chief keef*Is there a war afoot in Chicago?

It was reported that rapper Chief Keef’s step brother was shot in the back of the head and killed in Chicago last week.

NBC Chicago says, Ulysses Gissendanner III, 19, was gunned down last Wednesday near 124th Street and South Union Avenue, DNAinfo reports. Gissendanner reportedly had been visiting his uncle in the West Pullman neighborhood when he was shot in a car.

This event comes shortly after controversy arose regarding the rapper’s alleged involvement in the shooting death of 18-year-old rival, Joseph ‘Lil JoJo’ Coleman.

The family, however, is not sure if the murders are linked.
