Saw this and thought of A&L. This is possibly how BG is eventually caught. I believe due to a new DNA felony collection law that recently went into effect.
This case is from Bloomington, IN:
13 years after Bloomington rape, police make arrest thanks to DNA evidence

BLOOMINGTON, Ind. –
Nearly 13 years after a Bloomington woman was raped in her own apartment, police say they’ve made an arrest, thanks to DNA evidence.
Police began investigating the case on the night of March 28, 2006, when officers responded to an apartment in the 300 block of East 2nd Street. That's where the victim reported she had been sexually assaulted.
On February 5 of this year, Bloomington police say they were notified by the Indiana State Police Laboratory that DNA evidence collected during this investigation had been matched to an offender in the Combined DNA Index System (CODIS) database.
A DNA sample had recently been collected from the suspect due to his arrest for a felony charge in Lawrence County in late 2018.
Once the suspect’s DNA profile was compared to unknown DNA profiles in the database, the system matched the suspect’s DNA with samples collected during the initial investigation in 2006.
