Santa Maria, Calif. ? The mother of the boy accusing Michael Jackson of child molestation testified Thursday that the star’s aides threatened her family unless she portrayed the singer in a positive light on the video made to defuse the growing threat of bad publicity.

She said she was given a script for the video, made Feb. 20, 2003, but when she deviated from what she had been told to say, Jackson aides took her to get travel documents so she could be sent to Brazil. The woman testified that an aide threatened to kill her parents and a boyfriend if she refused to leave the country.

After nearly four hours on the stand Wednesday, the woman returned for more than three hours of direct testimony Thursday that continued into the afternoon. In addition to being the mother of the accuser, the woman is the key witness on the conspiracy accusations.

Jackson, 46, is charged with 10 counts, including child molestation, attempted child molestation, administering alcohol to a child to aid in the commission of a felony and conspiracy to kidnap, extort and falsely imprison the accuser’s family. The accuser was 13 in the period from Feb. 4 to March 12, 2003, when the prosecution says the crimes occurred.

There are 28 overt acts associated with the conspiracy charge, including buying plane tickets for the family to go to Brazil, monitoring phone conversations and closing down the accuser’s family’s apartment without permission.

Deputy Dist. Atty. Ron Zonen has been walking the woman through the major acts. Defense attorney Thomas Mesereau Jr., who has been restrained during the direct testimony, will get his chance during cross-examination.

Much of Thursday’s testimony centered on Feb. 20, 2003, the day the family finished the rebuttal video. Later that day, the mother was interviewed by the Los Angeles County Department of Children and Family Services, which was investigating whether she or Jackson had mistreated the children. No charges were filed.

The rebuttal video was one tactic used by the Jackson camp to offset the potential backlash from a 2003 British documentary. On that tape, Jackson held hands with his accuser while saying he often slept in the same bed with children, but in a nonsexual way.
