Most murders are committed by someone the victim knows.
Yes, about 85-90 percent globally. This is why small police departments start any homicide investigation by grilling the people who knew the victim. Most of the time, somebody knows what happened. They know that someone had a reason to commit the murder. If the police can get that story, they often can solve the case.
But Amanda did not have a reason to kill Meredith. Raffaele certainly did not. In fact, nobody did. This was one of the 10-15 percent of murders in which the victim had no relationship with the perpetrator. That is evident in the forensic evidence as well as the nature of the crime scene.
But the cops didn't stop to think about the nature of the crime scene, and they didn't understand its significance. They followed the one and only approach they do understand, a rough heuristic driven by the factoid you cite here. It led to a spectacularly wrong answer. They did the same thing with the Michael Morton case in Texas, and with the Suzanne Jovin case in New Haven, CT, a murder that has never been solved. This is the cause of many wrongful convictions.
