Philip Seymour Hoffman's loved ones and fans aren't getting closure on his shocking death just yet, as his autopsy results are inconclusive. 

The Oscar-winning actor died on February 2 in NYC at age 46, and although police have been investigating the death as a suspected drug overdose, more tests will be needed to definitively determine the cause of death, according to People.

The medical examiners' spokesperson says it is unclear as to when the autopsy will be completed. And while no official statement has been made on what tests have yet to be done, the Associated Press is reporting that toxicology and tissue tests are usually taken in similar cases.

Philip  who won an Oscar for the 2005 film Capote and played Plutarch in last year's hit The Hunger Games: Catching Fire  was found dead in his apartment with a needle in his arm. There were upwards of 65 bags of heroin found in his home. Four people have reportedly been arrested in connection with his death.

The actor had checked himself into rehab last year after he started using heroin again, which he had used in his much younger days. Philip and longtime partner Mimi O'Donnell have three young children together. Our thoughts continue to go out to his family and loved ones.
