The death of Michael Jackson was homicide due to intoxication¹ by anaesthetic, the Los Angeles coroner has formally announced.

洛杉矶验尸官郑重宣布，Michael Jackson的死亡是因为麻醉药中毒。

The 50-year-old singer died in June from cardiac arrest（心搏停止） at his LA mansion²（大厦）.

The powerful anaesthetic（麻药） Propofol and Lorazepam, a sedative³（镇静剂）, were the "primary drugs responsible for Mr Jackson's death", the report said.

Police have interviewed his doctor but he has not been named as a suspect. He has strenuously⁴（奋发地，使劲地） denied any wrongdoing.

"The cause of death was established as acute Propofol intoxication（陶醉，中毒）," the coroner's report said.

"The manner of death has been ruled: Homicide," it adds. In the US, the crime of homicide includes manslaughter.

A cocktail⁵ of drugs - including Midazolam, Diazepam, Lidocaine, Lorazepam and Ephedrine - were detected in his body, the report said.

The full toxicology（毒物学） report remains⁶ sealed, at the request of the LA Police Department (LAPD) and the city's district attorney（公诉人，检察官）.

The lawyer for Jackson's personal physician, Dr Conrad Murray, has demanded that the coroner's office release the full autopsy⁷（验尸） report, according to AP.

Edward Chernoff said he needed to know the exact levels of the various drugs in Jackson's system and said the refusal to release the report suggested "gamesmanship（搅乱战术）".

The LAPD said they were referring the case to prosecutors⁸ for possible criminal charges to be filed, according to Reuters.

An initial affidavit⁹（宣誓书） by the city's chief coroner had said that lethal¹⁰（致命的） levels of Propofol were judged to be the cause of Jackson's death.

According to those documents, Jackson's doctor told police he had been giving the singer the drug as part of his treatment for insomnia¹¹（失眠）.

But, he said he had been concerned Jackson was becoming addicted¹² to the drug and had been trying to wean him off.

The singer's remains will be buried on 3 September at the Forest Lawn Memorial Park in Glendale, a suburb of Los Angeles, in a private ceremony.

The burial was initially¹³ scheduled to take place on 29 August - on what would have been Jackson's 51st birthday.
