Man charged with murder in Bristol
On Saturday June 30th 58 year old Judith Ege died after she was found with stab wounds at an address on Highbury Rd in Horfield, Bristol.
Her family have released this tribute to her:
"Judy touched the lives of everyone she met and left them feeling they were a better person for having met her. A gifted and talented special needs teacher she taught those children the rest of society had often written off. All of her working life was spent developing children with complex special needs. Although retired such was her ability and talent that she was persuaded to come out of retirement to help in the restructuring of a special needs school in Kuwait where she would have been teaching special needs pupils and special needs teachers. She will be sorely missed by those children she taught and those she was going to teach.
Family and friends were in abundance and despite a very challenging work life no birthdays, weddings or other celebration was ever missed or forgotten. She made time for everybody and was happiest when making other people happy.
Judy was a beautiful woman inside and outside who always looked on the positive side of life and always put the needs of others before her own. "
38 year old Barach Bandavad has been charged with her murder. Bandavad, who was the ex partner of Judith Ege's step daughter, appeared before Bristol magistrates on Wednesday July 4th where he was remanded into custody to appear at Bristol Crown Court on Friday July 6th.
