This segment always scared me after I first saw it 0__0. From what I recall a man (I think he was a cop) was standing in his kitchen (this was I think in the 50s, 60s or 70s lol) and someone from outside shot him and I'm pretty sure killed him.

Any idea what this segment was called?

I also think this is probably the Probst case. Here's a link to the wikia summary of the case:

Here's another one where a cop was shot through his kitchen window:

Sounds like Ralph Probst to me.
