Young couple goes on van tour of US, boy comes back with van - no girl

honestly, i think this is the only interesting part of the story - now that the mystery is done, girls falling in love with psychos or baby men unable to control their rage is the dominant queries - but i think the 'what do you do when your son tells you he killed someone?' is WAY more interesting and the only thing i'd pay much attention to the reporting on ( i can catch any of umpteen shows on netflix if i wanted to scratch the other itches)
The big question is, did they "find themselves"? Seems like they found out that they were the same people who initially left in that van, and their own personality flaws got each of them killed in dramatic fashion. A young, naive woman who is dependent on a manipulating, dirtbag boyfriend who is capable of killing someone. It's heartbreaking, but I do think that there is lots that can be learned from this case...especially for young women. He is who you think he is...and people don't change. The little change that does happen occurs over decades, and to small degrees.
