Michael James Mays was shot dead July 9 outside the restaurant, 1394 S. West Temple, during an altercation with off-duty security guard George Harrison.

In a statement released Thursday, Salt Lake County prosectors wrote that Harrison had good reason to believe he was in danger when he shot Mays.

"Mr. Harrison believed that Mr. Mays was reaching for a gun to shoot him," the release states. "Under the circumstances of Mr. May's verbal threats, aggressive approach toward Mr. Harrison, and action of lifting his shirt and reaching his hand toward his waistband, Mr. Harrison's belief was reasonable. The Salt Lake County District Attorneys' Office therefore declines to file any charges against Mr. Harrison arising out of this incident."
