Gardai say they are appealing to anyone with direct information on the death of Kelly Lynch to contact them.
It follows the confirmation yesterday on Northern Sound by her mother Julieanne that she has received important information in recent weeks.
She said the problem was that these people are fearful in Monaghan to go to the Gardai.
An Garda Síochána say the investigation into the death of Ms. Lynch remains open and continues to be carried out by an investigation team based at Monaghan Garda Station.
Kelly Lynch was discovered in the Ulster Canal in Monaghan town on St Patrick's Day 2024.
Gardaí believe she wandered off alone and fell from a bridge into the canal and are not treating her death as suspicious.
Kelly who was from Lisnaskea, was found with 93 different injuries to her body according to an independent forensic report, and her family have repeatedly pushed for a murder investigation into her death.
A new report concludes that it remains the state pathologist's opinion that Kelly's death was due to "drowning" and that there was "no evidence to suggest a physical assault" but her family are continuing to suspect foul play.
Julieanne says there is important information out there that needs to be shared with Gardai.
