well you will need to create two tables and create a relationship between them
first table will be :
Name_Victim
Age_Victim
Sex_Victim
Second table will be :
Perpetrator_Name
Age_Perpetrator
Sex_Perpetrator
where they have to be connected to a unique ID between both of the tables ( its very important )
in order to make relationship between both of the table you need to create a unique identifier to both tables
hope that helps
