SANTA MARIA, Calif. – The boy who says Michael Jackson molested him acknowledged under cross-examination yesterday that he told an administrator at his school the pop star “didn’t do anything to me.”

The teenager was asked about conversations he had with Jeffrey Alpert, the dean at John Burroughs Middle School in Los Angeles, where the boy had a history of acting up in class.

“I told Dean Alpert he didn’t do anything to me,” the boy said under questioning by Jackson attorney Thomas Mesereau Jr. “I told him twice.”

Prosecutors allege Mr. Jackson, 46, plied the boy, a cancer survivor, with alcohol and molested him at his Neverland Ranch in 2003.

Mr. Mesereau, during his cross-examination of the boy, quoted Mr. Alpert as telling the youngster: “Look at me, look at me…. I can’t help you unless you tell me the truth – did any of this happen?”

When asked when the conversation occurred, the boy said: “I believe it was after I came back from Neverland.”

It was not clear in court why the dean asked the boy about Mr. Jackson. However, when a television documentary on Mr. Jackson aired in 2003, the boy was shown in it.

Mr. Mesereau confronted the teenager with school records that showed nine teachers had complained about the boy’s disruptive behavior, events the boy acknowledged.

Of one teacher, he said, “I felt as if he didn’t deserve respect as a teacher. I didn’t respect him as a person.”

He complained on the witness stand about the teaching methods of virtually every teacher mentioned. “When I would stand up to teachers, the other students would congratulate me,” he said. He added: “I was argumentative at times. I didn’t like the way they taught me. I wasn’t learning anything.”

Later in the day, Los Angeles attorney Thomas Flicker Forsyth said in an interview he was representing a potential witness who “was part of the school administration at the time he had contact with the victim.”

He said his client met with prosecution and defense attorneys Saturday, and that he believed his client would be called as a witness.

Mr. Mesereau attempted to attack the heart of the conspiracy case by showing the so-called “rebuttal video,” stopping it at points where the boy speaks and asking if he was telling the truth. In most instances the boy said he was.

The boy said he, his mother, and brother did not discuss any plan to lie in the video, although he said at times his mother said things suggested to her by Jackson associate Dieter Wiesner.

Prosecutors allege that Mr. Jackson’s associates had the boy’s family make the video after the broadcast of the documentary, in which Mr. Jackson said he allowed the boy to sleep in his bed while he slept on the floor. The prosecution claims the rebuttal video was staged and scripted.

Mr. Mesereau also elicited testimony to amplify defense contentions the boy developed a grudge against Mr. Jackson and was troublesome at Neverland.

The boy acknowledged he felt Mr. Jackson abandoned him after his cancer went into remission. He said an SUV given to the family was taken back by Mr. Jackson’s staff for repairs and was never returned. Similarly, he said a computer was taken back for repairs and never returned.
