In the early morning hours of January 23, 2017, 44-year-old Carmelle Erbie Cajuste was shot and killed at about 6 a.m. near the front door of a residence on the 1300 block of Truman Street in Hammond, Indiana. She suffered a fatal gunshot wound to the head and was pronounced dead at the scene. Two other people, a 36-year-old woman and a 27-year-old man, were critically injured in the same shooting.

Investigators identified Joseph E. Barner as the person who had gone to Cajuste’s home and opened fire. A manhunt followed; Barner was located and arrested that evening in Lynwood, Illinois. He was charged with one count of murder and two counts of attempted murder and later pleaded guilty but mentally ill in connection with the shooting.

Does anyone have information about Carmelle Cajuste, the neighborhood on Truman Street, or the events of that morning that could shed light on what led up to the attack?
