A man, Gregory Calvin King, 27, has been arrested and indicted by tehe FBI on felony charges by a federal grand jury in San Francisco.
Calvin King, arrested on Aug. 19 in Texas, was indicted for sending over 20,000 violent, offensive, bizarre, and profanity-laced tweets - including personal attacks - to the Twitter account of Marissa Mayer, Google's vice president of local, maps and location services - between November 2010 and Aug. 19.
He was charged with threats transmitted through interstate communication and harassing communications. If convicted, he could face up to five years in prison for the first count and up to two years in prison for the second count, The San Francisco Examiner reported.
The indictment mentions Twitter postings to Mayer on Aug. 14 saying "IM SURE YOU THINK IM SERIOUS AND I'LL F****** SHOOT YOU" and "I REALLY THINK I NEED TO SHOOT SOMEONE TO EVEN MY F****** SCORE."
Other posts on King's Twitter feed included "I should f****** shoot your ass marissa."
San Francisco FBI spokeswoman Julie Sohn said Monday "there is no known connection between King and the Google executive."
In some of his Twitter posts, King accused Mayer of having him falsely arrested and being associated with a group that tried to infect him with HIV "in powder form." He also made derogatory statements about Jews, blacks and Latinos.
A future court date has not yet been set, and attorneys for King were not immediately available for comment. A Google spokesperson also did not immediately respond.
