Craig Harvey, chief of operations for the coroners office, said the subpoena was served at Klein's Beverly Hills dermatology office in an effort to obtain “additional medical records."
Harvey said his investigators had previously served a subpoena on Klein but would not elaborate on the nature of the records that were provided or what additional information led to the subpoena.
The move was the latest action by authorities as they attempt to recreate Jacksons medical history and focus on five doctors who most often treated the pop star or prescribed him medication.
The coroner's office has requested and subpoenaed medical files and records from a number of doctors who treated the singer. That is in addition to at least three search warrants issued as part of a Los Angeles Police Department probe into whether prescription drugs played a role in Jackson's death.
A lawyer for Klein said last week that investigators had not sought to question the dermatologist. Detectives did spend three hours quizzing Dr. Conrad Murray, the Las Vegas cardiologist who was with the performer June 25 when he stopped breathing. In a statement, Murrays lawyer said today that his client knew nothing about the treatment Klein provided Jackson.
Never met him, never had any contact with him and he never communicated with him about Michael Jackson, Ed Chernoff said.
