A bubbly young nurse may have had a hidden heart problem which became fatal when she drank too much at a party before collapsing and dying in her boyfriend's arms.
An inquest heard friends and relatives of tragic 27-year-old Luci Young were shocked when she suddenly leaned forward and keeled over at a birthday bash.
Luci's partner of six years noticed she was slurring her words and suspected she was drunk.
The coroner heard that while enjoying the festivities on July 12 this year, the nurse slumped forward in her chair and began "snorting" before her friends realised she was unresponsive.
Partygoers began to panic and called 999. Paramedics arrived within 13 minutes and attempted to resuscitate Luci.
Surrey Police received a call from the South East Coast Ambulance Service (SECAM) after the young woman, from West Molesey, Surrey, had suffered a cardiac arrest and upon arrival officers described the scene as "chaotic."
Luci was declared dead at the scene in Cobham, Surrey, in front of her devastated partner Tade Akinbiyi, friends and family.
Her mum Toni said in a statement: "Luci was born prematurely at 32 weeks and she excelled in life. She liked to solve problems and was very good at studying.
"I was very proud of her and will miss her greatly."
Mr Akinbiyi organised a balloon send off for Luci and raised more than £5,000 on JustGiving for her funeral and headstone.
He wrote: "Luci was truly a special person and the most beautiful soul. Luci's love spread far and wide and that was plain to see on the day.
"I miss you so much it is beyond belief, the road ahead will be hard but I know there will be a day I will see you again.
"But until then I will lead my life the way you would have wanted with lessons you have taught me. I owe it all to you sweetheart, you have shaped me into the man I have become. I love you always and forever."
Sitting at Woking Coroner's Court, assistant Surrey coroner Dr Karen Henderson confirmed that her death was as a result of cardiac arrhythmia and was alcohol-related.
Among the tributes, Luci's aunt Helen Young said: "What can I say, I feel like I have been torn apart yet again.
"To lose a brother is bad enough, but to lose his only daughter is torture. Why was our Luci taken from us too? A beautiful, intelligent, caring and loving person taken at such a young age.
"Life is so cruel. God bless you my darling niece. My love and kisses always.
"And David, you look after your little girl now. Keep her safe and warm and cuddle her forever in your arms."
