THE heartbroken brother of a mum slaughtered alongside her new lover has slammed her twisted husband for “robbing five kids of their parents”.
Rhys Hancock, 40, yesterday admitted stabbing wife Helen Hancock, 39, and dad-of-two Martin Griffiths, 48, to death after discovering their relationship.
The mum-of-three’s brother Dave Almey has now blasted the evil headteacher over the brutal New Year’s Day slaying in Duffield, Derbys.
He told The Sun Online: “I wondered what had happened there and then got a sense that something horrible had happened to Helen.
“I didn’t go round there but I soon found out. It was a dreadful shock. What he did was sickening and so sad.
“He’s killed two innocent people and robbed five children of their parents.”
Dave said the three children know they have “lost their mummy and can’t see their daddy” but are not aware why.
He added: “They miss Helen so much, they had fun times together and she adored them.”
The brother also revealed how just two days before killing, Hancock had dropped flowers at Helen’s parents home on the former couple’s tenth wedding anniversary.
But he later returned to take the bouquet back – with Dave fearing he may have launched into the frenzied knife attack as Helen and Martin were spending the date together.
The designer said: “He left the flowers with our mum and dad and they were going to give them to her. I happened to be there at the time and we just said hello. He seemed OK.
“But the next day he came round and asked for the flowers back and took them away. I wasn’t at the house then but when my parents told me we all thought it very odd thing to do, like something had rattled him and he didn’t want her to have them.
“What went through his head and made him flip like that, I don’t know. But it may have been because it was his 10th wedding anniversary and his wife was spending it with another man although they were separated. He went totally crazy.
“He knew Helen had plans because she had left the children with his mum for the night. I think he had found out that Martin was on the scene just the day or a few days before.”
Hancock, was appointed last year as the headteacher at Stanton Vale Special School in nearby Long Eaton, killed the pair after discovering Helen’s new relationship with Martin.
She had ended her marriage to Hancock several months before and was living in the three-bedroom family home.
Friends have described Hancock as a “Jekyll and Hyde” character who refused to let his estranged wife move on.
The mum-of-three even got a restraining order against her headteacher husband.
And Dave claims he left Helen fearing for her safety – forcing her to take out a restraining order against Hancock.
He added: “There had been a few problems in the past and Helen had called the police.
“He had never been violent to her or attacked her, as far as we were aware, but he used to shout at her and threaten her and during the arguments she was concerned for her own safety and the children’s wellbeing so police were involved.
“He moved away and got his own place for a bit and then he lived with his mother.”
On the day of the attack, Hancock’s mum phoned police to warn them he had taken two knives and was “in distress” due to the discovery.
She said he seemed “calm” but she was concerned he was going to do something because he had said earlier he “felt like killing them”.
Hancock had also called 999 to warn them he was on the way to his former marital home.
Horrified neighbours heard someone yell: “They’re dead! They’re dead! What have you f***ing done?” at about 3am on New Year’s Day.
Police were then scrambled to the home where they found Helen and dad-of-two Martin gravely injured.
Paramedics battled for 15 minutes to save Helen but she was declared dead at the scene.
Mum-of-three Helen was found so brutally stabbed the knife – including blade and handle – were lodged in her body.
Hancock yesterday pleaded guilty to two counts of murder via video link at Derby Crown Court and will be sentenced at a later date.
The court heard previously how Helen had suffered “defence injuries” during the attack.
Derbyshire Constabulary referred itself to Britain’s police watchdog the IOPC “due to contact between Mrs Hancock and officers prior to the incident”.
Following yesterday’s guilty pleas, Dave said: “He’s crazy and I’m utterly disgusted with what he did to Helen. She was my kid sister, we were close and I really miss her.
“I hope he spends the rest of his life in jail. I was always a bit wary of him. I can’t pinpoint it but I just got bad vibes, there was something about him that gave me the creeps.
“He couldn’t handle the fact that Helen had found a new partner and that’s why he killed her and Martin too. He was riddled with envy and couldn’t bear the thought of her being with another man.
“I hadn’t met him but I was aware that she had someone new in her life and they were very happy.
“Rhys was so jealous and just couldn’t let go of the situation, he couldn’t deal with it.”
Martin, a dad to a 13-year-old girl and son, nine, separated from his wife Claire last year.
He was a former director of a marketing company and described himself on as a “dad and best friend to two beautiful children”.
In a statement Claire, 40, said: “I’m absolutely devastated for me, my children and all involved.”
In the statement, his family added: “Martin was a lovely dad, husband, son, brother and uncle, who had a passion for adventure, running and a love of animals.
“He enjoyed travelling the world, mountain climbing and spending time with his two children.”
