I recall a segment about 2 young ladies that were foreigners. sorry but my memory is fuzzy on this. What I remember from the story is that they were hitchiking around the US, one girl was from Sweden and the other was Russian I think, and the girls' belongings were found in a dumpster, including backpacks, clothing, purses, & wallet with Identification. Im not sure what became of them, I think they were murdered. Does anyone remember this case and if it was ever solved. It creeped me out from what I remember of it!

Yes, I was watching this one for the first time earlier tonight coincidentally. They were Swedish girls found raped and murdered (by stabbing) and dumped in the woods in Santa Barbara County about a month after they were last seen. All of their belongings were found a few days after they were last seen in City of Commerce at a convenience store dumpster. There was a caller 8 or 9 years later in 1991 that called into the Swedish consulate in San Diego and told the lady there that he knew the guy that killed them. He provided them with the supposed killer's name Lorne, a full physical and description, and a description of his car (white van w/ green canoe on top).

This one has some very sinister sounding music when they show the map of California superimposed over the girls when they're trying to hitch a ride (about 1:47:14 of the way in on Vol 5 Title 2).

At the end of the segment, Robert Stack said that they found the caller and they found Lorne. I wonder what became of that lead. Does anyone know if this one was solved yet?

Their names were Marie Lilienburg and Maria Wahlen. Apparently Loren was never charged in the crime because they're murder is still listed as unsolved:

Wow, that's all you could find on this case? It doesn't even list stabbing as cause of death and says unknown instead.

That Kym Morgan case sounds sort of interesting. http://www.newspress.com/coldcases/kymkiller.htm

yeah , think it was californa ..

Yes, definitely California.

In my opinion, Loren Herzog and Wesley Shermantine are the men that murdered the Swedish hitchhikers Marie Lilienberg and Marie Wahlen in 1983. The “Speed Freak Killers” lived outside of Stockton – a direct line to Interstate 5 – and a likely place for hitchhikers to pick up a ride to LA or SF. The decomposing bodies of Lilienberg and Wahlen were found decapitated and discarded on SR166. Herzog and Shermantine, teenagers, most likely mapped the route from 1-5 to SR166 to US101 to City of Commerce where the Swedish women’s belongings were found in a dumpster. Then, after having dispensed with the bodies and belongings, returned to Linden CA on I-5. Another probability is a truck with a camper-shell can give the impression of a van, and addicts often look like they have protruding watery eyes. As the Speed Freak Killers aged (Herzog married with children) they may have become complacent. With the advancements in Forensic Science and Crime Scene Technology from 1983 to 1998, I believe these serial killers were finally convicted and incarcerated for the homicides of young Caucasian females.

Update February 2012:
From San Quentin death row Wesley Shermantine gave clues and a map that lead to a search for long-lost murder victims. San Joaquin Sheriff's Office heading up the search for human remains dredged from an old well in Linden, CA and unearthed 1,000 bone fragments in a mass grave Shermantine calls "Herzog's Boneyard". Herzog committed suicide in January 2012 after learning his partner in crime was planning to reveal the locations of these serial killers victims. The killings spanned two decades-80's and 90's-and two states, California and Utah. I believe Marie Wahlen and Marie Lilienberg fell victim to the "Speed Freak Killers" in the 1980's. Likely the young women hitch-hikers were a few of the first on a long drug induced killing spree. Because the bodies were found, the killers began dumping the other victims in wells on rural properties where they were less likely to be found by hunters.
