Caroline Crouch's husband is pleading for a prison transfer because he "fears for his life" after being attacked by a fellow inmate in a Greek jail.
Babis Anagnostopoulos, 34, was sentenced to life for killing his British-born partner Caroline in front of their 11-month-old daughter at their Athens home in May last year.
He claimed the 20-year-old died in a botched armed robbery only to eventually admit to a "crime of passion" after she had asked him for a divorce.
Anagnostopoulos' lawyer, Alexandros Papaioannidis, recently said his client had been attacked by a prisoner who admitted he wanted to murder him.
The killer was moved from Athens’ ultra-secure Korydallos prison to the Malandrinos facility.
But he has now applied to return to Korydallos due to security fears, reports ANT1 News.
A document put forward to the prosecutor on June 1 says: "My possible transfer to another Detention Center, implies that it will mean with absolute certainty my position at risk, with a threat to my physical integrity and my own life.
"The above is not reinforced by the fact that the case for which I am accused concerns the media and the public, reinforcing the feeling of killing me and even my inmates."
Anagnostopoulos cited "humanitarian and primarily personal security reasons", reports ProtoThema.
He also referred to himself as a "model prisoner", saying he acts as a mediator when other inmates are fighting.
Immediately after murdering his wife on May 11, 2021, Anagnostopoulos spun a web of lies to confuse investigators and avoid punishment.
The day after she was found dead, he told TV crews: "I wish no-one ever goes through what we went through last night. It was a nightmare.
"We begged the thieves not to harm us. We told them where the money was and asked them to leave us alone. The police will catch them."
Investigators carried out an eight-hour interrogation and Anagnostopoulos cracked, admitting to killing Caroline when she told him to leave the house after an argument.
They said Anagnostopoulos admitted he killed his wife in front of their daughter then strangled the family's dog as he tried to make it look like a robbery gone wrong.
He faced four counts: premeditated murder, animal abuse, perverting the course of justice and lying to authorities. He was found guilty of all counts.
In addition to life in prison he was handed an extra eleven years and six months in prison for the brutal murder of dog Roxy and deliberately perverting the course of justice.
