The family of jail inmate Ernest Marty Atencio has taken him off life support.
The military veteran was arrested last week for assault.
While he was being booked into the Fourth Avenue Jail, we're told he struggled with deputies who the family says used a Taser and then put him in a holding cell.
They also tell us Atencio stopped breathing and it took awhile for the jail staff to notice and get him to the hospital.
The Maricopa County Sheriff's Office is still investigating and has yet to comment despite repeated requests.
