A wife has made a heart-rending plea to her missing husband as she begs him to come back home.
Mel Blyth reported husband Darren Blyth missing last Wednesday, after he failed to return to his Trimdon Station home from a trip out to take photographs at Hawthorn Dene.
Despite what police have called an "extensive investigation", popular biology teacher Darren, 55, is still missing, and his wife and children say they're deeply concerned about him.
On Monday, Mel, who has been with Darren for 27 years and together have nine-year-old daughter Abigail, made a direct appeal for him to come home.
In a handwritten note, the 53-year-old wrote: “To my darling husband Darren, if you are reading this then I want you to know that you are my entire world.
“You are the most beautiful, kind and generous soul I could ever wish to spend my life with, and nothing could ever replace my love for you. You are priceless.
“I will not rest until you return home safely to me, Abigail and your family who love you more than you could ever know.
“You are truly the most important person in my life and I need you back safely with me. I know how much you love us, and that is why I know you want to come home.
“I can’t express how elated that would make me feel, so please, please, come home where we can make you feel safe, happy and loved.”
Darren, who also has another daughter, Katrina Blyth, and is a granddad, teaches at Stokesley School & Sixth Form College where the head teacher, Hannah Millett, said staff and pupils hold him in high regard and are hoping for his safe return.
Daughter Katrina added: "Dad, the last thing you said to me was, ‘Thank you. It’s good to have people you can rely on.’
“There isn’t a problem that we can’t solve together as a family. We can get through anything as long as we’re together.
“Mel, Abigail, Alex, Tamzin, Sean and I just want you home safe. Please get in touch to let us know that you’re okay.
“We love you so much.”
Since Wednesday, police have been carrying out "extensive searches" across the east coast and surrounding areas and have followed up on a number of reported sightings of Darren, who was last seen on The Cleveland Way.
Survival expert Ray Mears, a family friend, has been helping with the search, while missing person posters have been placed around the Dene where he had been on Wednesday.
He is described as 5ft10, of slim build and with short grey hair, and was last seen wearing a black North Face coat and grey outdoor trousers.
Anybody with any information relating to Darren’s whereabouts is asked to contact Durham Constabulary on 101 as soon as possible.
