The designer of the train that killed Lee Pomeroy in a frenzied 25-second attack does not deserve to live, said the widow in mourning for the victim.
Lana Pomeroy, 51, says Darren Pencille had taken her "soul mate".
Describing her "eternal loss," she told the Sunday Mirror, "He stole my precious life from my husband so that he would not live anymore."
"He does not deserve to live.
"Lee, I really miss my soulmate. He was an honest and honest man.
"He made sure that his family was always looked after and that he was the breadwinner. He was a very caring father, he loved his son and spoiled him a lot. But now he's gone.
Lana also gave a heartbreaking account of the attack, which was relayed to her by her son.
She compares it to a horror movie.
She tells how the 14-year-old, who can not be named for legal reasons, found Lee hit on the train, bleeding profusely.
In a heartbreaking tale, she reveals how the boy rocked his father and said, "Do not move, dad."
Lana was speaking after Pencille, 36, was jailed Friday at the Old Bailey for at least 28 years for murder.
Lana, born in Russia, feels guilty for not being able to prevent the fatal attack of January 4 this year.
She explains, "If I had been there, things might have been different. It's really hard to handle.
"I wanted to go on this trip, but I did not do it. It was after Christmas and we wanted to save money. "
Torn Lana also tells how fate cruelly put Lee and his son in the same train as Pencille.
The two men changed their plans at the last moment by choosing to take a train that arrived 10 minutes before the scheduled time.
They had left for Guildford, Surrey, London, one day before Lee's 52nd birthday.
He died after having problems with Pencille who was blocking the driveway. CCTV showed the pair insults.
As the row grew stronger and passed into another car, Pencille hit, stabbing Lee 18 times in 25 seconds.
Pencille, a former gang member who had a history of knife and knife offenses, ran away to the next stop.
His girlfriend, Chelsea Mitchell, 28, was found guilty of helping an offender after picking him up at Clandon Station after the attack.
The criminal past of Pencille has more than a dozen convictions.
He sliced the neck of a man on the cigarette paper.
It was also revealed that he had been seen by a psychiatrist barely 24 hours before the murder, but that he was considered "safe for himself or for others".
Fortunately, Lee's son did not witness the mortal wounds inflicted by Pencille.
Lana said, "He found his father sitting and holding his head, he noticed that his eye was very badly hurt and he asked him what had happened.
Lee replied, "Oh, he hit me." Then Lee got up, went to the doors and fell to the ground, blood flowing from his neck, bubbling like in a horror movie.
"He said," Do not move, daddy. " Our son had to call the ambulance because he was alone with his father.
"He tried to keep Lee on the ground and asked him not to move too much, hoping he would not lose more blood.
"While Lee was lying on the floor, there was a lot of blood. Our son called for help. Train the staff and the police tried to help.
"A railwayman even put his rider around Lee's neck to stop the blood.
"They were really trying to save Lee's life. An air ambulance arrived and they tried to resuscitate him.
"Our son was then taken off the train and did not see Lee's death.
"I received a call from the police about 30 minutes after it happened.
"The policewoman told me that she was with our son and that my husband was seriously injured after someone attacked him on a train." The paramedics were with him.
"It was a shock, but there was a hope that he was just hurt, not dead. My immediate reaction was to take our son and go to the hospital to see my husband.
"But the policewoman told me that she would take our son home." I had to wait an hour in the real agony of not knowing what was happening.
"They finally came and told me to sit down because they wanted to talk to me."
"I could not believe that my husband was dead. I did not stop repeating myself: "it can not be real".
"Our son did not know that his father was dead on the train either.
"The police stayed for hours because the pain of the loss was unbearable and shocking.
"Our son found it easier to mourn with his beloved beagle Benji.
"He spent two weeks in bed with his dog. It really helped him overcome defeat. "
Lana and Lee met in Moscow and she moved to Britain to be with him.
She said: "Lee was interested in Russian culture, history and classical music.
"His favorite composer was Shostakovich. He even learned Russian, but found it very difficult.
"We met in Moscow where I worked in fashion as the secretary of the famous designer Slava Zaitsev.
"I had a lot of friends and a big family, but I left everything to join Lee in Britain when we fell in love with each other.
"We had many common interests and our vision of the world and life were almost the same, so we could talk for hours about music, history, politics and social topics.
"I called him" computer boss "because he knew almost everything about everything. It was like a living encyclopedia of all the music ever created, from classical to rock or goth.
"He had a degree in art, he was a brilliant athlete and won many running events. He loved rugby and football.
"He also had a Bachelor of Science in Mathematics. Lee was very friendly to all people, regardless of color or race.
"He had friends from different backgrounds and different countries. He always intervened if people needed help in difficult situations.
"It is impossible to describe this eternal loss."
The senseless killing also had a profound effect on Lee's sister, Kim Pomeroy, who has a sanctuary for her beloved brother at home.
They were born one year apart at Bow, in East London, and were excellent playmates as they grew up.
Kim recounts how Lana and Lee chose to live in Surrey because it was safer than the capital.
Medical PA Kim, 51, also says Lee did not like confrontation, but he has always resisted tyrants.
She thinks that he only confronted Pencille because he thought his son was in danger.
Kim said, "He (Pencille) was aggressive and was trying to get into trouble after a very minor incident. Then he threatened Lee.
He said, "It will not end well. Put your hand on me.
"After enduring this for a while, Lee stood up and clenched his fist.
"But he did it because he saw this aggressive screaming man as a threat to his son.
"He got up because he wanted to get her away from her scared son. Lee was brave and that's why he's no longer there. His family came first, especially his son.
Kim also remembers when Lee was heroically attacked by a thief.
She said, "Several years ago, Lee was sitting in a cafe in London and he saw a man grabbing a woman's handbag.
Lee pursued and fought the thief's bag. That sums up my brother.
"He was very protective, especially of women and children.
"He was the kind of man who made the world a better place."
