psychologists, sociologists, criminologists and mental health practitioners. They are “First Responders.” Police respond to society’s problems; they can’t fix them. Police officers come from our communities; not from distant planets. They are us and we are them. Police get the training that YOU provide them with. Can they be better trained? Of course. Do they want and ask for better training and equipment? All the time, but YOU don’t want to pay for it. Do police need to be smart and better educated? Of course, but the problem is that agencies can’t find qualified officers because many who apply lack even the most basic education and personal skills to pass the tests to become a police officer. How are these issues the fault of police? Yet the public, politicians and the media consistently heap criticism on them.

If you want a dramatic national change in police-community relations, begin by first looking into the mirror as citizens and as a society and ask yourselves what are YOU willing to do to bring about this needed change? When will YOU begin accepting responsibility for YOUR actions? When you take this first step, you begin the journey upon the road towards positive change between yourselves and your police.

Inmate who killed Jeffrey Dahmer reveals why he murdered the serial killer

CANON CITY, Colo. — The inmate who fatally beat serial killer and sex offender Jeffrey Dahmer in prison in the early-1990s has revealed his reasons for doing so in a new interview.

Christopher Scarver, who was incarcerated at the same Portage, Wisc., prison as Dahmer back in 1994, recently divulged the details of his killing to the New York Post.

“Some people who are in prison are repentant — but he was not one of them,” he told the Post, recounting details of Dahmer’s brutal and unapologetic taunts to other inmates.

Scarver said in the interview Dahmer used to fashion limbs out of the prison food, applying ketchup on places to represent blood.

Though they were taunts, the actions represented a more chilling reality. Dahmer was arrested in 1991 after police found human remains and decomposing bodies in his apartment. Dahmer later confessed to 17 murders, many of which included the rape and dismemberment of the victims.

In 1992 Dahmer was sentenced to 15 life terms in prison after a court rejected his insanity defense.

Despite Dahmer’s abominable past, Scarver told the Post the killer initially left “no impression” on him.

“I never interacted with him,” he told the Post. He would watch from afar, avoiding contact due to Dahmer’s friction with other inmates.

That was until Nov. 28, 1994.

Dahmer, 34 at the time, and another inmate were tasked to clean the bathrooms — unshackled and unattended.

Scarver, then 25 and himself a convicted murderer, was with them. He told the Post he’d kept a newspaper clipping that detailed Dahmer’s killings.

He found his fellow inmate to have a lust for flesh, and was “disgusted” with the details of his actions.

Scarver told the Post he’d gone to retrieve a mop when he felt someone poke his back. When he turned around, he saw Dahmer and the other inmate “laughing under their breath.”

“I looked right into their eyes, and I couldn’t tell which had done it,” he told the Post.

But after the three men split up, Scarver decided to follow Dahmer to the locker room.

He told the Post he confronted Dahmer with the news article, asking the killer if he’d really done the things described in the story.

When Dahmer tried to escape, Scarver then took a metal bar and swung it at his head, crushing Dahmer’s skull.

Scarver then found the other inmate, Jesse Anderson, and did “[p]retty much the same thing.”

Scarver told the New York Post he believes the prison officials left them all alone on purpose, knowing he hated Dahmer and wanted him dead.

“They had something to do with what took place. Yes,” he told the Post.

After the murders, he pleaded insanity, but later changed it to “no contest” in exchange for a transfer to a federal penitentiary.

According to the New York Post, Scarver was then sentenced to two life terms on top of the one he was already serving at the time.

Scarver had been sentenced in 1990 for the murder of his former boss during a robbery, the Post notes.

He is currently incarcerated at Centennial Correctional Facility in Canon City, Colo.

Scarver now spends some of his time writing poetry for his website.  Related: http://www.mirror.co.uk/news/world-news/why-killed-jeffrey-dahmer-prisoner-5600323?ICID=FB_mirror_main
