Evil dad Denis Beytula murdered his newborn son by stabbing him in cold blood as he lay sleeping in his Moses basket.

Instead of displaying fatherly love after the birth of little Andrei Stefan, control freak Beytula showed resentment towards him and his partner, Andreea Stefan.

A court heard that even before Andrei was born, Beytula had ominously warned: "If I cannot be a good father to him, he will not live, I gave him life and I will take life".

Just three weeks into his life, that chilling threat was to come true in horrific circumstances at the family home in Wallsend.

Beytula then turned his weapon on Andreea, who witnessed her baby's murder, and tried to kill her, stabbing her six times. She survived by sheer good fortune.

Prosecutor Nick Dry told Newcastle Crown Court Andrei had been born on September 11 but Beytula "showed a lack of interest and even detachment from his son", and "that lack of fatherly love and affection setting the tone for his son’s brief life", the court heard.

When they got home Beytula was resentful of the baby and his partner, choking her on one occasion and becoming convinced that she was planning to leave him and take up with another man, threatening to kill them both before he would allow that to happen.

On the evening of October 1, Beytula attempted to initiate sexual contact with his partner but the baby cried and Andreea went to tend to him.

Mr Dry added: "He then took a blue handled kitchen knife and placed the tip on Andreea’s stomach and threatened to kill her."

The next morning began with the defendant behaving as though nothing had happened and  wondering aloud why Andreea was not speaking to him before briefly leaving their flat.

When he returned in the early afternoon he was angry. In the kitchen, he took hold of the knife he had threatened his partner with the previous evening. He told Andreea that he loved her and that he only needed her smile.

Mr Dry said: "He then turned the knife toward himself and then attempted to hand it over to her and said, ‘ok if I can’t kill you because I love you, you kill me.’

"He then put the knife to his own wrist and made a superficial cut over the veins. He drew blood and scared Andreea, who begged him stop and tried to reason that if he did love her, he would not do that.

"Still holding the knife, Beytula then went to the bedroom where his son was sleeping and sat down on the bed. He was followed by Andreea and he asked her to go away, to the bathroom, on the pretence of getting him a dressing for his own superficial injury.

"At first, she refused, until he shouted at her and she edged away towards the bathroom. At that moment, she heard the defendant stand and she hurried back into the room to see him standing over the Moses basket, he then bringing the knife down quickly upon their baby son.

"Having inflicted fatal wounds upon him he then bore down on his partner, stabbing at her again and again. She struggled with him and managed to avoid some of the blows but still he drove the knife into her body repeatedly."

Having inflicted six wounds there was a lull when she begged him to call an ambulance. As if nothing had happened, he simply said that he would and went outside where he stood next to his car and called the police.

Mr Dry said: "He told them that he had killed his wife and child, stating that he had done so because Andreea had been making porn videos and taking cocaine, both claims for which there is no evidential foundation and which are thought to relate to his jealousy of a previous partner."

At almost exactly the same time, Andreea was making her own 999 call, begging for an ambulance and crying that she and her son were dying.

Police arrived found Andreea ashen-faced and covered in blood before finding Andrei, "stabbed, crying and bleeding to death in his Moses basket".

For four days, doctors fought to save Andrei but he died on October 6 as a result of the two stab wounds depriving his brain of oxygen.

One of those wounds had been delivered to the right side of his abdomen and pierced the cartilage of the rib cage before passing through the substance of the liver and exiting his back.

The other wound was also found to have passed clean through the right side of his body, puncturing his lung and again exiting through his back.

Andreea was found to have three deep wounds to the right side of her abdomen, two to her left side and one to her chest. There were three external lacerations of her liver, a laceration of the spleen and eleven lacerations of the intestines and digestive tract.  She also needed emergency surgery.

The court heard after meeting Andreea, who was a manager at Dominos Pizza, from the outset, Beytula was infatuated with her and also sexually obsessed with her.

Mr Dry said: "The first signs of a problem in the relationship arose when Andreea did not want to have sex when the defendant did. Whenever she said no he would appear insecure and have a tantrum, displaying emotional immaturity allied to brooding jealousy.

"Those personality traits quickly manifested themselves in controlling and coercive behaviour. He insisted on having access to his partner’s mobile phone, forced her to delete her Instagram account and criticised her for having male friends on Facebook.

"When Andreea was invited to attend an awards ceremony in London in connection with her employment, he stopped her from going. In the very early days of the relationship, a mutual friend warned Andreea and her mother against Mr Beytula’s coercive nature and behaviour towards his ex-partner, but tragically that warning was never heeded."

Andreea was also afraid he would find out that she drank alcohol and the impression formed by those close to her was that the defendant was a ‘control freak’.

Mr Dry added: "Examples of his insecurity contained within WhatsApp conversations include the defendant demanding access to his partner’s telephone passwords, alleging that positive feedback from her manager at work was sexually motivated and his refusal to believe, upon Andreea booking a massage, that the masseuse was female."

When Andreea fell pregnant in January, Beytula, who had said he wanted a baby girl with her mother's eyes, showed no understanding of her reduced interest in sex and instead became ever more insecure and angry, taking away presents that he had previously given her and sometimes breaking them.

Mr Dry said: "To the outside world, the defendant appeared to be a proud expectant father showing some enthusiasm for the impending birth, decorating the nursery and making expensive purchases.

"At the same time, however, he continued to be angered and increasingly consumed by his partner’s reduced enthusiasm for his sexual advances, those feelings fuelling the fires of utterly unfounded jealousy of other men.

"One such was: 'If I cannot be a good father to him, he will not live, I gave him life and I will take life'.

"In the weeks prior to the birth of Andrei he was particularly volatile, drinking whisky, crying, talking to God, smashing property up, speaking of his interest in the dark web and threatening to kill himself, taking up a knife on many occasions but never actually inflicting injury."

Beytula pleaded guilty to murder and attempted murder and Judge Paul Sloan QC sentenced him to life with a minimum term of 23 years before he can even be considered for parole.

Judge Sloan told him: "The victim, your newly born child, was particularly vulnerable and it took place in Andrei’s home, which should have provided a place of sanctuary.

“Andrei was an entirely innocent victim, as you well knew.”

Richard Fisher QC, defending, said Beytula, who has no previous convictions, is remorseful, had a difficult childhood and says the attack was not premeditated. The court heard he was suffering from a mild mental illness at the time.
