juvenile crime

Juvenile crime is a common term for criminal acts committed by young people in their teenage years, and in a true crime context it covers cases where the perpetrator or defendant was a young person at the time of the offence. In Danish legal terminology, the legislation does not operate with juvenile crime as a fixed category; the relevant concept is instead youth crime (ungdomskriminalitet), and the formal rules take as their starting point the age group 10 to 17 years.

The age of criminal responsibility in Denmark is 15. This means that a person under 15 cannot be charged or convicted before the ordinary courts, regardless of the seriousness of the act. The police may nevertheless investigate the case, and other measures may be initiated. For young people between 15 and 17, special considerations apply in sentencing, and the responses will often be socially oriented rather than purely criminal-law based.

The central legislation in this area is the Act on Combating Youth Crime (lov om bekæmpelse af ungdomskriminalitet) from 2018, whose purpose under § 1 of the Act is to prevent youth crime through a dedicated Youth Crime Board (Ungdomskriminalitetsnævnet) and targeted measures for children and young people aged 10 to 17. The board can decide on preventive measures and serves as an alternative or supplement to ordinary criminal proceedings.

In an international true crime context — including in cases such as that of Sheila Eddy — juvenile crime is used more broadly and without being tied to a specific national age limit. What these cases have in common is that the perpetrator's young age plays a central role in the investigation, the trial and the public debate about responsibility, maturity and punishment. In many legal systems, age can affect whether a case is handled as a juvenile matter or an adult matter, and which sanctions are available.
