I know that the story of the running over of FD's mother by the nanny thing is unrelated, however LE is checking into everything about this guy's background. And this event smells also. The 24 year old nanny was also Greek and spoke no English, and had no driver's license, and FD translated for her with LE after the incident. FD happened to be in Greece when it happened. She was alive for some time. One of the grandchildren witnessed it. FD told LE his mother had "no assets, property or items of value ... no last will and testament and that this included life insurance policies, bank accounts and investments" Wow. Grifter much?
Possible he killed his own mother and made up the nanny story as a cover?
Also it's interesting that FD was accused by JD of the very same mode of violence -- running her over with a car, and I think did fake an attempt at this, swerving away from her at the last second, again in front of the children.
Man, just think, if he killed his mother and then his wife.
