Offending profiles of individuals with autism spectrum disorder: A study of all individuals with autism spectrum disorder examined by the forensic psychiatric service in Norway between 2000 and 2010.
Forensic adults with autism usually know their victim, stay sober, and confess, but no single offence pattern exists.
01Research in Context
What this study did
Helverschou et al. (2015) read every forensic file in Norway for people with autism from 2000-2010.
They wrote down who the person hurt, how they did it, and whether drugs or drink were involved.
What they found
Most offenders already knew their victim.
They rarely used drugs or alcohol and usually confessed when caught.
There was no single “autism crime type”; the acts looked very different from person to person.
How this fits with other research
Boylu et al. (2025) later studied Turkish forensic cases and added a non-autism control group.
They saw more sudden, unplanned acts against strangers and more social-media offences than Berge found.
The difference is likely method: the Turkish team compared groups, while the Norwegian team simply described their cases.
Petrovic et al. (2016) and Ekas et al. (2011) remind us that adults with autism also carry heavy medical loads—seizures, obesity, high lipids—so health screening remains vital alongside risk assessment.
Why it matters
When you work with an adult client who has autism and legal trouble, expect a calm interview, little substance use, and a ready confession.
Still, probe for impulsive acts and online behaviour; newer data show these can surface.
Use the picture to plan safety and support, not to stereotype.

03Original abstract
This study examined the characteristics of adults with autism spectrum disorder who have undergone a forensic examination and explored any relationships between the diagnosis and the offence. The reports described 41 men and 7 women. The autism spectrum disorder was diagnosed late (mean age: 25.3 years), and 22 of the 48 cases were diagnosed with autism spectrum disorder for the first time by the forensic experts. The education level and employment status were low. Family networks were close, but social networks outside the family were limited. Co-morbid diagnoses were common, and more than half of the group knew their victims. The examined individuals constitute a vulnerable and heterogeneous group, as do offenders within other diagnostic categories. Unlike most others who commit criminal acts, the majority of the individuals with autism spectrum disorder in this study showed no evidence of substance abuse, had a close relationship to their victims and were willing to confess to the accused crime. No clear association between the characteristics of autism spectrum disorder and the criminal act were identified, but in most cases, autism spectrum disorder characteristics, such as idiosyncratic comprehensions and obsessions appeared to be related to the motive for the offence.
