Tonya Gunn, 44, was killed in a drive-by shooting on July 7, 2014, in the Morgan Park neighborhood of Chicago. She was attending a family Fourth of July weekend gathering in the 10900 block of South Throop Street when, standing near her car, she was shot in the torso and arm in front of relatives, including her 11-year-old daughter who was beside her. Tonya was taken to Roseland Hospital and pronounced dead shortly after arrival.

Those present described a chaotic scene as gunfire erupted; family members said everyone had been enjoying the gathering until the shooting began. Tonya worked at the University of Chicago and her death was mourned by colleagues, friends and family. Her daughter has since gone to stay with her father, underscoring the lasting impact on the family and community.
