Ridgway spoke with ABC News affiliate KOMO reporter Charlie Harger in an exclusive interview . He said he wants to help the victims' families find their remains and closure.
"You can't go back and change the past; it's over with," Ridgway said to KOMO. "All we can do is try to make it better."
Ridgway confessed to picking up prostitutes and runaways in the 1980s and 1990s in Washington state. He would strangle them during sex, according to his confession, and dump their bodies near the Green River.
Ridgway pleaded guilty to 49 murders and is serving life in prison for those. He said the actual number is closer to 75 or 80, KOMO reports.
