Jerry Gonzalez, his brother says, “No medical problems, 26 year old man, healthy man. How the hell do you die?”

The family told KPIX 5 that officers were called to the area to investigate a possible theft.

According to Alameda Police, as they tried to handcuff Gonzalez, a scuffle ensued and Gonzalez died while in police custody.

“We know there was no scuffle because Mario was not a violent person,” Jerry Gonzalez told those gathered at the vigil

The Gonzalez family is demanding transparency in the investigation, beginning with the release of body cam footage. People at the vigil said they just can’t trust the police’s version of story.

George Galvis, a community organizer says, “If you take a look at the police report, it looks almost identical to the same police report, in the case of George Floyd.”

Alameda Mayor Marilyn Ezzy Ashcraft was also at the vigil. She expects police to release the bodycam footage sometime next week and admits, Alameda needs to do better.

“I’m calling for an independent investigation in addition to the Sheriff’s Office. I’m just heartsick to see this young man die. It should’ve never happened,” Ashcraft said.
