A NURSE in Argentina has been sentenced to life in prison for ruthlessly murdering five newborns and trying to kill eight others.
The case bears chilling similarities to that of Brit baby murderer Lucy Letby, the nurse who is serving 15 whole-life sentences for killing seven babies and attempting to murder seven more.

Brenda Cecilia Aguero, 29, stole deadly doses of potassium and insulin before injecting them into newborn babies between March and June of 2022, prosecutors said.
Similarly, Letby was accused of injecting air and insulin into the babies, as well as overfeeding them milk - but has always maintained her innocence.
Many have cast doubt over Letby's convictions and others suggest she was targeted in a 'witch hunt'.
In the chilling Argentine case, newborns tragically died initially under unexplained circumstances in a maternity hospital in Cordoba province, north-west of Buenos Aires.
Baby killer Aguero tried to murder eight other babies between March and June of 2022, but they managed to receive rapid, live-saving medical intervention, local media reports.
The 29-year-old will serve at least 35 years in prison before being eligible for parole, under Argentine law.
Aguero's mum, Cristina Nobile, mainains her daughter's innocence and told reporters she would continue to press to have her conviction overturned.
She added: "My daughter is innocent, and I will continue fighting."
Prosecutors alleged during the trial that Aguero's motivation behind the wicked killings was to further her career.
They say that she attacked the newborns in order to be the first to notice their symptoms and consequently impress her bosses.
How Dutch Lucy Letby who was CLEARED over murder of seven patients, including babies, is 'key to freeing jailed nurse'
But with five newborns dying within such a short space of time, the country's Health Ministry launched a probe.
An alarming pattern was noticed, with babies having unexplained puncture marks in areas where injections weren't typically administered.
Toxicology reports revealed that several of the babies had potassium or insulin levels that they couldn't have produced naturally.
And prosecutors argued that Aguero was the only person present during all the harrowing incidents and has "exclusive proximity" to the mums and their babies.
Aguero denied the charges and told the court "they have no evidence".
She also accused the media of portraying her as a "serial killer".
Ten other defendants, including the former health minister in Cordoba as well as the former hospital director, were accused of attempting to cover up the incidents and destroy evidence.
Five were found guilty but received shorter sentences, and the five others were acquitted - including the former provincial officials, local media reported.

Killer nurse Lucy Letby was convicted of ruthlessly murdering seven babies in her care
The case bears chilling similarities to that of Brit Letby, now 34, who was last year given a whole life order in prison for the murders of seven babies and the attempted murders of seven more at Countess of Chester Hospital.
During her ten-month trial, which ended last August when she received a whole life sentence, it was revealed she injected her victims with air or insulin, overfed them and physically abused them with medical tools.
An application to appeal against her sentence was rejected in February of this year.
She was convicted across two trials at Manchester Crown Court of murdering seven babies and attempting to murder seven others.
The 35-year-old from Hereford is serving 15 whole-life orders.
She lost two attempts to challenged her convictions at the Court of Appeal last year.
Separately, Dutch nurse Lucia de Berk was found guilty of killing seven and attempting to kill three of her young patients in 2003 and 2004.
Just like Letby's case, prosecutors claimed the smoking gun evidence came from a string of 'sinister' diary entries — and hospital shift patterns which revealed she had been present at all of the deaths.

De Berk spent five years behind bars at Scheveningen prison before the case went to the appeal court and was acquitted in 2010.
During police raids on Brit Letby's home after her arrest, officers took a specific interest in her diary, as well as other notes found in her bedroom.
One such scrawling, which went on to form a key part of the case against her, said: 'I am evil, I did this.'
It was emblazoned on a bright Post-It, alongside another saying: 'I killed them on purpose because I'm not good enough.'
Her diary, meanwhile, found in a bedside drawer, was thought to have contained a sadistic trail of breadcrumbs.
These included coloured asterisks, as well as initials and words added to days that occasionally coincided with the dates of deaths or attacks she was later found guilty of.

Mystery female donor who paid £1,300 fine to free Madeleine McCann suspect Brueckner is former COP who investigated him

THE woman who has paid for the prime Madeleine McCann suspect's early release has been revealed as a cop who had been investigating the paedophile. The mystery donor settled a £1,300 outstanding court fine which means Christian Brueckner, 48, will walk free in less than three months, on September 17. Advertisement 6 The woman who has paid for Christian Brueckner's early release from jail has been revealed as a cop Credit: Dan Charity 6 Brueckner's release will have a major implication on the investigations into the disappearance of Madeleine McCann Credit: AFP Reports have now identified her as a former officer with the German FBI - known as the BKA - who claims to have been involved in wire-tapping his jail cell. She confirmed to respected Hamburg-based publication Der Spiegel she paid the funds directly to the justice system - allowing the fiend out early. Watch The Sun's exclusive documentary on the Maddie case here Convicted rapist Brueckner had only been able to pay off £210 of the total fine and faced being kept behind bars until January. Advertisement That scenario would have granted cops four precious extra months to hunt down forensic evidence and finally charge him over Maddie's disappearance. As it is, the ex-cop's intervention undermined the same force she previously worked for - all as they tirelessly dug for new clues in Portugal two weeks ago. The woman - who has not been publicly named - claims she worked in the field of 'Operative Technology Audio'. She says she was involved in bugging Brueckner's prison cell - allegations that emerged in court last year as the disturbed German was cleared of fresh rape charges. Advertisement The female fine-payer did confirm: 'I never had personal contact with Christian B.' And when confronted over the fine payment, the woman bizarrely told Spiegel it has been a 'misunderstanding' and she had tried in vain to reverse the payment. She reportedly believed the fine was due to Brueckner insulting a police officer, something she said "wasn't justified". Madeleine McCann: the secret evidence on prime suspect Christian B | Sun Documentary When she learned that the penalties were actually to do with a number of infractions, including bodily harm, 'it was already too late,' she said. Advertisement Spiegel reports it has been able to verify she transferred £1,300 to an account of the Braunschweig public prosecutor's office at the Comdirect bank. It cleared a 2016 Helmstedt District Court fine for drunkenness in traffic and forgery of documents and a 2017 Braunschweig court levy for assault. Brueckner will now walk free when his sentence for raping an American woman, 72, in Praia da Luz, in 2005, ends. He has been named publicly as the prime suspect over the May 3, 2007 disappearance of Maddie, of Rothley, Leics., since 2020 but has never been charged. Advertisement He has used letters to deny the claims but has refused to answer police questions or provide an alibi. His phone was in Praia da Luz on the night Madeleine vanished and made a 30-minute call from the area. 6 Young Maddie vanished on May 3, 2007 in Portugal Credit: Alamy 6 Brueckner appeared in court earlier this year over verbal assaults on prison guards Credit: Rob Pattinson Advertisement His Jaguar was re-registered into a name the day after the disappearance.

February 16, 2024 Brueckner goes on trial accused of none-McCann allegations of rape and sex assault, in Braunschweig, Germany.

Dutch footballer Quincy Promes 'extradited to the Netherlands to serve over SEVEN YEARS in prison' for drug trafficking and stabbing brother - but taxpayers 'have to pay for the flight!'

Dutch footballer Quincy Promes has reportedly been extradited back to the Netherlands to serve a seven-and-a-half year sentence for drug trafficking and aggravated assault. Promes has been playing his football in Dubai but was seized by the authorities after a request by the Dutch police. The former Ajax and Netherlands star, 33, was hit with a six-year jail sentence in February 2024 after being convicted of helping to smuggle cocaine into his homeland from Belgium in 2020. That followed an 18-month sentence for stabbing his cousin, but he has been absent from the Netherlands and therefore not served any time. Dutch outlet De Telegraaf reports that Promes begins his sentence in a detention centre after being flown back in a chartered plane. His plane cost almost £86,000 to the taxpayer after it was demeed there were 'safety risks' in putting him on a public flight. Premier League giants such as Liverpool and Arsenal were linked years ago with a move for Promes, who has won trophies in the Netherlands and Russia and earned 50 caps for his country. The earliest Promes will be released is in 2030 if his sentences are upheld wth parole, reports De Telegraaf. The Amsterdam court ruled last year that Promes had been directly involved in smuggling 1,360 kilograms of cocaine to the Netherlands or Belgium in two shipments in 2020. Promes denied the charges but the court found there was enough evidence from two eyewitnesses and intercepted phone conversations to hand down a prison term. Meanwhile, in the incident with his brother, the stabbing to the leg occurred at a family party at a warehouse in Abcoude after Promes got into an argument over a stolen necklace. He was playing in the Netherlands for Ajax at the time but moved to Spartak in February 2021. The judge criticised Promes, who is currently in Russia, for not coming to the court to defend himself or expressing any remorse. His sentence would have been six months less had he done so. Podcast All episodes Play on Apple Spotify The Dutch authorities have not been able to lock him up due to the fact he has been playing in Russia and Dubai until now. The Amsterdam-born forward played 50 times for the Dutch national team, scoring seven goals. Starting his career at Twente, he had a four-year stint with Spartak between 2014 and 2018 before signing for Spanish club Sevilla. From there, he spent a season-and-a-half with Ajax before returning to Spartak. He has scored 37 goals in 74 games for the club during his second spell. He joined second-tier Dubai United for last season and scored 19 goals in 20 appearances.
