Holly Dunn is the lone survivor of notorious serial killer Ángel Maturino Reséndiz, also known as the "Railroad Killer."

On Aug. 28, 1997, during her junior year at the University of Kentucky, Holly Dunn and her boyfriend, Chris Maier, were attacked by the Railroad Killer as they walked along railroad tracks after a party.

The ‘Railroad Killer’

Reséndiz was a Mexican serial killer and rapist who also went by the alias Rafael Resendez-Ramirez. Active in the 1990s, Reséndiz's crime spree spanned multiple U.S. states, such as Texas, Kentucky and Illinois, and he was known for using the railways for transportation.

He roamed the country by freight train and landed himself on the FBI's Most Wanted list.

Reséndiz assaulted and killed Maier, but Dunn miraculously survived the attack despite being raped and severely beaten. "Holly faced a shattered jaw, enduring a month with her mouth wired shut, along with a fractured eye socket and numerous cuts to her face and head," reads the Holly K. Dunn website.

When Reséndiz was arrested, Dunn was the star witness in his trial. On May 17, 1999, following 10 hours of deliberation, the jury found Angel Maturino Reséndiz guilty of first-degree, premeditated murder. Despite last-day appeals from his legal team, the Railroad Killer received a death sentence and was executed in 2006.

Before his execution, Reséndiz said aloud, "I deserve what I am getting" and "Lord, forgive me. Lord, forgive me" before acknowledging his family watching through a window.

"I want to ask if it is in your heart to forgive me," he said to the relatives of victims in another room. "You don't have to. I know I allowed the devil to rule my life."

"I thank God for having patience for me. I don't deserve to cause you pain. You did not deserve this. I deserve what I am getting," Reséndiz said.

Shortly before his execution on June 27, 2006, Reséndiz confessed to additional murders beyond the known nine at the time of the trial. Authorities linked him to at least 15 homicides across six states: Texas, Kentucky, Georgia, Illinois, Florida, and California.
