Back in the late 90s there was a brutal multiple victim murder where some random guy walked into the back of a local restaurant before it opened and killed everyone in the kitchen. Some TV station did a true crime story on it where they changed the all the names but the local police had a copy and knew it was that story. I kind of realized then that they just pull the subject case out of a hat and slap on The Voice, a camera filter, and follow the formula of tense interviews and add breaks.

Fargo was a lot of fun

I used to work with sometime who's apartment was regularly requested to be used to shoot scenes for some movie or show or another. She got paid while they filmed inside for a few days.

Fortunately not serial killers, but the HBO documentary Telemarketers (good watch, highly recommend) was shot in NJ, and I saw many locations very close to my home. Always neat to see.

I watched Don't Fuck With Cats, the documentary about Luka Magnotta and the murder he committed. I had just moved back to my hometown after being away for some 15 years. I wasn't familiar with what had happened but knew the name and confused him with the guy that stabbed an Asian man to death in the back of a bus around the same time. I was very very confused when I started to see drone shots of my neighborhood at the start of the second episode, seeing my morning bus stop and post office currently and then discovering that the place where the body was left was one of the spots I used to play at as a child.

It was a wild discovery.

I hate seeing anything at all about Dahmer because i personally know some of the victim's families

had this happen kinda nearby where an employee of a small haircuts place decapitated her boss

I met one not long before he was captured. Dude was singing karaoke with a victim at a bar. We were booing him because the girl did not look like she wanted to be there.
She later got away and he got caught.

Never had my neighborhood on a cop show, but I have lived near multiple school shootings. Does that count?
