That DM article - quote from Aimee
"because of the impact my role has on my family and the survivors of my father’s criminal behaviour".
That directly implies further victims.
DC was as we've all seen, involved with gymnastics club, scouts, also various charities, parkrun, prominent upstanding member of society etc
Generally it would be very unusual for a criminal of this type to go from nothing to the extreme crimes he was convicted of.
Common sense says that there must be more victims.
Aimee seems to say that as well?
