What happened to the individuals who pleaded innocent to the charges of witchcraft as opposed to those who pled guilty?

The answer seems to be that those who pleaded innocent were acquitted. Per Answers.com, "Nearly two hundred people were accused of practicing witchcraft in Salem during the summer of 1692. Twenty accused witches were executed, fifteen women and five men." This despite the facts that the accused had no right to legal counsel, and were presumed guilty.
