A comparison of partner and solo arsonists

Area of Science:

• Criminology
• Forensic Psychology
• Sociology

Background:

• Arson is a serious crime with significant societal impact.
• Understanding offender typologies is crucial for effective intervention and prevention strategies.
• Previous research has explored various factors associated with arson, but the role of a partner has not been fully elucidated.

Purpose of the Study:

• To investigate the differences between partner and solo arsonists.
• To examine the relationship between the presence of a co-offender and offender characteristics.
• To explore how the social functioning, mental impairment, and criminal history vary between these two groups.

Main Methods:

• Systematic data collection on 225 adult arsonists arrested over a four-year period.
• Analysis of 83 variables pertaining to the arsonist and the specific arson offense.
• Comparative analysis of partner arsonists versus solo arsonists.

Main Results:

• The presence or absence of a partner clearly differentiated two distinct groups of arsonists.
• Partner arsonists and solo arsonists exhibited significant differences in social functioning.
• Variations in the burden of mental impairment and criminal history were observed between partner and solo offenders.

Conclusions:

• The partner variable is a key differentiator in understanding arsonist typologies.
• Offender characteristics, including social functioning and criminal history, are linked to the nature of the arson offense.
• This research highlights the importance of considering co-offender dynamics in the study of arson.
