Eric Rudolph (search) is charged with four bombings in Georgia and Alabama, including the explosion at Atlanta's Centennial Olympic Park (search) during the 1996 Summer Olympics. Some of the evidence authorities say link him to the bombings:
-- THE TRUCK: A truck matching one seen near the scene of the 1998 bombing at the New Women All Women clinic in Birmingham, Ala., was found days later near Murphy, N.C., the same town where Rudolph was captured. Authorities said the gray 1989 Nissan pickup truck was registered in Rudolph's name.
-- THE LOCKER: Authorities who searched a storage locker Rudolph rented in Murphy found nails like those used in the clinic bombs.
-- THE DEVICES: Some of the steel and nails used in the bombings were similar. All the bombs used nails in a design meant to maim people over a wide area. Investigators have matched the nails in the two abortion clinic bombings to nails found in a storage shed rented by Rudolph, a federal agent told The Associated Press on condition of anonymity.
The Olympic and Atlanta abortion clinic bombs had one-eighth-inch-thick steel plates, of the same general formulation, designed to direct the blasts, another agent said.
-- THE LETTERS: Letters were sent to at least two Atlanta media outlets stating the Birmingham bombing was carried out by the shadowy "Army of God." The same group claimed responsibility for the 1997 bombings at a women's clinic and gay nightclub in Atlanta.
-- THE GUN DEALER: A Tennessee gun dealer identified Rudolph as the man who bought 50 pounds of smokeless powder several years before the bombings. A senior law enforcement official said that powder was connected to the Olympic bomb.
