Thomas Ann Riley, 64, was found dead at her Morgan Park, Chicago home on April 5, 2022, during a police well-being check that also uncovered the bodies of her 81-year-old mother, Arteria Riley, and her 61-year-old brother, Ruben Riley. All three victims suffered fatal gunshot wounds; Thomas Ann Riley and her brother were shot in the right side of their bodies, and Arteria Riley was shot in the head. The Cook County medical examiner ruled all three deaths homicides.

Thomas Ann Riley worked as a secretary and finance manager at Saint Philip Neri School in the South Shore neighborhood and was described as punctual and devoted to caring for her partially blind mother. Her absence from work prompted colleagues to raise concerns that led to the welfare check. Neighbors called the family kind and generous, and the killings left the community in shock.

Police arrested 21-year-old Zavier Griffin and charged him with multiple felonies including first-degree murder, home invasion, and aggravated sexual assault; the motive for the killings has not been identified. Did anyone in Morgan Park or surrounding neighborhoods have recent contact with the Riley family or information about the night of April 5, 2022?
