According to a coroner's report obtained by E! News, the 30-year-old Parks and Recreation producer died from an accidental heroin overdose, or "acute heroin intoxication," as listed on the docs.
The report also details that "drug paraphernalia, including a spoon, syringe cap and remnants of latex balloons were recovered from the scene."
Wittels was found dead at his Los Angeles home by his assistant back in February just days before the Parks and Recreation series finale.
After news of Wittels' tragic death broke, his celebrity friends mourned his death on social media. "I am at a loss as to what to say about Harris Wittels aka Carl Sjunior, so I'll say this: He is loved and missed by so many people, including me, Bryan Pieces...and if you think you have a problem, reach out for help & support before it's too late. Your friends & family will be grateful," Parks and Rec star Adam Scott tweeted at the time.
Scott's co-star Aziz Ansari penned a lengthy Facebook post, writing, "There are so few people that you meet in life that give you that feeling that you've found a real unique, original person. Harris Wittels was one of those and we lost him yesterday. He was 30 years old. I've been devastated."
Mindy Kaling, Sarah Silverman, Seth Meyers, Rob Lowe, Ben Stiller and many more also shared their mourning via Twitter.
