I don't like playing careers too often because I suck at them, but I have one Sim who is in the detective field. I'm really struggling. He has yet to solve his first case. I go to crime scenes, take photos and gather evidence. I talk to witnesses. What more am I supposed to do? His career path says he needs to interrogate a suspect, but I haven't got a clue how to find a suspect. Are there any tutorials or websites that can help me figure out how to advance in this career?
