In January, Lina went to the police.
Her ex-partner had been threatening her at house within the Spanish seaside city of Benalmádena. That day, he’d allegedly raised his hand as if to hit her.
“There had been violent episodes – she was scared,” Lina’s cousin Daniel recollects.
When she received to the police station, she was interviewed and her case registered with VioGén, a digital device which assesses the probability of a girl being attacked once more by the identical man.
VioGén – an algorithm-based system – asks 35 questions in regards to the abuse and its depth, the aggressor’s entry to weapons, his psychological well being and whether or not the girl has left, or is contemplating leaving, the connection.
It then data the risk to her as “negligible”, “low”, “medium”, “excessive” or “excessive”.
The class is used to make choices in regards to the allocation of police sources to guard the girl.
Lina was deemed to be at “medium” threat.
She requested for a restraining order at a specialist gender violence court docket in Malaga, in order that her ex-partner could not keep up a correspondence along with her or share her dwelling area. The request was denied.
“Lina needed to alter the locks at her house, so she may reside peacefully along with her kids,” says her cousin.
Three weeks later, she was useless. Her accomplice had allegedly used his key to enter her flat and shortly the home was on hearth.
Whereas her kids, mom and ex-partner all escaped, Lina did not. Her 11-year-old son was extensively reported as telling police it was his father who killed his mom.
Lina’s lifeless physique was retrieved from the charred inside of her house. Her ex-partner, the daddy of her three youngest kids, was arrested.
Now, her dying is elevating questions on VioGén and its capability to maintain girls protected in Spain.

VioGén did not precisely predict the risk to Lina.
As a girl designated at “medium” threat, the protocol is that she could be adopted up once more by a nominated police officer inside 30 days.
However Lina was useless earlier than that. If she had been “excessive” threat, the police follow-up would have occurred inside per week. May which have made a distinction to Lina?
Instruments to judge the specter of repeat home violence are utilized in North America and throughout Europe. Within the UK, some police forces use DARA (Home Abuse Danger Evaluation) – primarily a guidelines. And DASH (Home Abuse, Stalking, Harassment and Honour-based Violence Evaluation) could also be employed by police or others, like social staff, to evaluate the chance of one other assault.
However solely in Spain is an algorithm woven so tightly into police observe. VioGén was developed by Spanish police and teachers. It is used in all places other than the Basque Nation and Catalonia (these areas have separate methods, though police co-operation is nationwide).

The pinnacle of the Nationwide Police’s household and ladies’s unit in Malaga, Ch Insp Isabel Espejo, describes VioGén as “super-important”.
“It helps us observe every sufferer’s case very exactly,” she says.
Her officers take care of a median of 10 studies of gender violence a day. And each month, VioGén classifies 9 or 10 girls as being at “excessive” threat of repeat victimisation.
The useful resource implications in these circumstances are large: 24-hour police safety for a girl till the circumstances change and the chance decreases. Girls assessed as “excessive” threat can also get an officer escort.
A 2014 research discovered that officers accepted VioGén’s analysis of the probability of repeated abuse 95% of the time. Critics recommend police are abdicating decision-making about girls’s security to an algorithm.
Ch Insp Espejo says that the algorithm’s calculation of threat is normally enough. However she recognises – though Lina’s case wasn’t below her command – that one thing went mistaken with Lina’s evaluation.
“I am not going to say VioGén would not fail – it does. However this wasn’t the set off that led to this lady’s homicide. The one responsible occasion is the one who killed Lina. Whole safety simply would not exist,” she says.
However at “medium” threat, Lina was by no means a police precedence. And did Lina’s VioGén evaluation have an effect on the court docket’s determination to disclaim her a restraining order towards her ex-partner?

Courtroom authorities did not give us permission to satisfy the choose who denied Lina an injunction towards her ex-partner – a girl attacked on social media after Lina’s dying.
As a substitute, one other of Malaga’s gender violence judges, Maria del Carmen Gutiérrez tells us typically phrases that such an order wants two issues: proof of against the law and the specter of severe hazard to the sufferer.
“VioGén is one aspect I exploit to evaluate that hazard, nevertheless it’s removed from the one one,” she says.
Generally, the choose says, she makes restraining orders in circumstances the place VioGén has assessed a girl as at “negligible” or “low” threat. On different events she could conclude there is not any hazard to a girl deemed at “medium” or “excessive” threat of repeat victimisation.
Dr Juan Jose Medina, a criminologist on the College of Seville, says Spain has a “postcode lottery” for girls making use of for restraining orders – some jurisdictions are more likely to grant them than others. However we do not know systematically how VioGén influences the courts, or the police, as a result of research have not been completed.
“How are cops and different stakeholders utilizing this device, and the way is it informing their decision-making? We do not have good solutions,” he says.

Spain’s inside ministry hasn’t typically allowed teachers entry to VioGén’s knowledge. And there hasn’t been an impartial audit of the algorithm.
Gemma Galdon, the founding father of Eticas – an organisation engaged on the social and moral affect of know-how – says when you do not audit these methods, you will not know in the event that they’re truly delivering police safety to the appropriate girls.
Examples of algorithmic bias elsewhere are well-documented. Within the US, evaluation from 2016 of a recidivism device discovered black defendants have been extra probably than their white friends to be incorrectly judged to be at larger threat of repeat offending. On the similar time, white defendants have been extra probably than black defendants to be wrongly flagged as low threat.
In 2018, Spain’s inside ministry did not give a inexperienced gentle to an Eticas proposal to conduct a confidential, pro-bono, inner audit. So as an alternative, Gemma Galdon and her colleagues determined to reverse-engineer VioGén and do an exterior audit.
They used interviews with girls survivors of home abuse and publicly accessible info – together with knowledge from the judiciary about girls who, like Lina, had been killed.
They discovered that between 2003 and 2021, 71 girls murdered by their companions or ex-partners had beforehand reported home abuse to the police. These recorded on the VioGén system got threat ranges of “negligible” or “medium”.
“What we would wish to know is, have been these error charges that can not be mitigated in any method? Or may we have now completed one thing to enhance how these methods assign threat and shield these girls higher?” asks Gemma Galdon.

The pinnacle of gender violence analysis at Spain’s inside ministry, Juan José López-Ossorio, is dismissive of the Eticas investigation: it wasn’t completed with VioGén knowledge. “If you do not have entry to the information, how are you going to interpret it?” he says.
And he’s cautious of an exterior audit, fearing it may compromise each the safety of ladies whose circumstances are recorded and VioGén’s procedures.
“What we all know is that after a girl studies a person and he or she’s below police safety, the chance of additional violence is considerably lowered – we have no doubts about that,” says López-Ossorio.
VioGén has developed because it was launched in Spain. The questionnaire has been refined, and the “negligible” class of threat will quickly be abolished. And even critics agree it is smart to have a standardised system responding to gender violence.
In Benalmádena, Lina’s house has change into a shrine.
Flowers, candles and footage of saints have been left on the step. A small poster caught on the wall declared: Benalmádena says no to gender violence. The group fundraised for Lina’s kids.
Her cousin, Daniel, says everybody’s nonetheless reeling from information of her dying.
“The household it is destroyed – particularly Lina’s mom,” he says.
“She’s 82 years outdated. I do not assume there’s something sadder than to have your daughter killed by an aggressor in a method that would have been prevented. The kids are nonetheless in shock – they’re going to want a whole lot of psychological assist.”
