The meeting, held under extraordinary secrecy, also included testimony from Jamie Masada, the comedy club owner who first arranged for Jackson and the boy to meet, according to the source, who spoke on condition of anonymity.
Masada declined to comment Tuesday night. He has said previously he promised to introduce the boy to Jackson when the boy was undergoing chemotherapy in 2001.
A court order bars the media from contacting any minor called to testify before the grand jury.
Tuesday was the second day of grand jury hearings. On Monday, the grand jury heard testimony from the psychologist who first reported to authorities the boy’s claim that he was molested by Jackson, two other sources close to the case said Tuesday.
Psychologist Stan J. Katz testified Monday before the grand jury, according to the sources. Also testifying Monday was attorney Larry Feldman, who was first contacted by the boy’s mother, according to one of the sources.
Feldman, who represented a boy who accused Jackson of molestation in 1993, took the current accuser to Katz last year. The boy told Katz of the alleged molestation and the psychologist then went to authorities.
