CHICAGO — Three family members were found dead Tuesday from gunshot wounds inside a Morgan Park home.

At around 4:30 p.m., police responded to the 11300 block of South Green Street. When authorities entered the residence, two women and a man were found dead.

Police said an 81-year-old woman, later determined to be Arteria Riley, had a gunshot wound to the right side of her head, a 64-year-old woman, identified as Thomas Ann Riley, was found with a gunshot wound to the torso and a 61-year-old man, later determined as Ruben Riley, was found with a gunshot wound to the torso.

Crisis responder Andrew Holmes told WGN News the victims are a mother and her two children. They have reportedly lived in the neighborhood for decades. Family members told him they believe the shooting happened sometime in the last 24 hours.

“It’s horrible and to have known him for such a long time,” a neighbor named Greg said. “When something happens like this, when it’s so close to you, it affects you a lot differently.”

Police are investigating the incident as a homicide. They are currently investigating to determine if the shooting was domestic-related or a possible home invasion.
