May 2nd, 2001 was 25 years ago, but Linda Lyle still remembers what the weather was like that day.

Back then, Linda was working at an advertising company on the edge of Washington, D.C.

It was a small office, and Linda knew all her colleagues by name, including a woman named Leslie Prier.

Leslie helped with the administrative side of the business.

She'd been with the company for four years.

She was in her late 40s, but looked a lot younger.

A classic, Grace Kelly-esque beauty, with dark hair and fine features.

But on this particular spring morning in 2001, Leslie was not at work as scheduled.

She didn't show up.

This was a problem from a business perspective.

It was Leslie's job to mail invoices.

If no invoices went out, no money was coming in.

Brett Reedy was the operations manager in the office.

He was also Leslie's boss.

Brett had recently had a talk with her about punctuality.

Leslie lived nearby, just a few miles away, but she'd been turning up late a lot.

So when 10 a.m.

came and went, Brett took notice.

Brett Reedy is a pretty even-keeled guy.

But Leslie's absence that day, it clearly got his attention.
