Robert Zimmerman Sr. and Gladys Zimmerman filed suit Monday in state circuit court, accusing Barr of trying to incite "a lynch mob to descend" and carry out "vigilante justice."
According to the suit, Barr published their address on Twitter March 29, 2012, a month after their son George Zimmerman killed Trayvon Martin, an unarmed black teenager in Sanford, but before his arrest. Their son did not live with them, nor did they have anything to do with the shooting, they point out.
It alleges that Barr's tweets forced them to go into hiding. They are seeking unspecified damages, accusing her of intentionally inflicting emotional distress.
They also allege that she violated Twitter's terms and conditions prohibiting publication of addresses and other confidential information. After the first tweet, the suit alleges, Barr followed up with others, including: "If Zimmerman isn't arrested I'll rt (re-tweet) his address again — maybe go 2 his house myself."
A jury acquitted Zimmerman of second degree murder.
A representative of Barr, who lives in Hawaii, was not immediately available for comment.
