On the evening of January 23, 1999, 26-year-old East Hartford Police Officer Brian Aselton responded to what was dispatched as a routine noise complaint at an apartment building. Inside, a violent home invasion was underway; the tenant had been bound, gagged, and severely beaten. Aselton’s arrival interrupted the robbery and he entered the building alone after his backup had cleared the scene.

Aselton encountered a man covered in blood who was leaving an apartment. A struggle followed and the man produced a handgun that had been taken during the invasion, firing a single shot that struck Aselton in the forehead. The officer died a short time later at a local hospital. A suspect identified as Alex Sostre was later arrested in connection with the shooting, and three others — Nency Forty, Erika Villegas, and Jose Gonzalez — were apprehended for roles in the home invasion.

What details about the incident or the people involved might help explain how this robbery turned so deadly?
