Chief Keef‘s 19-year-old stepbrother Ulysses “Chris” Gissendanner III has been found dead. The up-and-coming rapper is another victim of Chicago, Illinois’ shooting epidemic.

According to DNA Info, Gissendanner was shot in the back of the head on the Far South Side on January 2nd  in a car near 124th Street and South Avenue while visiting his uncle in West Pullman. He later died at Roseland Hospital. Alfonso Cozart (Chief Keef‘s biological father) was stepfather to Gissendanner also known as YPN Boomtown. Keef was related to Gissendanner through marriage.

Alfonso Cozart who no longer speaks to Chief Keef, said that the murder makes him worry about his son’s well being.

“As a caring father, who wouldn’t worry about that? I do want my son to have success and have a long, positive life, and I hope the best for him.”

Cozart also added that he doesn’t want Keef’s fame to overshadow Gissendanner’s death:

“He just graduated high school, and was in college and had a job. He was a positive person,I’m not trying to get publicity of Chief Keef being my son. I want you to focus on Ulysses. He’s the one that’s gone.”

Chief Keef seems unmoved by the tragedy, as he continues to tweet without even mentioning the passing of his family member.
