Texas Confidential

Who Killed The Bookie's Wife?

(CBS) 
In September 2004, Bob was brought back to the U.S., pleaded guilty to passport and tax fraud, and was sentenced to 12 years in federal prison.

The only good news for Bob's daughters, who are now living in California, was that Bob was moved to a nearby prison. To this day, Niki and Ali say they till believe their father is innocent.

"It's just like me and Niki and our dad," says Ali. "That's what we consider our family," Niki adds.

The twins says they still have a strong relationship with their father.

48 Hours' last interview with Bob was from his prison cell in California. With the Dutch court ruling, that he could not be tried for Doris’ murder again, Schlesinger asked Bob that one, all-important question one last time.

"Did you hire Roger to kill Doris?" Schlesinger asked.

"No," Bob replied.

Asked if her hired anyone else or had anything to do with her death in a legal sense, Bob said no.

"And you say that now, even though you have that Dutch ruling in your hands?" Schlesinger asked.

"The ruling doesn't make a difference. The truth is only thing that really counts," Bob replied.

While Bob spends his time behind bars, federal prosecutors are likely to spend their time trying to figure out a way around the Dutch court ruling and prosecute him again for Doris' murder. And even Bob's own lawyers are betting they will.

"Your best guess, will Bob Angleton ever be a free man again?" Schlesinger asked Schneider.

"Probably not. If you put the numbers to it…. It’s a long shot," Schneider replied.

But Angleton’s daughters are still betting that their father will, one day, be free again.

"Do you think he'll be able to come to your weddings?" Schlesinger asked the sister.

"Oh, yeah. He will," Ali said. "I'll put it off for a while. Good excuse not to get married. Put it that way," Niki added.

"There's no way, there's no way I would get married without him there," Niki said. "It will all work out. It will."

Bob Angleton will be released from prison in 2014. The twins will be 30 years old. The U.S. Government says it has found a way to prosecute Angleton for murder after his release from prison. The only way he could avoid that is to leave the country again.
