Felix Rios, 21, was shot and killed on July 25, 2021, in Arlington, Texas after agreeing to meet Cristian Gonzalez, 17, at an Arlington park for a fight. The meeting followed a verbal altercation earlier that day at a house party in Grand Prairie between Rios and Gonzalez’s brother. When Rios arrived at the park, Gonzalez allegedly shot him twice.

Rios’s family told investigators Gonzalez planned to flee to Mexico; officers arrested Gonzalez at his home based on that information. Gonzalez was charged with murder.

The case shows how a daytime argument escalated to deadly violence and raises questions about the events leading up to the park meeting and the missing firearm. Anyone with information about the altercation, the park meeting, or the weapon is asked to come forward.
