The last i heard was the family refused to release the details when asked and just wanted the contact to stop and their privacy maintained. It was known they were inappropriate, "overly friendly", which should have resulted in further investigation of Foley's dealings with pages to see if it was an isolated incident.
The family's privacy would not be at risk.
'Overly friendly" is a strictly subjective term and is open to wide interpretation. They Parents said specifically the emails were NOT of a sexual nature.
