Randy Jackson, brother of the late pop legend Michael Jackson, was hospitalized Tuesday in Southern California.
Jackson, 48, experienced chest pains around noon on Tuesday and was taken to Huntington Memorial Hospital in Pasadena, where he is currently awaiting the outcome of tests, a source close to the Jackson family who spoke only on the condition of anonymity because he was not authorized to speak publicly said.
The source told The Associated Press that doctors at the hospital think it was a mild heart attack, but this has not yet been confirmed.
On Monday, Randy Jackson was in court with his family for a hearing in the involuntary manslaughter case of Dr. Conrad Murray who is accused in connection with Michael Jackson's death. Randy Jackson arrived after everyone else and stopped to hug his parents, his brothers and sister LaToya before the hearing began.
Last week, he made an appearance on CNN's "Newsroom" and expressed the opinion that Murray should be charged with first-degree murder. He also said he thought others were implicated in Michael's death.
In a series of posts on Twitter in the last few weeks, Randy Jackson said he had succeeded in stopping an unapproved tribute show to Michael in Rome which had been scheduled on June 25, the anniversary of his death. He said he also had been talking to officials at Forest Lawn Glendale in an effort to have fans admitted to the area near Jackson's tomb on the anniversary.
He said in his posts that the fans had been a great source of comfort to him.
"At times, I'm sad & broken," he tweeted. "But ur supprt helps 2 encourage me and fuel my motivation 2 continue this fight 4 truth&justice."
