A Denver Sunday afternoon Broncos watch party ended in a fatal shooting that killed 67-year-old Jose Diaz-Luevano. The shooting happened at a home near 36th and Lafayette while Diaz-Luevano was hosting family and friends and reportedly grilling food for a 33-year-old man identified as Clay Baeza-Garcia.

Witnesses say an argument broke out between Baeza-Garcia and Diaz-Luevano’s 36-year-old son, Alejandro Diaz. During a struggle over a firearm Baeza-Garcia allegedly produced, the gun discharged and a single shot struck Jose Diaz-Luevano in the chest. A child at the party reportedly ran from the house screaming that Papi had been shot. Attendees detained Baeza-Garcia until police arrived; he was taken into custody and later held on suspicion of first-degree murder.

What additional details about the hours before the shooting or the relationships among those involved can anyone add?
