According to The Sun, Gene died of cancer back in 2012 when he was 77 years old. The type of cancer wasn't specified.

But it still feels as if he's a part of his family's reality show. They speak highly of him all the time.

The family continues to post pictures of Gene on social media and talk about his accomplishments. He served in the army and fought in the Korean War and earned a bronze star, according to Find a Grave. In one Instagram post, Todd says that his dad was just 16 years old when he saw combat.
