Fatales Vertrauen - Dem Mörder so nah

I think the show is well executed and documented. However sometimes the facts are blurred. An example is how a 1985 case was solved using DNA which wasn't in use at that time. The only other thing that stands out is that seemingly every case is about the murder of a female. I say this because in every single show the producers will replay the victims screaming at least 15 times. There is always multiple suspects and they replay the screams with each one as they might have committed the crime as well as catch ups after commercials. In almost every case there were no I witnesses so there is no evidence there was any screaming to begin with. It may be a minor point to many people but it drives me to distraction.
