I do not believe Valve had much control over that. They needed to report it (failure to do so might get them in trouble with regulators, insurance, and all that crap), and once they do they don't get any say in how the investigation or prosecution is handled. Even if Newell refused to testify, chances are this wouldn't hinder prosecution very much... plenty of other evidence to stick it to the kid.
