Witness Alleges Jackson Abuse

The 14-year old brother of Michael Jackson's accuser described the molestation allegations against the singer for the first time, saying he saw Jackson touching his brother as the boy slept on the singer's bed.

He said that he twice saw Jackson masturbating with one hand while the other was in his brother's underwear. He did not state the dates of the incidents, which the prosecution says followed a February 2003 TV documentary in which Jackson appeared with the boy at his Neverland ranch.

The brother wound up his testimony for the prosecution Tuesday by saying Jackson told the boys never to say what happened at the ranch, "even if they put a gun to your head."

He now faces cross-examination by Jackson's lawyers.

"This is really the heart of the case," says CBS News Legal Consultant J. Randy Taraborrelli. "There are four acts of molestation alleged in the indictment and these are two of them."

"You could have heard a pin drop in that courtroom yesterday as this young man was telling his story," Taraborrelli added.

"I didn't know what to do," the witness said, adding that he watched both incidents for a few seconds before going to a guest room. Speaking calmly, directly and unemotionally, the boy said the alleged molestations occurred two days apart.

Jackson stared at the boy as he testified, CBS News Correspondent Vince Gonzales reports.

The defense says the allegations are a fiction created by the children's mother in an attempt to extort money from the pop star. The accuser's brother faced more questioning Tuesday.

"I think the real test will be cross-examination," said former San Francisco prosecutor Jim Hammer.

Jackson's chief attorney Thomas Mesereau's cross-examination is likely to be very intense, suggesting that the 14-year-old witness has changed his story, and implying that the accusers entire family made up the allegations, reports CBS News Correspondent Steve Futterman.

The boy said the molestations occurred sometime after Jackson had shown him and his brother sexually explicit magazines kept in a suitcase in his bedroom. "We all looked at them one at a time," he said.

The defense has said Jackson had "girlie" magazines in his house but never showed them to children.

District Attorney Tom Sneddon projected on a courtroom screen the covers of magazines, including one called Barely Legal that depicted a young woman with her breasts exposed.

Jackson, 46, is accused of molesting a 13-year-old cancer survivor at Neverland, giving him alcohol and conspiring to hold the family captive to get them to rebut a damaging documentary in which Jackson said he allowed children to sleep in his bedroom.

The accuser's brother also described an incident in which Jackson grabbed a mannequin that he kept in his bedroom and "he pretended like he was having intercourse with it" on a bed while fully clothed and laughing.

Jurors were shown a photo of a mannequin depicting a girl with braids.

The brother said Jackson had once asked him if he ever masturbated. The boy said he answered no. "Then he said to me, 'Everyone does it. You should try it. It's OK,'" the witness said of Jackson.

He also told of Jackson conducting drinking parties with his young boy guests in which he served them wine and called it "Jesus juice."

The witness said that on the night he discovered Jackson with his brother, he pushed open the door to Jackson's room and, "I saw directly onto the bed. I saw my brother was outside the covers. I saw Michael's left hand in my brother's underwears and I saw his right hand in his underwears," he said.

He described his brother as curled up and snoring slightly, and he said he saw Jackson masturbating. "He had his eyes closed," the witness said.

Two days later, he said, he encountered a similar scene.

"I went upstairs. The same thing was happening but my brother was on his back. ... My brother was asleep. Michael was masturbating while he had his left hand in my brother's underwears."

The members of the accuser's family have been put on the stand a lot sooner than most observers had expected. The accuser himself may testify shortly.

"I think they probably made this decision on the strength of the defense's opening statement," says CBS News Legal Analyst Trent Copeland. "This is a bet-the-farm strategy."

The courtroom was still during the testimony. Sometimes the boy spoke softly and had to be told to speak up, but he did not hesitate to answer questions.

Jackson's mother, Katherine, and father, Joe, were present but showed no reaction. Jackson occasionally leaned over, put his hand on his lawyer's shoulder and whispered in his ear.

Jurors listened intently and a few took notes.

With all the graphic testimony, Jackson seemed concerned, and less willing to talk, as he left court, reports Gonzales.

"I'm sorry, I'm under a gag order," Jackson said.

The witness also testified that Jackson showed him and his brother Internet sex sites, slept in bed with them and appeared before them naked and sexually aroused at Neverland.

"Me and my brother were watching a movie and Michael walked up naked," the witness testified. "Me and my brother were grossed out. He sat on the bed and said it was natural," then left the room.

Sneddon asked if anything was notable about Jackson's appearance, and the boy, using a slang term, said Jackson was aroused.

When Sneddon asked him about his choice of words, the boy said, "That's what Dr. Katz called it."

The brother also described Jackson as making crude sexual jokes in their presence.

The rosy-cheeked boy appeared to grow fatigued by the end of the day, yawning widely and rubbing his eyes with his hands.
