The death of Michael Jackson was on the minds Sunday of church-goers in Mount Vernon who wonder if prescription drugs may have been the cause.

"Anyone, any pharmacy dispensing that much drugs to one person, it's a shame," says Betty Edwards, who was attending services at Grace Baptist Church.

On Saturday, the cardiologist who was with Jackson during his final moments, Dr. Conrad Murray, sat down with investigators for three hours. His spokeswoman said he is not a suspect in Jackson's death.
