(Portland, OR)  --  Oregon State Police say a man who was seen falling out of a Dodge Neon onto Interstate 205 in Portland staged the incident in an attempt to extort money from his mother.  Authorities say 57-year-old John R. McPhail fell out of the car Sunday morning with his hands bound behind him and a bag over his head.  Investigators tell KOIN-TV the car McPhail fell out of was not being chased as he previously reported.  Police say that McPhail had also falsely reported he had been kidnapped from his hometown of Camas, but the story didn't hold up.
