Probably...
Aha. Thanks for the follow-up info.
So the guy has an intake photo at a Correctional Institute in June 1968, and the young woman is murdered on Jan 9, 1969, meaning he must have been released not long before the murder. Depending on his prior offenses, a recently released con should have been a suspect... I’m going to be unfair and wonder whether competent policework might have solved the case 49 years ago and saved the subsequent victims.
