Two key witnesses to the late pop king Michael Jackson's death were finally interviewed by detectives from the Los Angeles Police Department (LADP), it was reported by a popular wetsite.

In an article posted by the RadarOnline. com, Alberto Alvarez, the security guard that made the 911 call, and Michael Amir, Michael Jackson's chief of staff, were interviewed Monday at the office of their attorney, Carl Douglas. The two men were interviewed separately, and the interview was audio taped.

A well-place law enforcement source was said to claim that information provided by the men was extremely "helpful" to the investigation.

Both witnesses were very "thoughtful and honest with their answers, and both of their stories were consistent." Total time the two were interviewed was about 2 1/2 hours, he added.

The post said that Alvarez and Amir were at the scene on June 25 when Michael Jackson died. Alvarez was in the room with Michael Jackson and Dr. Conrad Murray, Jackson's personal physician in the crucial moments before the ambulance arrived.

Two detectives from the LAPD Robbery Homicide Division conducted the interview, and the insider says, "Investigators were very impressed and thankful that neither men have spoken with the media, nor will they. There are no plans at this point for a follow-up interview, but if necessary, both will gladly comply."

Michael Jackson was pronounced dead on June 25 after he was rushed to Medican Center of University of California, Los Angeles. He was busy rehearsing for the London concert. The investigation into the cause of his death was ongoing. Los Angeles Coroner's office has classified his death as homicide, and the focus was put on Conrad Murray. Murray has admitted he had administered Profopol, a potant sedative on Jackson to relieve him of insomnia.

Jackson's family plans to inter his body on Thursday, in the Forest Lawn Cemetary in Glendale, north of Los Angeles.
