On the evening of December 18, 2024, Margaret Mary Sangerman, 73, was killed inside her home on North Warren Street in the Miller Beach neighborhood of Gary, Indiana. Police responding to a report of a shooting found her inside the house with multiple gunshot wounds; she later died at the hospital. Her 69-year-old husband, Mike, was found in the front yard with a gunshot wound and was taken to the hospital.

Investigators say the couple’s blue Nissan Xterra, with personalized plates reading BLUE MOM, was stolen from the residence during the attack and later recovered abandoned in a Chicago suburb with the help of license plate reader technology. A suspect has been described as a male wearing a brown trench coat and a ski mask. No arrests or motive have been announced and the investigation remains active.

Friends and family recall Margaret, known as Pegg, as energetic, fun-loving and devoted to her family. If anyone in Miller Beach or the surrounding area has information about that night, please come forward to assist the investigation.
