Glenn Hector Montellano, 21, was shot in the head and died after a large brawl on the West Side of San Antonio on July 26, 2017. The shooting happened near SW 21st Street and El Paso Street during a heated argument that escalated into a physical altercation involving nearly 30 people. Montellano was taken to University Hospital and later succumbed to his injuries.

San Antonio police arrested two people, Christian Lozano, 20, and Julias Barron, 18, on charges of aggravated assault with a deadly weapon; police said those charges might be upgraded as the probe continued. Authorities described the shooting as arising from a feud between two families and said investigators were working to determine everyone’s role and whether there were additional suspects.

Are there witnesses who were at SW 21st Street and El Paso Street that evening who can provide details about how the fight began or who fired the shots?
