OAKLAND, Calif. (KRON) – America’s oldest Hispanic civil rights organization wants the FBI to investigate the death of Mario Gonzalez.

On Friday the League of United Latin American Citizens sent a letter to U.S. Attorney General Merrick Garland calling for a federal investigation into the death of Gonzalez.

Back on April 19, Gonzalez died during a struggle with Alameda police.

Police bodycam video shows officers pinning Gonzalez on the ground, while kneeling on his back, neck, and shoulder.

Police say he suffered a medical emergency during the struggle, but his family says he was murdered.

Three officers are now on leave amid the investigation.

An autopsy into Gonzalez’s death has not been released.
