Hundreds of people gathered together at the Diamond in Clones to remember 23-year-old school teacher Ashling Murphy who was murdered while she jogged along the banks of the canal in Tulamore on Wednesday.
The organiser of the local vigil for Ashling, Kathy Dowds, says she had to do something to recognise the tragedy.
Ms Dowds told Northern Sound that she couldn't let Ashling's death go without paying her respects.
Concepta Leonard who was murdered across the border at Maguiresbridge in 2017 was also remembered.
Events are being held across the region, the country and the world over the coming days to remember the Co Offaly teacher.
Meanwhile, Gardai have identified a new suspect in the murder investigation.
They are keeping the individual under surveillance as the investigations into the murder of the 23-year-old continue.
