Prosecutors believe an Olathe, Kansas serial murder suspect is now responsible for the deaths of as many as nine people. They held a news conference yesterday and tied John Robinson Sr. to at least five missing person cases dating back to the 1980’s, one of whom may be among the five women found dead in barrels discovered in Linn County, Kansas and Cass County, Missouri. Authorities say the other four victims found in the barrels remain unidentified. Johnson County, Kansas Prosecutor Paul Morrison says most of the victims came to the Kansas City-area after Robinson offered them jobs or financial support.
