For those struggling with this bug I was able to work around it by shift clicking on my sim and using the pack cheat, debug arrest suspect. This at least generated sims on the lot though they did not look anything like the suspect description but through process of elimination I was able to arrest the correct sim and close the case anyway. Good thing this was my sims last day at work, he quit to become a stay at home dad. Geez of all the active jobs detective is the WORST, it’s the most bugged and the most repetitive, really not any better than a rabbit hole job
Thanks for the debug tip, I was tearing my hair out and I'm gonna try that right away. This bug has haunted me for days again - usually the suspect is always the first/only Sim in the lot, in my case this one Sim was always some rando not fitting the description and not being the right subject, last time even a toddler... and of course every attempt to arrest some random Sims just to try finding the right one by luck results in bad work performance.
