According to a police statement from Riley, Grigorieva's bodyguard Kristian Otto Herzog promised both him and Kowal money that Grigorieva won from the dispute, condos, Hollywood connections and maybe even eternal life if they would say what Herzog told them to on the witness stand. When that didn't work, Herzog, who served 255 days in jail in 2009 after pleading guilty to impersonating an officer, allegedly turned to the persuasive strategy proven successful by Don Corleone, Tony Montana and others of their ilk: He made reference to the shotguns in his car, threatened to have dirty cops "take Riley out" and, according to Riley, tried to run him over on his own street.
It remains to be seen how this will affect the case itself, and as of now, Grigorieva's camp is denying all allegations. In the meantime, I need a shower.
