In the spring of 1998 Chester, Pennsylvania, became the scene of a violent death.

Decades later the case remains unresolved. No arrests have been announced, no suspects publicly identified, and few facts about his final hours or the investigation have been released. That gap in information leaves many basic questions about what happened and who was responsible.

If anyone knew Alfonza Cottman, saw something in Chester around April 18, 1998, or has information that could help, please share what is known with investigators.
