The half brother of Jacqueline Kennedy Onassis spent Christmas in an Oregon jail for a possible probation violation.
Nate Gaoiran, program manager for the Jackson County Community Justice sex offender unit did not give details but told the Medford Mail Tribune the arrest and jailing of James Auchincloss was standard procedure.
"We're investigating a possible breach of his supervision, so that's why he's currently incarcerated," Gaoiran said.
In August, the 63-year-old Auchincloss pleaded guilty to two felony counts of encouraging child sex abuse for having computer images of naked boys. A judge ordered him to serve 30 days in jail as part of three years of supervised probation.
He was arrested Dec. 22 and is being held without bail until Jan. 21.
As a boy, Auchincloss carried the wedding train of his half sister up the aisle as she married John F. Kennedy.
