How to removed news articles that are linked to my page but aren’t related to me

For 5 years now, I’ve had an article about a mass shooting at a zombiecon attached to my page. I’m neither a zombie, an active shooter, nor been to said ZombieCon so I THOROUGHLY wish to have this removed. Apparently someone in the article shares a similar name but this could be damaging to one’s career if I were to mistaken as a former active shooter.
