Answer:
4. The husband of Euler Philip was a violent abuser and alcoholic
5. There were blood prints that didn't match with Philips husband's
6. Same weapon were used to perpetrate the crime.
explanation:
4. The husband of Euler Philip was a violent abuser and alcoholic (evidence that he committed the crime). Philip's husband was also attacked that night because he was covered with blood but the person that slept in between them was unharmed (Evidence that the husband didn't kill her).
5. These were the work of the first serial killer because there were blood prints that didn't match with Philips husband's and the husband stated outrightly that he would have killed his wife if he had known she was cheating on him.
6. The same weapon was used to perpetrate this heinous crime(axe) and the victims were mostly women who were sexually assaulted in most cases. These were the likelihood of the crime being executed by same person.
