After the interview, Hawkins went to the Shasta County Sheriff's office to meet with police investigators, the Redding Police Department said. As a result of Hawkins' confession, Redding police immediately searched out and rounded up two of his alleged accomplices: 46-year-old Shanna Culver and her brother, 45-year-old Curtis Culver.
A hiker found McAllister's remains a year later, police said.
Hawkins said the guilt ate away at him over the years.
He said, "God and Christ and these things that have happened over the course of 25 years have pushed me and pushed me to do the right thing".
Hawkins and the Culvers have since been arrested and are being held in Shasta County jail. "I know the wrong can't be changed but this is the closest I can come to doing the right thing ..."
In 1993, investigators learned Hawkins and the Culvers were the last people to see the victim alive, but they denied any involvement in his disappearance, and did not have any information about his whereabouts, the release said. Both were arraigned in Shasta County Superior Court on Friday afternoon and charged with murder, robbery, and two special circumstances: lying in wait and murder during the commission of a robbery, Shasta County District Attorney Stephanie Bridgett said.
"Every minute of every day has been a nightmare", Hawkins said. Hawkins continued, saying that there hadn't been a moment where he hadn't been remorseful for what he had done.

McAlister drove the group to a rural area in Shingletown, the complaint says. According to Hawkins' KRCR interview, he searched out McAlister's family and tried to own up to his actions on numerous occasions, but it just never happened. Once they got there, the trio allegedly made a decision to kill McAlister, stabbing him to death leaving his body in the woods.
Hawkins claimed Curtis Culver, who was 21, stabbed McAlister inside the auto, and that Hawkins later stabbed McAlister outside the vehicle, the complaint says. Police arrested the Culver siblings on Wednesday in Red Bluff, officials said.
During the interview with the TV station, Hawkins shed tears and appeared shaken.
When asked why he was coming forward now, he said: "I've been through hell my whole life because of this".
During the interview, Hawkins also said he even reached out to McAlister's family a year ago and that he wanted to confess to his crime in front of them.
Redding Police Captain Eric Wallace said multiple investigators took on the case over the years, trying multiple leads-with little to show for all their work.
