The case dates back to 1996, when a man was discovered shot to death and buried in a shallow grave, a brutal crime that has remained unsolved for a generation. Now, investigators hope that this AI-powered age progression photo will generate new leads and finally bring a long-awaited resolution.

The 1996 Murder of Alfonso Reyes Martinez

On May 20, 1996, the body of Alfonso Reyes Martinez was found near the Alexander Valley Bridge, located north of Healdsburg. The Sheriff's Office described his death as a "brutal murder." For years, detectives worked the case, eventually identifying a primary suspect but were unable to locate him.

While the prime suspect remains at large, authorities were successful in convicting another individual as an accessory to Martinez's murder, confirming that others were involved in the crime and its aftermath.

Who is Suspect Antonio Bravo Marquez?

Investigators identified the suspected killer as Antonio Bravo Marquez. At the time of the homicide, Marquez worked as a vineyard laborer and was known to live in a transient encampment near Highway 128 and Alexander Valley Road. Now 61 years old, Marquez has also used aliases, including Antonio Brava.

His physical description from 1996 is as follows:

• Height: 5 feet 3 inches
• Build: Medium
• Hair: Short and black
• Eyes: Brown
• Other: May have a light mustache

He drove a distinctive vehicle: a white or tan 1973 Ford Maverick with a brown vinyl top.

A Renewed Call for Public Assistance

The Sheriff's Office is making a direct appeal to the public for any information that could lead to Marquez's whereabouts. "If you know something—even if it seems small—now is that time to come forward," the department stated in a release. They believe someone, somewhere has information that could be the final piece of the puzzle.
