On January 24, 2025, 14-year-old Mattia Ahmet Minguzzi was fatally stabbed in Istanbul’s Kadıköy district. Reports indicate that a dispute erupted between Mattia and two other teenagers, identified as B.B. (15) and U.B. (16), at a local street market. Witnesses and surveillance footage show that as Mattia attempted to walk away, B.B. stabbed him five times. U.B. allegedly continued to assault him after he collapsed.
Mattia was taken to a nearby hospital with life-threatening injuries. He fell into a coma and was declared brain-dead the following day. He died on February 9, 2025.
Both B.B. and U.B. were arrested shortly after the attack. Prosecutors have charged them with murder.
The killing of a 14-year-old in broad daylight shocked Turkey. Social media platforms and news outlets filled with expressions of grief and demands for justice. Mattia’s mother, Yasemin Akıncılar Minguzzi, spoke publicly in a televised interview:
“A killer is a killer. A monster is a monster. You cannot call these boys ‘children.’”
She pledged to pursue justice for her son and insisted that those responsible must be held fully accountable.
Mattia’s father, Andrea Minguzzi, an Italian chef living in Istanbul, expressed profound grief and urged authorities to take action to prevent similar tragedies.
The case became a focal point for public anger when hashtags calling for justice for Mattia spread rapidly online. A Change.org petition titled “Justice for Mattia Ahmet Minguzzi – Let His Killers Receive the Harshest Punishment” collected over 150,000 signatures within days. The petition also called for legal reforms, including the removal of age-based sentence reductions in cases of aggravated murder and greater accountability for the parents of underage offenders.
On April 10, hundreds gathered outside the Istanbul Courthouse during the first trial hearing and chanted “Justice for Ahmet!” and “No More Murderers in Our Streets!”
At a recent concert, Kaan Tangöze, lead singer of the band Duman, paused to address the crowd:
“It wouldn’t be right for those who committed this attack to just be released like that. They need to face justice as well. Because they say, ‘they’re underage, they’ll be out soon.’ I mean, that’s not justice. Let me just say that.”
Juvenile Justice Under Scrutiny
The case has reignited ongoing debate in Turkey over juvenile justice, criminal responsibility, and sentencing for minors.
Under Turkish law, individuals under 18 are classified as childre. This status automatically reduces their sentences, even in cases of violent crime. Lawyers explain that a 15- to 18-year-old convicted of murder typically receives a sentence of 12 to 15 years instead of life imprisonment.
Prosecutors are seeking up to 24 years in prison for the two suspects. However, lawyers warn that, under current regulations, both could be eligible for parole in less than a decade.
Many argue that the law fails to adequately address the severity of crimes committed by older minors, and it is more and more unacceptable in cases of extreme violence.
Political Response and Calls for Reform
The issue has dominated discussions in the Turkish Parliament. MP Çiçek Otlu proposed the establishment of an investigative commission to examine youth violence and juvenile crime.
Saadet Party Vice Chair Mustafa Kaya supported the family’s demands and advocated for the removal of age-based leniency for minors convicted of serious offenses.
In March, President Recep Tayyip Erdoğan met with Mattia’s parents, offered his condolences and assured them that the case would be closely monitored. Following the meeting, AK Party MP Pervin Tuba Durgut announced that lawmakers had begun drafting legislative changes concerning juvenile offenders.
Durgut acknowledged that the current system categorizes minors accused of serious crimes as “children in conflict with the law,” and this classification often results in lenient sentencing.
International Attention and Human Rights Considerations
Mattia’s dual Italian-Turkish heritage drew significant international media coverage. Italian newspapers such as La Repubblica and Corriere della Sera reported extensively on the case and described Mattia as a boy “stabbed to death in a marketplace in Istanbul” while shopping for skateboarding equipment.
British outlets, including The Mirror and Yahoo News, also covered the story and questioned whether Turkey’s legal system adequately addresses violent crimes committed by teenagers.
The tension is rising between international norms on juvenile justice and the growing public demand in Turkey for stricter penalties.
A Case That Challenges Legal and Ethical Boundaries
The murder of Mattia Ahmet Minguzzi has exposed divisions over how society should respond to violent crime committed by minors.
Public sentiment in Turkey is that the current legal framework does not always serve the interests of justice. The debate is about how a legal system can both rehabilitate young offenders and address the trauma inflicted on victims and their communities.
For many, the case demonstrates the need for a careful reconsideration of how the law treats minors who commit serious crimes without abandoning the principle that children deserve support, education, and the opportunity for rehabilitation.
