I was watching a video earlier that said the detective that is involved in the case has been looking at cases in Louisiana and other states. apparently the suspect had traveled to a few places after they talked to him in the 70's. They recently talked to him again in 2018.
They also said in the video that a person at highland hospital named the same man and they were sure he had committed the crimes. It seems his Psychiatrist gave the police information saying he had admitted in therapy to the crimes. The new detective was trying to get the notes from Highland Hospital. The suspect told the police that he "used to be a certain way" years ago but changed. He refused to say anything else. The detective said he was now living as an openly gay man. The video was about 45 minutes long but had a lot of information.
