Dr. Timothy Stryker

I always knew that I was going to be a doctor.

My father's a doctor, my mother's a nurse, so it was always in my blood to be a doctor.

I never questioned it.

One of my attractions to Linda was that she was in a similar situation of being a very dynamic person with a very busy practice.

I respected so much how she went that extra mile to really take care of her patients and do everything that needed to be done to help a mother have a healthy baby.

We would go jogging together, and we had dinners together.

We had so much to share and so much compatibility.

We did speak on the phone that evening that she died because she stayed at the hospital.

She had phoned me to tell me she wasn't coming over for dinner that night.

It was that kind of stunned, shut down, everything else sort of seemed a little bit more like a twilight zone around me.

They started going to this good cop, bad cop routine.

And I knew at that point I was clearly being played.

With the evidentiary trail that we developed over the last 15 years, Timothy Stryker remains a suspect.

I know that I'm innocent here.

Did the doctor kill the doctor?

Tonight's 48 Hours Mystery.

Depending on whom you believe, Dr. Timothy Stryker is either a calculating murderer or he is an innocent man desperately trying to clear his name.

I've spent hours just sitting and thinking, you know, how could people think that I could be guilty of something like this?

To look at him today at age 56, you'd never know Dr. Stryker has spent 15 years dogged by such terrible suspicions.

It just makes me sad that people could think this way about me.
