Lyndsey Anna McCullough, 28, died at a friend's house in West Cross, Swansea, after visiting to socialise in the early hours of the morning. An inquest at Swansea's Guildhall on Wednesday heard she went to the property on Green Bank Road with another friend at 1.30am on July 26.
Events leading to the death
The hearing was told that Miss McCullough, of White Grove in West Cross, was intoxicated at the time of her visit. Whilst at the property, she continued to drink alcohol and had one drag of a cannabis joint. The group of friends sat together on the sofa in the living room, where Miss McCullough fell asleep.
Around 45 minutes later, friends noticed they were unable to rouse her. They moved her to the floor, and one friend, who knew she had been taking medication, believed it may be an issue surrounding that and taking it with alcohol.
Attempts to save her
The inquest heard they decided to try and find Narcan, a life-saving medication used to rapidly reverse a known or suspected overdose, restoring normal breathing and consciousness. When the medication was located at 4.52am, they found instructions to call 999, which they did. At that point, Miss McCullough's breathing had become worse and her lips were becoming blue.
Her friends dialled 999, and the ambulance service advised them to start CPR and to locate a defibrillator, which they did. After five minutes of using the device, paramedics arrived, but Miss McCullough could not be saved and was pronounced dead at 6.05am.
Investigation and inquest adjourned
Police arrived at the scene whilst CPR was being conducted and noted that there were no visible injuries to Miss McCullough. The inquest opening heard her death is not being treated as suspicious. Officers found drugs present at the scene which were seized and exhibited.
A postmortem examination was carried out on July 28 at Morriston Hospital, where a toxicology analysis was undertaken. Miss McCullough's cause of death was proposed as poisoning and a combination of alcohol, heroin, diazepam, pregabalin and sertraline.
Senior coroner for Swansea Aled Gruffydd has adjourned the inquest until February 9 next year for a final hearing. He extended his condolences to the family.
