Far be it from me to defend this criminal, but he hadn’t murdered anyone in the prior crime, so it is hardly “identical”.
Rape IS murder.
It is identical with respect to the sexual molestation of a child. The first time around should have put him behind bars for life.
Not the best written story—if the couple found “their grandparents” beaten to death their is an additional problem—his grandparents or her grandparents fine, by their grandparents—not good.
That is probably merely due to the physical resilience of the first victims rather than his “unwillingness” to commit murder.
The article says “almost identical”, which is was in almost every aspect: break in; assault of the adults; sexual assault of a child.
