Aaaandd, we still don’t know who Jack the Ripper was.

Looks like I posted a little to quickly. Now now, I am not saying that Aaron Kosminski wasn’t the ripper I am saying the DNA is far from conclusive.

MtDNA is passed down from a mother to her children, and many people can share the same mtDNA signature. The signature linked to Kosminski, T1a1, is a relatively common subtype. Thus, the determination doesn’t mean much unless the signature can be narrowed down to a rarer subtype, or unless additional evidence can be brought to bear (as was the case for identifying the remains of Russia’s Czar Nicholas II and his family).

A larger question has to do with the scarf’s history: It’s been open to contamination for decades, and it’s not even clear that it was really left behind by Eddowes (or her killer) after the 1888 murder. “In the community of so-called experts, it’s not really considered evidence,” Ryder said.

Casebook Jack The Ripper is also not convinced and since that is THE place for Ripperplogists I give them weight.

The History Channel has a good article on this. The chain of evidence for the shawl tested is a little sketchy to say the least.

The Victorian-era shawl reportedly taken by Simpson passed from generation to generation of the policeman’s descendants until it was put up for auction in 2007 and purchased by Russell Edwards, an English businessman and self-confessed “armchair detective” who was fascinated by the coldest of cold cases. Although the silk fabric was frayed and aging, it still contained valuable DNA evidence since it was never washed. Now, after more than three years of scientific analysis, Russell says that Jack the Ripper’s true identity has been found interwoven in the ragged, 126-year-old shawl, and he fingers Polish immigrant Aaron Kosminski as the serial killer in his new book “Naming Jack the Ripper.”

I haven’t read the book yet but if any of you have please let me know what you think,

As of now even though I would have loved to have a name I also kind of like the mystery in this one case. Usually I really want the killer named this one though…. ?

Judge in ‘Grim Sleeper’ serial murder case OKs use of DNA

Article here

Rejecting defense arguments that a suspect in the slayings of 10 women and the attempted murder of an 11th had a reasonable expectation of privacy in the DNA he left on pizzeria plates and utensils, a California judge on Tuesday OK’d the evidence gathered by a police officer who posed as a restaurant busboy.

The ruling by Los Angeles County Superior Court Judge Kathleen Kennedy helps clear the way for the case against Lonnie Franklin Jr. to proceed toward trial this summer, reports the Los Angeles Times. Franklin, who is about 60 years old, is being held without bail following his arrest in 2010.

The suspect in the case was nicknamed the “Grim Sleeper” because of a seeming years-long hiatus in slayings that took place over a period of over 20 years, according to authorities.

Although his DNA was not initially in a database available to law enforcement, investigators focused on Franklin as a suspect after asking the state to try to match DNA recovered at the crime scenes to individuals in the database who might be a relative of the suspect.

He is not even arguing that it is his DNA only that the cops obtained it the wrong way. I do not care how the cops got his DNA I am just happy that they finally took this bastard off the streets.

Life Does Not Mean Life Even For Serial Killers

It was a bright day for justice when legislation allowing consecutive sentences for multiple murderers was given royal assent earlier this year.

The prospect of serial killers being eligible for parole after 10 or 25 years, depending on whether it was second-degree or first-degree murder, has grated on Canadians and caused immense anguish for victims’ families.

Fortunately, the federal Conservatives closed that despicable loophole, ending sentence discounts for multiple murderers. The law permits judges to impose consecutive periods of parole ineligibility on people convicted of more than one murder.

So when Joseph Laboucan, 26, was swiftly convicted of first-degree murder Monday — his second murder conviction in four years — I expected Canadian judicial history to be made in Edmonton Court of Queen’s Bench.

In 2007, Laboucan was sentenced to life with no chance of parole for 25 years for the sadistic rape-murder of 13-year-old Nina Courtepatte, who was lured away from West Edmonton Mall on April 3, 2005.

Two days earlier, Laboucan killed prostitute Ellie May Meyer, 33, after picking her up on 118 Avenue with two friends. He had sex with her in a field, beat her to death and cut off part of her left pinkie finger as a trophy.

Laboucan, I assumed, would be the first serial killer in Canada to be hammered with consecutive sentences. He’s got another 21 years to serve for Courtepatte’s murder before he can apply for parole, so adding another 25-year parole ineligibility period would mean he’d spend 46 years in the clink before being considered for release.

Alas, I was far too optimistic. Even though Laboucan’s most recent murder conviction was handed down Monday, the new legislation doesn’t apply to him.

Why? Because the murders took place before the legislation was passed. And because of another legal technicality: although the law received royal assent in March, it’s still not in effect. The law is to come into force on some future date set by the Governor General. It makes you want to rip your hair out.

Not only must this be demoralizing for the families of Courtepatte and Meyer, it will be a shock to the relatives of all the Alberta women who’ve gone missing (and were presumably murdered) over the years.

Even if a serial killer is caught, he will be eligible for parole after 25 years, no matter how many people he killed.

In Laboucan’s case, he committed two murders for the price of one. Clifford Olson, the poster boy of savagery now dying of cancer, committed 11 murders for the price of one — with the right to apply for parole every two years after he’d spent 25 years in jail.

As former Alberta prosecutor Scott Newark points out, it’s as if all the other victims are of no consequence.

“The way our law was designed so many years ago, nobody … ever really thought through all of that,” he says.

It’s too bad Laboucan couldn’t have been hit with a 46-year sentence, adds Newark. He figures federal justice officials were leery of allowing the new law to apply in previous murders, even if the killers aren’t caught until later. “I refer to it as charter angst,” says Newark.

Laboucan isn’t eligible for parole until he serves 25 years of his latest sentence, says Crown prosecutor Doug Taylor.

“With or without the new parole eligibility requirements, the reality of two life sentences is he will likely be in prison the rest of his life.”

Sorry, but that’s little comfort to those who were hoping for harsher justice for serial killers.

I agree Ms. Jacobs. Excellent article, I hope that the judges listen!

A little information on Laboucan:

 

Laboucan, who is already serving a life sentence for the murder of 13-year-old Nina Courtepatte, pleaded not guilty to the charge of first-degree murder in the death of the sex trade worker back in April 2005. Still, his lawyers did not present any evidence or challenge any Crown exhibits.

Submitted for consideration was testimony from the preliminary hearing, where an eyewitness said she saw Laboucan chasing and repeatedly swinging something at Meyer’s head.

Multiple people also swore the now 26-year-old showed off a severed pinky finger, which the accused told them was a souvenir from one of his victims. DNA later confirmed the body part belonged to the 33-year-old street worker.

In delivering his decision, the judge said he believed the testimony of one youth who said Laboucan got an adrenaline rush from killing Meyer, and wanted to do it again.

RCMP believe just days after Laboucan killed the Edmonton woman and dumped her body in a field, he led Courtepatte to a golf course just outside the city, and committed the second murder.

The Crown says through Courtepatte’s case, they were able to gather key DNA evidence that tied the accused to Meyer’s death.

It is such a scary thought that serial killers can be released.

We know that they do not ‘get better’. We can not ‘cure’ them, the only behavior modification that works is death.

How many bodies will court systems allow to pile up before we stop letting serial killers out?

Serial Killer Sonny Pierce Charged.

A Blue Island man accused of killing three teenagers and raping a fourth was formally charged with their murders Monday.

Sonny Pierce, 27, is charged in the August 2010 sexual assault of a 15-year-old girl. DNA collected during that investigation linked him to the murders of two other teens, police said. A computer seized during those investigations connected him, prosecutors said, to a third victim whose body has not been found.

Pierce was indicted Monday with three counts of first-degree murder and an arraignment date was set for May 25, Cook County State’s Attorney’s office spokesman Andy Conklin said.

Pierce was ordered held without bail April 20.

Kimika Coleman, 18, of Chicago, was found strangled in an alley in Blue Island; Kiara Windom, of Harvey, 18, also strangled, was found in an alley on Chicago’s Southeast Side.

Pierce also is accused of killing Mariah Edwards, 17, whose lifeless body, prosecutors say, appears in a sex tape found on Pierce’s computer. Edwards’ body has not been found.

Pierce met his victims on phone chatlines or the Internet, and would sexually assault them before killing them, authorities said.

Attorney Nicholas Albukerk, who represents Pierce on the sexual assault charges, asked a Cook County judge on April 28 to put Pierce into protective custody while he’s being held without bail in the jail. The request was granted by that afternoon, sheriff’s spokeswoman Liane Jackson said.

Another serial killer abusing technology. Not that I think he would not have killed without it.

Sonny swears to his mom that he did not kill anyone but DNA tells a different story.

He was also a suspect in a death by neglect case when his girlfriend’s son died.

The Blue Island man charged with slaying three teenage women was investigated last summer but never charged in the May “death by neglect” of his girlfriend’s toddler son.

By the time Sonny Pierce, 27, was arrested in August — for allegedly raping a 15-year-old girl — he was being investigated but had not been charged in two other slayings as well as the boy’s death, according to court records and authorities.

Pierce, who allegedly strangled two of his victims, told investigators that 17-month-old Jordan Woods had choked inside his apartment, according to a source with knowledge of the case

The toddler was reaching for him, Pierce told authorities, but he ignored the boy because he thought he only wanted attention, the source said.

Pierce’s mother, Esther Pierce-Pearson, said Jordan passed out after suffering from high blood sugar linked to a diabetic condition. The night Jordan died, she said she heard a commotion in her son’s apartment and found him trying to resuscitate the boy.

Jordan had previously suffered a broken leg, the source said, an injury that Pierce attributed to the boy getting his leg caught in a playpen. Pierce’s mother said Thursday that the boy had also had his leg mauled by a dog.

Jordan died May 7 at MetroSouth Medical Center in Blue Island. An autopsy found the cause and manner of death were inconclusive, according to the Department of Children and Family Services. A worker at the Cook County medical examiner’s office said she could not find their record of the case.

DCFS ruled in September that there was credible evidence against Pierce of death by neglect, an agency spokesman said.

A spokeswoman for the Cook County state’s attorney declined to comment on why charges never were filed. Calls to Blue Island police, who also investigated Jordan’s death, were not returned.

Two months after Jordan died, Pierce allegedly raped and beat to death a neighbor, 17-year-old Mariah Edwards, then put her body in a garbage bag. Her remains have not been found, but police recovered a video from Pierce’s computer of him allegedly having sex with her seemingly lifeless body.

Authorities found additional videos on Pierce’s computer, which was analyzed at an FBI lab in Chicago, but have not yet determined if there were other victims. Pierce told authorities he went online to date and meet other women after he was questioned in the first two murders, records show.

What a winner.

Police Hoping That Familial DNA Can Help Catch Another Serial Killer

Daytona Beach Victims

Daytona Beach’s top cop believes new DNA technology will help his department catch the serial killer who has eluded police since 2005.

Familial DNA has helped police in California nab the so-called Grim Sleeper serial killer.

He was called that because he lay dormant in between murders for 18 years.

“We’re extremely interested in this because of our serial killer. Our serial killer may have an offspring, which is in the database,” said Daytona Beach Police Chief Mike Chitwood.

Police in California had DNA of the Grim Sleeper in a nationwide database.

The killer is responsible for the deaths of 10 women dating back to the 1980s.

New software emerged that tracks DNA of the killer’s family members, in this case his son, who was arrested on an unrelated crime.

Investigators used the information and followed the father, Lonnie Franklin, 57.

They took a DNA sample from pizza Franklin had recently eaten, made the exact match and then arrested the former garage attendant.

The Daytona Beach serial killer left behind DNA samples inside three of the four women he raped and killed.

The first was Laquetta Gunther, 45, who’s body was found on Beach Street on Dec. 26, 2005.

On Jan. 14, 2006, the body of Julie Green, 34, was found in a construction site off of LPGA Boulevard.

Iwanna Patton, 35, was found on Williamson Boulevard six weeks later on Feb. 24.

The killer then laid dormant for two years.

Twenty-year-old Stacey Gage’s body turned up Jan. 2, 2008 in a wooded area on Hancock Boulevard.

The DNA sample was turned over to Florida Department of Law Enforcement where it waits for a perfect match.

But Chitwood wants to use familial DNA to track down the serial killer’s family members, which in turn could lead back to the killer.

However, familial DNA is only approved in states like California, Colorado, and recently in Virginia. It has been used in Great Britain for several years.

Chitwood is working with the State Attorney’s Office, who is trying to convince both the state attorney general, as well as Gov. Rick Scott to sign off on it for use in Florida.

The police chief said familial DNA would only be used in major crimes, like the serial killer case.

He believes that if approved, it could be in use within a year.

Chitwood said the person who came up with the software is making it available to FDLE for free.

But he said the clock is ticking.

“You have a killer on the loose who has killed four women, who is not gonna stop,” Chitwood said. “We may be in a cooling off period here. But if we have learned anything in the history of this country with serial killers, they’ll continue until they get caught.”

I am all for the use of familial DNA especially in cases involving serial crimes. I do not know why people worry so much about using it. It helped to catch the Grim Sleeper, Lonnie Franklin and DNA has helped to link unknown victims to their killers. I think we need to give law enforcement all the help that we can.

Richard Ramirez dna linked to dead 9 year old girl. Her name is Mei Leung

 

SAN FRANCISCO — It took 11 months, but the DNA of infamous “Night Stalker” Richard Ramirez has finally been retested, allowing police to close the case of the 1984 murder of a 9-year-old girl in the Tenderloin.

Pera said the turnaround time for DNA tests — crucial work in solving long-cold cases — is still as slow as ever.

“The lab is still very understaffed,” she said. “There’s still only a few people that do the DNA analysis.”
