Christopher Tapp

No, I didn't murder that girl?

But if Tap's friends thought they were being tortured, Angie's mom, Carol, was living in her own personal hell.

That's when I went to the streets and I literally put 60,000 miles on my truck searching for her killer.

I distributed like 1,200 flowers through the summer.

Did you go to scary places, dangerous places?

Oh, yes.

And I remember going to a place and the lady said,

said, you know, you need to leave before somebody hurts you.

And yet she kept doing it for years, taking incredible risks.

I had a gun put to my head one night.

And during those nights, Carol often ended up parked outside the apartment where Angie was murdered.

I would just stare at that house and stare at the windows and try and figure out how scared she must have been.

She also endlessly is, is talk the right word?

Those friends of Chris Tapp, like Jeremy Sargis.

There was times I would be working, look up, and there she is.

That's Detective Jared Furman, of course.

Carol prodded him.

Proud of them, the whole department insisting they keep searching for the killer for more than a decade.

She spent her days and nights reading police reports, practically memorizing them.

I don't sleep and I get up and I just go, what part of this don't I understand?
