New York City police investigating the home of Philip Seymour Hoffman following his tragic death from a suspected drug overdose have found up to 70 bags of heroin, according to US reports.

The 46-year-old actor was discovered by his personal assistant and his friend, playwright David Katz, on the floor of the bathroom of his Greenwich Village apartment with a syringe sticking out of his arm.

According to American media sources, several of the bags of drugs allegedly found were stamped with the ace of hearts and ace of spades symbols, both of which are said to represent brand names of heroin that street dealers use.

Meanwhile, a spokeswoman from the New York City Medical Examiner’s office said that she was unsure when the results of Hoffman’s post-mortem examination, carried out on Monday, would be released.

“Sometimes we have to perform additional testing,” she said.

Tributes from leading film industry figures and former co-stars continued to pour in for the actor last night, as the lights along Broadway’s theatre marquees were dimmed as a mark of respect to the late star.

Yesterday, Jennifer Lawrence and the cast of the Hunger Games – in which Hoffman starred as the games master Plutarch Heavensbee – released a joint statement following his death. "Words cannot convey the devastating loss we are all feeling right now,” it read. “Philip was a wonderful person and an exceptional talent, and our hearts are breaking. Our deepest condolences go out to his family.”

据外媒消息，奥斯卡影帝菲利普·霍夫曼2日被发现死在纽约家中，手臂上留有注射器，此前有报道称他很可能死于吸毒过量。当地警方4日表示，注射器里的毒品未检测出致命的添加剂。

从霍夫曼纽约住所提取的样本并未含有合成吗啡。据悉，合成吗啡是用于添加在毒品中加强兴奋感，此前已有22个吸毒过量猝死案例疑与添加剂有关。

调查人员已经确认，霍夫曼在发现死亡的前一天，在一家超市内的自动取款机上取出了1200美元的现金。

据悉，调查人员正在通过查看监控录像来确定霍夫曼死前数小时的行踪。除了银行记录外，调查官员表示，在霍夫曼家中还发现了治疗毒瘾的药物。

药物测试部门官员4日表示，目前仍未确定霍夫曼的死因。警方表示药物测试部门的结果可以确定霍夫曼的死因，但他们怀疑是毒品吸食过量。

此前有报道称，警方在霍夫曼家进行了彻底的搜查，发现了近50包海洛因。后来警方又更正称，搜出了超过65包未开封海洛因。警方表示，还在他的家中找到了若干使用过的皮下注射器，以及一些处方药。

菲利普·霍夫曼享年46岁，他出生于纽约， 2005年因在电影《卡波特》中的精湛表演力压《断背山》中的希斯莱杰荣膺第78届奥斯卡最佳男主角奖，并凭借电影《大师》《虐童疑云》和《查理威尔逊的战争》三度荣获奥斯卡最佳男配角奖提名。
