A HEADTEACHER has admitted murdering his wife and her lover in a brutal love triangle bloodbath.
Rhys Hancock, 40, stabbed wife Helen Hancock, 39, and dad-of-two Martin Griffiths, 48, to death after discovering their relationship.
The headteacher was arrested at the scene in Duffield, Derbys, after the New Year’s Day horror when he called 999 himself.
Mum-of-three Helen was found so brutally stabbed the knife – including blade and handle – were lodged in her body.
Hancock’s mum had called cops herself to warn them he was heading to his estranged wife’s home armed with two knives.
He has now pleaded guilty to two counts of murder via video link at Derby Crown Court and will be sentenced at a later date.
Hancock, was appointed last year as the headteacher at Stanton Vale Special School in nearby Long Eaton, launched into the frenzied knife attack 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.
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”.
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.
Prosecutor Jeanette Stevenson said at an earlier hearing: “He found out on Boxing Day that his wife was seeing another man.
“He left his mothers address, where his children were also staying, with two knives. His mother said he felt like killing them.
“The police tried to contact Mrs Hancock but they could only reach her answerphone.
“Police received another 999 call from Mr Hancock saying he had murdered his wife and that the children were safe at his mother’s house.”
An inquest heard previously how Helen had suffered “defence injuries” during the attack.
Derbyshire’s Senior Coroner Dr Robert Hunter said: “Helen Hancock had suffered multiple stab wounds, some of which indicated the use of severe force.
“A knife was recovered from the abdomen. The whole of the knife being within the body.”
Derbyshire Constabulary referred itself to Britain’s police watchdog the IOPC “due to contact between Mrs Hancock and officers prior to the incident”.
Paying tribute to Helen previously, her family said: “We are devastated at the loss of Helen who was a lovely, beautiful, friendly, bubbly and social person.
“We would like to thank people for allowing us privacy at this most difficult of times.”
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.
