TOLEDO, Ohio (AP) — A man who spent 20 years on death row before his sentence was overturned was hospitalized Thursday, just hours before he planned to enter a plea that would have freed him.

Ken Richey, 43, had been expected to plead no contest in a court hearing later Thursday and be sentenced to time served in the 1986 death of a toddler in an apartment fire.

His attorney, Ken Parsigian, said Richey was getting a heart catheter, but he was unsure what his client's medical condition was.

"It's serious enough that he clearly won't be available today," Parsigian said. "The good news is thank goodness it happened now, when he was close to a hospital."

Richey had heart problems in the past and was taking nitroglycerin tablets as treatment, Parsigian said.

The hearing was postponed until Jan. 8, though his lawyer said it could be held sooner.

"This is just a delay. What are you going to do?" Parsigian said. "As soon as he's well enough, we'll go back and get this done."

Richey, a U.S.-British citizen whose death sentence was overturned earlier this year, agreed to enter the plea deal Thursday that would allow him to go home to his native Scotland.

"Kenny spent so many Christmases away from his family," Parsigian said. "This one was going to be so special."

He was to have entered no contest pleas to attempted involuntary manslaughter, child endangering and breaking and entering, the lawyer said.

Richey was originally convicted of setting a fire that killed 2-year-old Cynthia Collins in 1986. He stayed on death row, once coming within an hour of being executed, until a federal appeals court determined in August that his lawyers mishandled his case.

The state was set to try him again in March and to seek another death sentence.

Instead, Richey had planned to plead no contest to the state's charge that he told the toddler's mother he would baby-sit the girl, but that he didn't and left her in harm's way, Parsigian said.

"We would never agree to anything on murder or arson or a guilty plea," he said.

For Richey, Thursday was supposed to be a day he has dreamed about.

"You've got to try to not lose hope," he said in a November interview with The Associated Press. "I got that way myself, almost, a couple of times."

Richey had planned to share a celebratory beer or two with his brother, who still lives in Ohio, before leaving for Scotland on Friday to spend Christmas with his mother.

It was not immediately clear how long he would be hospitalized.

While Richey's case has generated limited interest in Ohio, his name is a familiar one in Britain. He has drawn support from members of the British Parliament and the late Pope John Paul II.

"To be honest we have had one step forward and two steps back in this case and I wondered if this day would ever come," said Scottish lawmaker Alistair Carmichael, who has campaigned for Richey's release.
