Joe Jackson: Stress Didn't Kill My Son

Nearly two days after the untimely death of Michael Jackson, the King of Pop's father told FOX News in an exclusive interview that he does not think stress killed his son.

In an interview with FOX News' Geraldo Rivera, Jackson's father Joe said "we're going to miss the great superstar, the biggest known in the world."

When asked if he will be more well known in death than life, Joe Jackson said the attention "should have been done while he was alive so he could enjoy it."

Joe Jackson also said Michael's children are doing "fantastic," are with his family and "are enjoying themselves with the other kids."

A statement released to People magazine by Jackson's family Saturday said their "pain cannot be described in words."

The family said they "miss Michael endlessly" and in "one of the darkest moments of our lives we find it hard to find the words appropriate to this sudden tragedy we all had to encounter."

"Our beloved son, brother and father of three children has gone so unexpectedly, in such a tragic way and much too soon. It leaves us, his family, speechless and devastated to a point, where communication with the outside world seems almost impossible at times."

A person close to the family told the Associated Press that while there were reports that the singer was distant from his family, Jackson spoke with his mother Katherine quite regularly and his father, Joe, had seen his son shortly before his death. His other eight siblings, including fellow superstar Janet, may not have talked to him recently but were not estranged.

Much of the family was holed up Friday inside the Jackson family's Encino compound, including his three children, according to the person, who described them as doing looking "pretty good."

"I don't think it's fully set in yet," the person said.

No family members were present in the mansion when Jackson died Thursday, the person close to the family said. In the 911 call released by fire officials Friday, an unidentified caller tells a dispatcher that Jackson's doctor is performing CPR.

Asked by the dispatcher whether anyone saw what happened, the caller answers: "No, just the doctor, sir. The doctor has been the only one there."

Jackson appeared to have suffered a heart attack, another person with knowledge of the situation who was not authorized to speak publicly and requested anonymity told the AP on Friday. A heart attack is a blocking of the arteries that deprives the heart of adequate blood and can cause cardiac arrest.
