Heroin? Items Found Near Comic Harris Wittels' Body Suggest Hard Drug Use — Plus Inside The Funeral

Drug paraphernalia found near Harris Wittels' body suggest the comic was using heroin "or something like it" before his unexplained death last week, a source close to the investigation tells RadarOnline.com exclusively.

The Los Angeles County coroner has deferred a ruling on what killed the 30-year-old Parks & Recreation producer until toxicology results are back from the lab in about six weeks. But investigators have strong clues it was an accidental drug overdose.

Authorities at the scene recovered "a spoon, a syringe cap and balloons" which indicate use of heroin "or something like it," the source tells Radar.

Wittels was found dead in his home in the Los Feliz section of Los Angeles by police responding to a reported "accidental death" on February 19.

Today, his family is holding a funeral for Wittels in his hometown of Houston, Texas, where he will be buried. A scholarship fund has been established in Wittels' name at Houston's High School for the Performing and Visual Arts, where he graduated in 2002.

Wittels was a co-exective producer of the NBC sitcom and also worked as a stand up comic. His producer credits include TV's Eastbound & Down and Secret Girlfriend. Along with producing, Wittels is also credited with acting in Parks and Recreation episodes as Harris, a clueless worker at Pawnee's Animal Control department.
