A Christmas night visit to a Newark rowhouse ended in multiple deaths and changed three families forever. Fifteen-year-old Kasson Mormon was at a Schley Street home on December 25, 2013, visiting a friend when gunfire erupted around 10 p.m. Kasson, a freshman at Central High School who sang in the choir, was fatally shot outside the three-family residence.

Also killed that night was 13-year-old Zainee Hailey, who had been taking out the trash, and 14-year-old Abdul Frazier, who was critically wounded outside his first-floor residence and later died from his injuries. The shootings pushed the city’s homicide count to 100 for the year. Investigators arrested a 15-year-old suspect, who was charged in the killings; authorities said the motive may have involved the suspect feeling disrespected after a victim reportedly hit on his girlfriend. The suspect later pleaded guilty under a plea agreement.

Does anyone have information about Kasson’s last night or the Schley Street neighborhood that could help explain what happened?
