I'd like to learn more about this incident. Do you have any useful links?
Eleven years ago, James Daniel Nelson was a 16-year-old Sacramento, Calif., runaway who called himself "Highlander," a name used in a series of fantasy films about an ancient race of humans called the Immortals, who can only be killed by their own kind. As part of a complicated conspiracy among a family of Portland street kids and homeless adults, Nelson stabbed a 15-year-old runaway to death under the west end of the Marquam Bridge. After serving more than 10 years for the teenager's murder, Nelson returned to Portland and became leader of the Thantos street family. It is suspected of killing one of its members -- Jessica Kate Williams, a developmentally disabled Gladstone woman whose brutalized body was found under the east end of the Steel Bridge on May 23.
