Michael Jackson's sister La Toya is convinced she knows the group who killed her superstar sibling - and has vowed to go public with the murderers' names if the truth doesn't come out in court.

The King of Pop's sibling alleges a number of people took advantage of the singer and killed him to gain control of his music publishing catalog, which she claims is worth more than $1 billion.

Jackson has already informed the authorities of who she believes is responsible - and she has promised to reveal the culprits to the world. She says, "If justice is not served in the courts, I will name them myself. I have made it clear to the police who is responsible. They must ensure, for Michael's sake, that the outcome is right."

The head of Los Angeles police, William Bratton, sparked speculation last week (begs06Jul09) that Jackson's death was the result of foul play after confirming that cops are refusing to rule out the possibility the Thriller legend was murdered. (PAW/WNT/KD)
