Do You Know Who the Killer Is?

Police are trying to put together kind of a profile in 1956 of who this person was. They feel like there aren't many signs of a struggle either in the car or on Dwayne. There doesn't seem to be any evidence of bruising or defensive wounds. That seems a little odd to young people. If you're experienced and strong and big, you can probably contain two young people with not a lot of difficulties.
