Nice game!
I had a lot of fun with it, although I really wish I had diagonal movement, and the collision felt really precise for going through doors and such, which didn't seem necessary for this style of game!
I also wish there was more to the story, the actual murder case felt a little barebones, but I guess it's probably kinda tough to write a fully-fledged, interesting murder case while also programming a game in just 48 hours.
Also, you can easily cheese the car chase at the end by just cutting through the gravel. It wasn't super clear that I was supposed to just smash into her car, so I got in front of her several times, but didn't "win" the game and had to restart.
And the music loop was /very/ repetitive.
I absolutely adored how much flavor the game had though! I went and clicked on every single interactable item I could, just to see what flavor text would pop out!
All in all, a fun experience. Great work!
