In January this year, Alex Ross-King attended the FOMO Festival in Sydney's west and died after taking three ecstasy tablets.

She was only 19. Her death is one of six recent drug-related deaths at musical festivals - all of them now the subject of an inquiry overseen by the New South Wales Deputy Coroner Harriet Grahame.

The coroner may make recommendations to try to avoid future deaths. On the weekend, she was at the Splendour in the Grass music festival in northern New South Wales to take a look at one measure that could possibly be introduced - pill testing.

Somebody else at the festival looking for answers was Alex Ross-King's mother Jen.

Reporter Michael Atkin and producer Amy Donaldson went to Splendour too for a first-hand look.
