The FBI admitted it had no other suspects, and the investigation made little progress until early 1997, when two more bombings took place at an abortion clinic and a lesbian nightclub, both in the Atlanta area. Similarities in the bomb design allowed investigators to conclude that this was the work of the same perpetrator. One more bombing of an abortion clinic, this time in Birmingham, Alabama, which killed a policeman working as a security guard and seriously injured nurse Emily Lyons, gave the FBI crucial clues including a partial license plate.
The plate and other clues led the FBI to identify Eric Robert Rudolph as a suspect. Rudolph eluded capture and became a fugitive; officials believed he had disappeared into the rugged southern Appalachian Mountains, familiar from his youth. On May 5, 1998, the FBI named him as one of its ten most wanted fugitives and offered a $1,000,000 reward for information leading directly to his arrest. On October 14, 1998, the Department of Justice formally named Rudolph as its suspect in all four bombings.
After more than five years on the run, Rudolph was arrested on May 31, 2003, in Murphy, North Carolina. On April 8, 2005, the government announced Rudolph would plead guilty to all four bombings, including the Centennial Olympic Park attack.
