A grieving mother whose teenage daughter died from suspected carbon monoxide poisoning in a holiday lodge has demanded such properties be forced to have detectors fitted.Cherish Bean, 15, and her 17-year-old boyfriend Ethan Slater died on a visit to Little Eden Holiday Park near Bridlington, East Yorkshire in February.An inquest into their deaths held earlier this year at Hull Coroner's Court has not yet delivered a verdict but Humberside Police previously said carbon monoxide poisoning was a main line of inquiry.Devon Andrews, Cherish's mother, has now begun a petition to make carbon monoxide alarms compulsory in all holiday accommodation.Ms Andrews, from Sheffield, South Yorkshire, said: 'This petition is written by a mother whose heart has been broken forever. Carbon monoxide is a silent, preventable killer. No family should go away and not come home.'Stronger laws are needed to ensure all holiday accommodation has working carbon monoxide alarms to prevent further devastating loss.'Ms Andrews, 32, said her campaign had 'never been about politics' but to stop 'preventable deaths'.She added: 'Our petition aims to encourage greater public awareness and to open conversations around whether existing regulations and safety requirements go far enough to protect people staying away from home. Cherish Bean and Ethan Slater, aged 15 and 17, died on a family holiday from suspected carbon monoxide poisoning Cherish's mother Devon Andrews (right) has now begun a petition to make carbon monoxide alarms compulsory in all holiday accommodation'We believe that everyone should be able to go on holiday and return home safely to their families. Cherish was my world. We had the most incredible bond and she wasn't just my daughter, she was my best friend.'She was kind, funny, caring, talented and had the ability to light up any room she walked into.'Ethan was exactly the same. He was loved as one of our own and brought so much happiness into our lives. When we lost them, our family lost two beautiful young people with their entire futures ahead of them.'We are calling for stronger awareness and improved safety measures surrounding carbon monoxide monitoring within holiday accommodation, holiday lets, staycations and short-term rental properties.'For me, this campaign has never been about politics. It has always been about my daughter, Cherish, and her partner, Ethan. The purpose of all this is to help prevent other families from experiencing the devastation that we have endured.'A 41-year-old man had been arrested and released on bail as of March while three other men aged 27, 33 and 42 who were previously arrested remained on conditional bail.Before she died Cherish had complained to her mother of a headache before she went to bed in the lodge.Area coroner Paul Marks previously told the inquest at East Riding Coroner's Court: 'The family spent the night together and Cherish and Ethan were both fit and well.'Cherish left the family for the smaller cabin next door, with Ethan at 9pm to watch TV.'She returned to the main cabin at 9.50pm complaining of a headache, spoke with her mother and had Calpol as the family had no paracetamol.'Cherish went back to bed in the small lodge and texted her mother at 10.20pm to say goodnight and that she loved her. The circumstances were similar for Ethan, who went back to the cabin at a similar time.'The court also heard Cherish sent her mother a final message saying 'goodnight, I love you' before the pair died from suspected carbon monoxide poisoning.Since Cherish's death her father Grant Bean, 33, has had a whole back tattoo of his daughter inked in her memory.The father-of-three had four seven-hour tattoo sessions across four days to complete the metre-long artwork. Since his daugher's death, Cherish's father Grant Bean has had a metre-long tattoo of her inked on to his back Cherish had complained of a headache before she died in a holiday lodge and took Calpol for the painHe said: 'After losing Cherish I wanted to be able to carry her with me everywhere I go and although she is always in my heart a picture of her tattooed on me felt right.'Ms Andrews said her proposed carbon monoxide alarm law would be 'built on love' and not 'anger' - it has more than 6,200 signatures so far.She said: 'It is about remembering two wonderful young people, protecting future families, and making sure that Cherish and Ethan are never forgotten.'Carbon monoxide is often referred to as the silent killer because it cannot be seen, smelled or tasted. Yet the consequences can be catastrophic.'As a mother, I cannot change what happened to Cherish and Ethan. I cannot bring them back. But I can fight to ensure that their lives leave a legacy.'If sharing their story helps raise awareness, improves safety standards, or ultimately saves even one life, then their legacy will continue to make a difference.' Ms Andrews, pictured with Cherish, said she would fight to ensure her daughter and Ethan's lives left a legacyMs Andrews previously said she was 'shattered' by her daughter's death.She said: 'My perfect girl, my angel, has left this world and we are broken as a family. I am broken as a mother, and I will never ever be the same again.'If you know me, I live and breathe my babies, and we were away for a few nights making the best memories ever. We have had the best life together and it has been ripped from under us.'There are no words, I am shattered and will never recover. Hug your children tonight you do not know how lucky you are.'Ethan, bless you darling, such a good boy with a kind heart and I loved you like my own.'In a police-issued tribute Ethan's mother said: 'Ethan was the most beautiful young man to walk the earth. He was generous, loving, charming and kind.'He would help anyone and was a strong family man. He took care of himself and loved his mum, stepdad, brothers and sister.'There's not one person who would dislike him even if they tried. His smile was contagious, and he could light up any room he walked into.'Ethan, you will always be remembered for the amazing young man you were, and the one you were destined to be. We hope you know how loved you are our boy, rest well and keep the table warm for us up there.'Cherish was the apple of Ethan's eye, everyone could see how smitten they both were. She was beautiful, elegant, and made Ethan happy. We know you will keep each other young and safe.'Look after each other. Rest in peace.'The petition is available here.
