He thought deeper.
He had long suspected that Pari Jones had some clues unknown to the police.
Now it seemed that Luke had underestimated her.
If it was merely witnessing Nicole's victimization, Pari Jones should not have been able to find out Nicole's identity.
According to Laura's description, Nicole was carrying a black backpack the night she was killed, but the police never found that backpack.
Pari Jones likely obtained the items from the victim's backpack, thereby finding Nicole's home address.
Taking evidence from the crime scene was illegal.
Of course, these were all Luke's conjectures; to arrest someone, he still needed solid evidence.
A few minutes later, Pari Jones came out of Nicole's house and got into the news station's car and left.
Luke and another person entered Nicole's home and asked her father some questions.
As Luke had guessed, Pari Jones was there to investigate the matter at Dracula Bar.
