Late on a October night in Nashville, Tennessee, 37-year-old Luis Gonzalez-Barajas was shot dead after a brief, heated argument outside a home on Vultee Boulevard. The shooting, just after 11:30 p.m., also killed 29-year-old Franklin Bautista-Ayala. Both men had just arrived in a white Acura sedan when they reportedly argued with a man sitting on the front porch.

Witnesses and responding officers say the man on the porch, identified only by the first name Jose, allegedly produced two pistols and opened fire. A person believed to be the suspect fled in a pickup truck but abandoned it and ran back toward the house; police surrounded the home and conducted a roughly four-hour standoff. A man and a woman who exited confirmed that Jose lived there. Two pistols later were recovered outside the home and are suspected to be the weapons used.

Homicide detectives are working to confirm the gunman’s full identity and locate him. If anyone has information about Jose, the white Acura, the pickup truck, or the events on Vultee Boulevard that night, please come forward.
