Devastated loved ones have previously paid emotional tribute to the family.
The sister of mum, Emma, and family of dad, Robert, have said how devoted they were to each.
‘Kelly was a wonderful and special person. She was kind, caring, funny and always smiling with an amazing love for life,’ said Emma.
‘Kelly was a dedicated and loving mother and adored Rob and her two beautiful children. She had many friends and was devoted to her friends and family.
‘Kelly will be missed by so many people and has left a hole in our hearts that will never be filled.’
Robert’s family said: ‘Robert was a man with a loving, caring young family. He had a beautiful partner Kelly and daughters Ava and Lexi, who he cared for deeply and who cared for him.
‘He was a quiet and thoughtful son and brother as well, always there to help when he was needed. We are devastated and bewildered at this most difficult of times.’
Police are not looking for anyone in connection with the deaths.
