A Halloween party on the northeast side of Indianapolis ended in a mass shooting that killed 16-year-old Kalin Washington and wounded nine others. The gathering, held after midnight on October 29, 2023, in a building in the 5100 block of East 65th Street, had been promoted on Snapchat and drew hundreds of young people. When Indianapolis Metropolitan Police arrived they found a large crowd fleeing and multiple people with gunshot wounds; Kalin was pronounced dead at the scene.

Police later arrested 19-year-old Jalen Helm on charges related to organizing and promoting illegal parties, including the October 29 event. Authorities accused Helm of supplying alcohol and narcotics at those gatherings and knowingly allowing armed individuals to attend; he faced multiple charges including reckless homicide. Investigators stated the probe into who fired the shots that night remained ongoing.

If anyone attended that party or has information about who fired the shots, please share what you know.
