A teenager tragically died after inhaling laughing gas at a house party. Kayleigh Burns, 16, collapsed moments after being recorded taking the drug - formally known as nitrous oxide.
Ms Burns, originally from Halewood in Merseyside, fell ill during the party in Leamington Spa in Warwickshire on the night of June 4 this year.
Her sister, Clare Baker, 31, said she first received a message from one of Kayleigh's friends to say she was taken to hospital by ambulance. Clare then rang around a number of hospitals in the area trying to find out if her little sister was okay.
