Dwyer is a vegan activist who becomes a suspect in the murder case of food critic Vince Wagner when it is discovered she might have framed the person who is at that point considered the culprit, chef Antonio of Antonio's. She developed a hatred towards him when she found out that he would use beef broth in his veggie burgers to appease those complaining about the bland taste, a faux pas motivating her to start organizing boycotts against his restaurant before she went so far as to advocate any action that would put Antonio out of business. When Shawn and Gus additionally discover that one of her protests outside Antonio's took place on the night of the murder, they think they just found Wagner's killer and start celebrating. However, Juliet rains on their parade by informing them that someone completely different had been spotted the previous day discarding the poisonous mushrooms that killed Wagner, meaning that Dwyer is no longer considered a suspect and should be left alone.
