After the hearing, juror Bryant Carino, of Los Angeles, was asked who was to blame for the death.
“I'm not one to point fingers,” he said. Katherine Jackson told reporters she was OK after the verdict.
A victory could have meant hundreds of millions of dollars in damages for her and the singer's three children and provided a rebuke of AEG Live, the nation's second-largest concert promoter.
Kevin Boyle, an attorney for Katherine Jackson, said he was disappointed with the verdict.
“We will be exploring all options legally and factually and make a decision about anything at a later time.”
AEG Live is controlled by Philip Anschutz, whose affiliates own The Oklahoma Publishing Company, OPUBCO Communications Group, The Oklahoman and NewsOK.com.
