Arthur Bremer in custody 1972.

It has been 42 years since 21-year-old busboy Arthur Herman Bremer leveled his .38 revolver at Alabama Gov. George Wallace as the presidential hopeful campaigned at a shopping mall in Laurel, Maryland. Bremer squeezed the trigger, hitting Wallace five times and wounding three others.

The shooting left Wallace paralyzed and in pain for the rest of his life, effectively ending the presidential campaign of the man biographers have called "the most influential loser" in 20th-century American politics.

For his crime, Bremer – who had originally planned to assassinate President Richard Nixon but settled on Wallace because he thought security around the president was too tight – was sentenced to 53 years in prison. With good behavior time factored in, Bremer served 35 years and was released from the state penitentiary in Hagerstown, Maryland in the pre-dawn hours of Nov. 9, 2007. He was 57 years old.

Where is he now?

David Blumberg, chairman of Maryland Parole Commission, said Bremer now keeps a low profile.

"Even though his charge was high-profile, his discharge has certainly not been," he said.

Blumberg said Bremer lives in Cumberland, Maryland, where he has resided since his release. He has a verified home plan and a steady job, Blumberg added.

"So far, we've had absolutely no trouble what so ever," he said. "I've seen him a couple of times. Talked to him. He just stays away from the limelight."

Bremer was sentenced to 63 years before it was reduced to 53 years on appeal. He was not paroled, Blumberg said, rather he was freed as part of the state's mandatory release program that factors in good behavior and other matters.

Bremer regularly sees parole and probation agents and will remain under supervision until June 15, 2025, when he will be 75 years old. He is barred from attending any political events and is required to wear an electronic monitor that allows authorities to track his movements.

Wallace, who died in 1998, said he forgave Bremer and wrote to him in prison. Bremer has never spoken publicly about the shooting.
