What Happened to Heath Freeman?

The release of Heath Freeman's cause of death came nearly four months after his manager, Joe S. Montifiore, confirmed his passing.

"We are truly devastated at the loss of our beloved Heath Freeman. A brilliant human being with an intense and soulful spirit, he leaves us with an indelible imprint in our hearts," Montifiore said at the time.

He landed on his first role on the hit NBC series, "ER." During that experience in 2001, he initially guest-starred as Kevin in an episode. He then appeared as Benjamin Frank in "NCIS."

Freeman found his luck when he was selected to portray the role of killer Howard Epps on Fox's "Bones from 2005 to 2009. During that stint, he also started working in "Raising the Bar" as Gavin Dillon from 2007 to 2009.

Even before his death, he remained one of the most in-demand stars as he was still able to start working on three upcoming films: "Terror on the Prairie," "Devil's Fruit," and "The Outlaw Johnny Black." All of which already reached their post-production.
