In this photo provided by Washington State Department of Corrections, Larry Gillette is shown. FBI agents arrested 53-year-old Gillette, of Shelton, on Monday, April 28, 2014, as he met with an undercover agent and attempted to ignite a car bomb. The bomb was inoperable. The U.S. attorney's office says Gillette was scheduled to appear in federal court in Tacoma on Tuesday on charges of solicitation to commit a crime of violence and being a felon in possession of a firearm. Authorities say the FBI learned about the plot while Gillette was serving a prison sentence for identity theft. An undercover agent befriended him after his April 14 release.
