验尸官办公室最新调查结果显示，迈克尔杰克逊系他杀，死亡疑云依旧笼罩着这位昔日King of the Pop。

Hints:
Michael Jackson
propofol
lorazepam
benzodiazepine
Further investigation by the coroner's office through statements through interviews, through the autopsy, through the toxicology findings, led to the conclusion that the levels of propofol found in Mr. Jackson's body were at levels similar to general anaesthesia when someone is put under for a surgical procedure. The coroner also found that the levels of lorazepam were pharmacologically significant and that they played a contributing role in the death of Mr. Jackson because his benzodiazepines work in conjunction with the propofol that heightened the effects that each drug has. Following these findings, the coroner's office concluded this was in fact, a homicide, that Michael Jackson's death was a homicide. And more specifically, the coroner's office concluded that the cause of death was acute propofol intoxication coupled with a contributory factor of the additional benzodiazepines in his system. Upon discovering and ruling and determining this to be a homicide, the investigation continues. And the investigation centered on the dates proceeding his death, the investigation centered on the events of January, excuse me, June 24th and June 25th 2009 and the question became what occurred between June 24th 2009 when Michael Jackson shown in this pictures performing at Staples Center singing Earth Song, what happened between that time and approximately 12 hours later when Michael Jackson is dead on June 25th 2009?
验尸官办公室所进行的进一步调查、问讯、声明、尸检、毒理检查之后，得出的结论认为，杰克逊体内的异丙酚含量与动一项大手术所进行全麻术所动用的异丙酚量相当。验尸官办公室还发现，杰克逊体内还有大量克拉西泮，它可能对杰克逊之死产生了关键作用，因为苯二氮与异丙酚相互作用，会增强他所使用的每种药物的效果。验尸官办公室随后得出结论，杰克逊之死系他杀。验尸官办公室还进一步得出结论，杰克逊是死于急性异丙酚中毒，引发他死亡的一个因素是他体内超量的克拉西泮。 在引导、调查并确认这是一起他杀案件之后，调查工作在继续进行中。调查将以他的死亡时间2009年6月24日和25日为重点展开，焦点问题就是，从6月24日迈克尔杰克逊在Staples广场演出《Earth Song》到25日被发现死亡，这12小时内到底发生了什么。
