Every movie or show I seen there always something left by the Killer is that always the case for real life also?

It would be very hard to clean everything in the area you killed someone. Sometimes I'd assume there wouldn't be enough time to clean up anyways2

In real life, murder is one of the most difficult cases to solve, especially if they are a serial killer. Those kinds of killers usually don't have a link to the victims because they kill strangers. The ones that usually get caught are when they kill someone they knew because there is a more obvious motive so the detectives know where to look for the investigation.
Most TV shows and Movies are very unrealistic when dealing with this and the detectives are almost psychic to figure it out. Also, in real life, people that have killed don't just admit it so easily because a detective shouts at them or makes wild accusations, or attacks them in the interrogation room. Those detectives would be fired sometimes, or charged themselves.3
