The son of missing woman Sarah Wellgreen has released a heartbreaking message for her birthday today.

Lewis Burdett released a statement through the Search for Sarah Wellgreen Facebook page, which is run by those coordinating the volunteer searches.

The emotional post read: "I just wanted to to say happy birthday to the most amazing woman I have ever known, my mum Sarah Wellgreen.

"We all miss you so much, all of our family will still be celebrating your special day and we always will.

"We all love you so much mum and wish you were here to spend this day with us."

Mr Burdett's heartfelt message came just hours after Neil James, her partner, posted his own birthday wishes, once again appealing to anyone with information to step forward.

He wrote: "Happy Birthday to our beautiful, loving mother of five wonderful children, a distraught mum’s missing daughter and totally adorable to all that know our Sarah Jane Wellgreen - we all love and miss you and wish we could share your birthday today with you in person.

"Please anyone, if you could just help in anyway you can, please anything you can do! How can you....?

"What with the amazing efforts of Kent & Essex Police, in conjunction with the ‘Searching for Sarah Wellgreen’ Facebook page (please join and SHARE) along with compassionate and caring local volunteers (thank you all) to help us bring Sarah back where she belongs - with all of us, but MOST importantly with her loving mum and five CHILDREN as well as Sarah’s friends, my children and everyone that knows and loves Sarah."

Sarah has now been missing for more than two months and has had no contact with her family since.

She was last seen in the Bazes Shaw area of New Ash Green on October 9. Her disappearance is being treated as a potential murder by investigators.
