A man accused of planning to shoot people at the Super Bowl was indicted on six counts of sending threatening communications, according to court documents filed Tuesday in federal court.

Kurt William Havelock, 35, turned himself in to authorities Feb. 3 after driving within sight of University of Phoenix Stadium during the Super Bowl with a rifle and 200 rounds of ammunition. He said he changed his mind.

Havelock told authorities he was upset that the city of Tempe denied him a liquor license application for a Halloween-themed bar.

Before the planned attack, the indictment said, Havelock sent several letters to Web sites and news organizations. Havelock's writings included an eight-page manifesto in which he warned of an "econopolitical confrontation," according to the FBI.

A phone message and e-mail sent to Havelock's federal public defender Jeffrey Williams were not immediately returned Tuesday evening.
