Tevin Kirkman was 22 when he was shot and killed at his Humboldt Park home in Chicago on May 24, 2013. He suffered three gunshot wounds to the head and two to the body, was taken to Mount Sinai Hospital, and was pronounced dead shortly after arrival. The Cook County medical examiner ruled cause of death as multiple gunshot wounds.

Investigators reported the killing was likely tied to a turf war over drug territory between the Kirkman family and another family. Tevin’s brother Tyrone Bay-Bay Kirkman, 27, publicly vowed revenge at Tevin’s funeral and displayed a .357 revolver. Tyrone was later charged with conspiracy to commit murder; on June 11, 2013 an undercover officer recorded him taking possession of a gun intended for the revenge plot and he was arrested and held on $900,000 bail. Pierre Mayweather, 27, was also charged in connection with Tevin’s murder and was ordered held without bail.

Are there details about Tevin’s life or the neighborhood that could help clarify who was responsible?
