Thomas took off and was tackled, setting off the nearly 10-minute beating that allegedly led to his death.
Ramos is a 10-year veteran of the Fullerton Police, while Cicinelli has been an officer in Fullerton for 12 years.
The video ended with paramedics carrying Thomas' body to an ambulance, revealing a large blood stain on the spot where the altercation took place.
"We ran out of options so I got the end of my Taser and I probably ... I just start smashing his face to hell," Cicinelli said at the end of the July 5 video, according to the transcript provided by prosecutors to the Associated Press. "He was on something, 'cause the three of us couldn't even control him."
Thomas had no illicit drugs or alcohol in him at the time of the incident, according to the toxicology report.
If convicted, Cicinelli could face a maximum sentence of four years in prison and Ramos could be sentenced to life in prison.
