In 1991, a high school girl vanished after attending a party.

Her abandoned vehicle was found in a school parking lot near her home.

The prime suspect had not one but two alibi witnesses for the night she disappeared.

A solid alibi can often overcome much circumstantial evidence.

But forensic evidence is another matter.

The United States... On a Saturday night in November of 1991, Todd, on a Saturday night in November of 1991, 17-year-old Crystal Fade Todd was dropped off in a mall parking lot after attending a party.

Since Crystal didn't have to be home for another hour,

she said she was going to get something to eat before heading home.

It was the last time Crystal was seen alive.

When she wasn't home by 1 a.m., her mother contacted police.

She also called Crystal's best friend, Ken Register, who said he hadn't seen Crystal all night.

After I talked to Ken Register, I called him one of my friends, and he got up out to bed and

come in.

We went all over Conway hunting her, see if we could find her car anywhere.

They found her car the next morning in a nearby school parking lot.

Her purse and coat were inside.

I don't know why I meant I had to feed it.

It's just something come over with me that somebody had Crystal.

17-year-old Crystal Faye Todd was a senior in high school living in the small tobacco

farming town of Conway, South Carolina.

I was 39 and she was born.

She was a miracle to me.
