Evans' final arrest was on May 11, 1985 for harboring Marilyn Jean Buck, a fugitive in the 1981 Brinks armored truck robbery case, in which two police officers and a guard were murdered. At the time of her arrest, Evans was wearing a wig and glasses to disguise herself. The FBI agents obtained from her purse a Browning 9mm pistol and false documents with the name of Rebecca Ann Morgan, Christine Johnson, and Louise Robinett. The FBI was able to trace the gun to Louisiana, where Linda Evans was found to have purchased four firearms and three boxes of ammunition from three separate businesses under the false identity of Louise Robinett. Having purchased the four guns under a false identification, Evans was charged with eleven violations of the Gun Control Act of 1968. From March 16 to March 20, 1987 she was tried before a jury. Along with the eleven violations charges and housing a fugitive, she was also charged for terrorist actions after 740 pounds of dynamite were found in her apartment along with evidence of a plan to target the U.S Capitol Building, the National War College, the Navy Yard Computer Center, the Navy Yard Officers Club, Israeli Aircraft Industries, the FBI and the New York Patrolman's Benevolent Association. On March 20, 1987 she was found guilty of all charges and was sentenced to 40 years in prison.
