Key witnesses – including the 'Thriller’ star’s chief of staff Michael Amir and his security officer Alberto Alvarez - have not yet been interviewed because Los Angeles police are so busy.
Carl Douglas, a lawyer for both staff members, said: "We arranged two occasions for investigators to meet my clients.
"The first meeting was rescheduled. The second, I had to call them to inquire about the detectives' absence."Just three detectives are investigating the death of Michael Jackson.
