That's what I've always heard.

As that knife is penetrating the body, you are going to have cast-off blood.

It is messy.

You can actually smell the copper in the air from the blood flow.

So it is emotionally, you have to be really determined to stab somebody.

It's very easy to just pull a trigger and close your eyes from 20 feet away.

But a knife is personal.

And you have to keep doing it.

You have to keep doing it.

If you stab them over and over again.

And in this particular case, Amanda Plass was stabbed multiple times in her sides, both right side and left side, and through her heart.

Yes, and well, statistically, I'm going to tell you that about 80 to 85% of women who are murdered, the culprit is going to be somebody they know and know or knew intimately.

Boyfriend, husband, ex-husband, ex-partner, some kind of stalker, but somebody that they know, right?

It's very rare, only about 20% of the time, that it is an absolute stranger.

So the first thing we think is this is going to be somebody in her inner circle.

I mean, ultimately they cleared him, but... Yeah, when I first heard, wait, she has a boyfriend and he's a carpenter, he's a roofer, he has tools and utility knives.

I've got to tell you, statistically, Seth Green is your guy.

In most cases like this, the new boyfriend, the guy she's been dating for a week that she may not have known very well, may not have vetted, he is usually going to be the killer.

Even though he called police first to say that he had found her body.

Well, killers do that all the time.
