I've never had any problems finding the suspect. I don't even need to know their traits. I haven't been wrong even once. I just put the hints together and then I look around at the lot. They usually fits the descriptions pretty accurate. I usually only need 5 clues and I haven't made them introduce themselves either. My sim is now chief of the police. She has solved a lot of cases :D It's really pure logic.
To the person who had a suspect with a Leia costume. The hair is considered a hat, so underneath the sim was probably still blonde. Bald sims is still considered having hair so...
