People vanish. People are murdered.
Some cases are solved within a matter of days, weeks or months, while others go unsolved for years.
For today and the next four Fridays, the Tribune and KOIN (6) will report on cases that have eluded solution for two, 10, even 23 years, but in which someone Ñ be it families or investigators Ñ has maintained a dogged interest.
The series begins with Katie Eggleston who disappeared in Portland in the middle of a workday in August 1993.
