than the charge implies, he still became a target. rafael gonzalez threw the first punch. >> kind of like slow motion coming right at my face and i can't do anything about it. everything else just kind of seemed secondary to just me protecting, you know, the vital parts. >> deany nava also joined in on the attack. >> something must have happened because the next thing i know i'm lying on the ground in a pool of blood and just kind of coming in and out of consciousness. and i well remember waking up in the ambulance. >> sergeant rames is preparing a case against nava and gonzalez to present to the district attorney. >> it's an aggravated assault because they beat him unconscious and then continued to beat him afterwards. >> a conviction for either man does not require olson's cooperation. but if prosecutors have it, they will be more likely to take the case.
