Cole Harrell, 23, was shot and killed during a fight at a house party in Northeast Houston on December 17, 2017. The confrontation began around 2:30 a.m. at a home near Waterside View and Catherine Bay in the Summerwood area when a man identified as Isaiah Kain Salas-Martinez arrived armed with a shotgun and a semi-automatic pistol. Harrell tried to disarm Salas-Martinez during a physical struggle and was struck by a shot to the chest; he was pronounced dead at the scene.

Salas-Martinez fled briefly but later returned and turned himself in; he was arrested and charged with murder. Investigators questioned several party-goers and reported no other arrests. Harrell had recently completed welding school, started his first full-time job, and left behind a 5-year-old son. His family set up a GoFundMe to help with funeral costs.

What details about that night or the people who were at the party might help explain how the confrontation escalated to deadly violence?
