My understanding of Spanish Law is as follows:
14 is usually the age of criminal responsibility.
Menores de edad from 14 to 18 can only be given a maximum sentence of two years in prison per crime.
What would happen if a 14 year old minor did a serious crime, for example murder, but the police only discovered the crime and arrested the person when they were 26? Would they get two years, or tried as an adult where the sentence is much longer?
