On one day in the late-game, you will receive an anonymous call to replace the fuel in your officers' cars with a special fuel. You will be given $12,000 and you'll never hear from this person again. I, stupidly and blindly, accepted this thinking nothing of it. It wasn't until a week later that the problems occur. Your officers will tell you about a strange sound coming from their car's engines. Then, after a few days you'll have the first "accident". Your officers will begin crashing on their way to calls and dying immediately. You'll then realise what a terrible mistake you've done. For the next few weeks to come, almost every day you will lose at least one officer thanks to this fuel. In one day, I lost 3 of my best officer (totalling to around 4000 experience points) thanks to them crashing their cars. These car crashes create a number of problems for you: you will most likely fail the call they were going to; you'll lose a great officer (most likely), and you'll have to hire new ones (who will probably be around 100-200 experience). At this stage you will have to do your best and pray that your best officer doesn't die. Furthermore, a lot of officers will stop going to work and skip it as it will be close to Christmas. So these days will be especially tough.
