Stephanie Dzikowski, 22, was found shot once in the head in her upstairs bedroom at her Port Richmond, Philadelphia, home on the evening of July 30, 2015. She and her two-year-old daughter had been living with Stephanie’s father; the child was in the house during the incident and was unharmed. Stephanie had been working as a dental technician and was raising her daughter.

A man in a hooded sweatshirt was seen fleeing the area that night, and investigators initially had no immediate suspects. The case went cold for more than a year and a half while the family held rallies and appealed for information. After a true-crime television segment aired surveillance footage and details, the homicide unit received tips that pointed to a man already incarcerated on an unrelated charge. In February 2017 police arrested 28-year-old James Jones and charged him in connection with Stephanie’s death; he was later convicted of third-degree manslaughter.

Did anyone in Port Richmond recognize the hooded man or have information about activity near Stephanie’s home that night?
