DNA Testing Access 2011-2

__How DNA testing helped Weimer:__

 * A DNA test revealed that the blood on her muddy shirt belonged to her boyfriend.
 * A DNA test also revealed that the sweat shirt and bandanna found on the scene did not belong to Weimer or anyone else tested whose DNA was tested.

With this information, Weimer can persuade the jury using these facts to make a point that she did not do it and there is no evidence to say she did.
