The 15-year-old died on this day in 1984, in Longford.
Ann Lovett is being remembered as a bubbly, fearless and confident girl on the 40th anniversary of her death.
The 15-year-old was discovered in a grotto in Granard, Longford, with her still-born baby lying next to her, on this day in 1984.
She later died in Mullingar Hospital, due to shock caused by haemorrhage and exposure.
Gardaí say her death was fully investigated and the DPP directed no prosecution be taken.

In a statement, Gardaí say the investigation remains open and they continue to appeal for anyone with information to come forward.
