The lawsuit cites Cooper's coverage of Peterson's trial and dozens of tweets about the incident in which the blogger allegedly promoted “debunked” conspiracy theories and questioned Pete's legitimacy based on her connection to Peterson and his father.

According to a screenshot in the lawsuit, Cooper published a petition in September calling for Peterson's release. On Sunday, the lawsuit says, Cooper tweeted the claim that the gun linked to the shooting was “missing.” The lawsuit argues that the gun is still in the possession of the Los Angeles Police Department.
