“After talking with my staff and reviewing the video, I was greatly disturbed by this unprovoked and senseless act of violence against an elderly community member. I immediately committed the full resources of the Sheriff’s Office Investigations Bureau,” said Alameda County Sheriff Greg Ahern.

The Alameda County District Attorney has charged Betancourt with attempted murder, assault with a deadly weapon and elder abuse. Anyone with additional information or video is asked to contact the Alameda County Sheriff’s Office.
