Christopher King, 49, was shot and killed after an argument on the night of May 29, 2017, in Boulder, Colorado. What began as a social gathering on the Pearl Street Mall — a party the host had accidentally invited King to but allowed him to attend — moved to the Bramble and Hare restaurant. Tension between King and 32-year-old Louis Sebastian reportedly escalated over political disagreements and a mutual romantic interest, and flared further when the group’s dinner came up short by about $100.

King and Sebastian stepped outside to argue, and shortly afterward gunfire rang out. A restaurant chef, a former Marine, saw Sebastian return inside and continue shooting King, then tackled and disarmed him while the manager helped restrain Sebastian. King was taken to a hospital and later died; investigators recovered eight shell casings at the scene. Was anyone at the party able to shed light on how the confrontation started or on the events leading up to the shooting?
