Welcome back to postmortem. I'm CBS News correspondent Jonathan Vigliotti, filling in today for Anne-Marie Green.

And joining me is 48-Hours producer, Michelle Finucci, to discuss our latest report on the murders of Christy Giles and Hilda Cabrales, two friends who went home with David Pierce after a night out in Los Angeles in 2021.

Pierce and his roommate, Brandt Osborne, took the women to two separate hospitals the following evening.

Both women had elevated levels of fentanyl in their systems, and tragically,

they both ultimately died of drug overdoses. Both Pierce and Osborne denied involvement in their deaths.

At trial, Pierce was also charged with rape for seven Jane Does, and they testified about Pierce's

pattern of violent sexual assault. Michelle, thank you for joining us.

Thank you for having me. Before we get started, a reminder, if you haven't listened to the 48 hours

episode yet, you can find the full audio just below this episode in your podcast feed. So go take a listen,

then come back here for our conversation. Michelle, you have been covering

this case from the very beginning. Our first 48 hours episode, I believe, aired nearly two years ago.

This was before Pearson Osborne's trial. And I wonder, and I imagine a lot of listeners and viewers

want to know the same, what has it from your perspective been like to watch this case develop

over the years?

This is a case that started just as a, you know, a headline of two women dropped at

separate hospitals.

We really didn't know if it was just a drug overdose case, a tragic drug overdose.

But about six days into this, I met with

Jan Sillier, who is Christy's husband. He looked at me in the eyes and he said, trust me,

this is foul play. You know, I know my wife. I know something happened. He said,

I know they were held against their will in that apartment.

And he was right.
