A portrait of a highly isolated young man is emerging as a state office investigating the Newtown school shooter seeks the release of his educational records.
Connecticut's child advocate office is seeking Adam Lanza's records as part of an investigation with its Child Fatality Review Panel into last year's massacre of 26 people at Sandy Hook Elementary School.
The 20-year-old Lanza committed suicide after the shootings.
The panel reviews unexpected child fatalities. It has obtained some of Lanza's school and hospital records, but the attorney general asked on the panel's behalf for the release of his educational records.
Faith Vos Winkel, assistant child advocate, said a theme is emerging of a very isolated child. She said the case is like a puzzle for which they have only a few pieces.
