Toni Hartzong

The case went cold, but members of Tony's family were still troubled by some of Bob's behavior.

Like bringing a woman to his son's wedding just six months after the murder.

And while some who knew Bob found it hard to believe he was capable of murder... Did you ever see Bob Hartzong angry?

Never.

No, no.

I never really saw him raise his voice.

Never violent?

Nope.

Others say Bob had a mean streak.

He gets out of the car, he walks up to me, and he says, I hate the bitch.

Steve Kachakian says Bob once referred to Tony that way while Kachakian was working for Bob.

He says he saw Bob's temper another time, directed at him over a minor business matter.

I've never seen anybody get so angry at anybody.

I've been a bouncer.

I mean, I've seen people angry, but never like this.

But with the case at a standstill, Bob was moving forward with his life.

Two months after the murder, he bought a motorcycle, he sold his business a year later, and he started dating.

Susie Goldstein, who owns a marketing business, met Bob through an online dating service in 2002.

Tell us about Bob.

What kind of man is he?
