An Oklahoma City couple is hoping a case 600 miles from here will finally help solve their daughters' slayings.
Cheryl Genzer and Lisa Pennington disappeared in September of 1987 after leaving the state fair. Their bodies were found in a shallow grave almost a month later.
Lane Henley was charged with the killings but was later released when a star witness changed his story.
Since then, two of his girlfriends have also turned up dead. In 2000, Molly Keahey, was found shot to death and buried in a shallow grave. Keahey's murder remains unsolved.
The most recent died in a trailer fire in Alamogordo, N.M., last month. Police said the fire appears to be an accident.
For Charlotte and Rocky Pennington, waiting for justice is literally killing them. Charlotte recently suffered her fourth heart attack and Rocky is waiting on a liver transplant.
"I'm hoping and praying that somebody will now come forward and stop this man," Charlotte said.
"It's killing us and one thing we've always said we would like to have at least seen him locked up before we're gone," Rocky said. "Knowing we can go in peace a little bit better, knowing he's still out here laughing at everybody, walking the street, that ain't right."
"I'd like to see murder charges filed on him four times and took off the street for the rest of his life." Rocky said.
The Penningtons admit that likely won't happen unless people who know what happened start talking.
"Without some information from somebody information of any kind, he's going to go out and do it again," Charlotte said.
The state fair is one of the last places the sisters were seen alive.
