Sam Parker

The 911 dispatcher, who had helped so many people in crisis, was dealing with a very personal crisis of her own, an angry and abusive husband.

I think she hid it very well.

I think she hid it from everybody.

Did Sam have a drinking problem?

What was he like when he drank?

Funny?

Teresa's sister Christina says there was nothing funny about her brother-in-law when he had too much alcohol.

He became a violent, mean drunk.

He would keep a water bottle in the refrigerator during family dinners or whatever, and he would sneak over there and drink out of this bottle, and it was straight vodka.

I had seen him in action, you know, so scary.

There have been allegations that you've had some issues with drinking.

So you did drink, but it didn't affect your job?

Is that fair to say?

That's very fair to say, yes.

Christina says Sam Parker's behavior could change from nice to nasty in an instant.

They had went out to eat for dinner one night.

And of course, he started out drinking.

Christina says when her sister left the restaurant, Parker followed her.

They got into the car, and he started threatening her.

Took his gun out, was shooting his gun up in the air in the parking lot.
