Detectives have been given another 12 hours to question a BBC presenter who said he killed his terminally ill lover.
Ray Gosling, 70, was arrested on Wednesday morning after he told a BBC documentary he had smothered the man, who he said was dying of Aids.
Mr Gosling's solicitor said his client had still not named the individual to police.
Officers have until about 1945 GMT before they must seek a new extension.
Mr Gosling's solicitor Digby Johnson said on Wednesday night: "There's no more stressful situation."
"He is 70 years of age and he's in custody for a very serious matter and inevitably that is stressful."
Mr Gosling was arrested on suspicion of murder after his comments were aired on the BBC's Inside Out programme on Monday.
Police said he remained in custody and confirmed there had been no charges.
Mr Gosling could be detained without charge for a total of 96 hours.
"What he is facing here is a charge for which if he is convicted the court can only pass one sentence and that is of life imprisonment," Mr Johnson said.
"It would appear it will be a complex inquiry, the police are interviewing a number of witnesses and going through a lot of documents.
"He now has to take time to order his thoughts and emotions," Mr Johnson said.
Asked whether his client had made the whole story up Mr Digby added: "It has been said and it is something about which there has been some speculation."
The Nottingham filmmaker said he had made a pact with his lover to act if his suffering increased.
Mr Gosling has previously said he would not name his lover or say when the incident took place.
He said he was aware of the possible consequences and had no regrets.
In the film, which was broadcast on Monday, he said: "It's a terrible situation. I loved him to bits.
"We had a pact - he said if the pain gets bad and if nothing can be done, don't let him linger on.
"I don't think it's a crime."
"I picked up the pillow and smothered him until he was dead. When you love someone, it is difficult to see them suffer."
