Antonio Ramos, a 27-year-old artist from Emeryville, California, was shot and killed on the morning of September 29, 2015, while working on a community mural under the Interstate 580 freeway in West Oakland. Ramos was part of the Oakland Superheroes Mural Project run by the nonprofit Attitudinal Healing Connection; he was painting with other artists when an altercation with an unidentified man escalated and Ramos was shot. He was taken to hospital but died of his wounds.

Witnesses said the assailant had been tampering with the artists’ equipment before the confrontation. The Oakland Police Department initially struggled to identify a suspect or motive. In November 2015, 20-year-old Marquise Holloway was arrested and charged in the killing; the gun used had been stolen weeks earlier from a U.S. Immigration and Customs Enforcement officer’s vehicle. Holloway later entered a no contest plea to first-degree murder and received a term of 25 years to life with possible parole under youthful offender provisions.

If anyone knew Antonio, worked on the mural, or saw activity under the I-580 that morning, please share what was seen or any information that could add context to the case.
