19-Year-Old Gunman Targeted High School Graduate in Deadly Shooting after Graduation Ceremony

An ongoing dispute between the gunman and an 18-year-old graduate culminated in a shooting that left the graduate and his father dead and five others injured.
The suspect knew the victims and had been in conflict with the graduate for over a year before opening fire outside the theater where hundreds had gathered to celebrate.
The ceremony had just ended when gunfire erupted, causing chaos and panic as families attempted to flee.
extra security precautions are being taken for the remaining ceremonies, which have been rescheduled for next week.
The shooting has been called "senseless" and prompted calls for action against the city's "gang activities" and tighter gun control laws.
