A custody exchange in Liberty, Pennsylvania turned deadly on a late August afternoon when 31-year-old Jesus Iran Alicia-Santiago of Buffalo, New York was shot and killed near a park-and-ride off Route 15. Alicia-Santiago was returning his two-year-old child to his estranged wife, Denissa Alvarez-Matias, when a confrontation erupted while he sat in his black Ford Explorer. Traveling with Alvarez-Matias was Leonardo Pagan-Acevedo, who allegedly retrieved a .45-caliber handgun and fired a single shot that proved fatal.

Alicia-Santiago managed to drive to a nearby Exxon station, where he was later found by responding authorities. Family members told investigators Alvarez-Matias had been upset about a new relationship he was in. The suspects fled in a red sedan.

Does anyone have information about that exchange or the red sedan seen that afternoon?
