And it has now emerged gardai have unearthed new evidence in their search for Ashling's murderer.
Here's a timeline of events in the shocking case.
Wednesday, January 12 - Ashling attacked and murdered
Ashling is attacked and murdered in a horrifying act of violence as she jogs along the banks of the Royal Canal in Tullamore, Co Offaly. Shortly after a man is arrested in connection with her murder.
Gardai issue an appeal for information on a distinctive mountain bike as part of their investigation into the murder. Investigators ask anyone with information regarding a black Falcon Storm mountain bike with straight handlebars and distinctive yellow/green front forks to come forward.
Thursday evening - the country mourns
Heartbreaking candlelit vigils take place across the country for popular Ashling. Thousands gather in Offaly, Dublin and other parts of the country to mourn her shocking death.
Thursday night - man released
The man being held over Ashling's death is released and 'eliminated from Garda inquiries' and deemed 'no longer a suspect'. Donal Farrelly, who represented the man during his two days of questioning, condemned those who had tried to identify him on social media.
Mr Farrelly told the PA news agency: “This man has been vilified on social media and clearly identified on social media.”
The solicitor said his client had endured a “traumatic period” while at Tullamore Garda Station.
“Any form of interrogation or questioning is inherently traumatic,” Mr Farrelly said.
Friday evening - poignant family moment in Tullamore
Ashling's heartbroken family and other mourners hold a ceremony along the banks of the canal in her memory. Her father Ray plays the banjo as When You Were Sweet Sixteen was sung by members of Best Foot Forward and locals.
Ray along with mum Kathleen, sister Amy and brother Cathal along with wider family members, arrived and walked the opposite side of the canal to where Ashling was violently assaulted and died on Wednesday evening. They then made their way back to the large crowd where people held candles in her memory and a minute silence in her memory was observed.
Fr Declan Thompson of Daingean parish said: "An evil form of violence took away a life that leaves all of us stunned with all sorts of feelings.
"We're sad that a young life was taken needlessly.
"We're sad that once again violence seemed to win out. And because of that sadness, we feel helpless. We feel hopeless. We don't know what to do."
Friday night - Taoiseach pays tribute
Taoiseach Michael Martin attends a vigil and lights a candle for Ashling.
Speaking at the memorial event he says that Irish men must take “a lead role” in changing the culture of violence against women in society.
The Taoiseach also says Ashling, who was a talented fiddle player, personified the very best traits of a "traditional Irish national school teacher".
Saturday - new details emerge
New details emerging from the case suggest brave Ashling fought for her life and left Garda detectives crucial forensic evidence that may help nail her killer.
The Star has confirmed that gardai have the killer’s DNA after the heroic teacher fought him during the brutal attack.
Gardai say they have made significant progress and sources believe they are close to making a breakthrough in the coming days.
Although there has been no fresh arrest in the massive murder investigation, sources have confirmed a suspect has been identified.
The man handed himself in to a hospital in the east of the country — some distance from where Durrow National School first class teacher Ashling was murdered as she jogged on the banks of the Grand Canal on Thursday evening — more than 24 hours after the killing.
It’s understood he had cuts and bruises and gardai who were alerted to that initially believed he may have been involved in an incident in the city.
But gardai then became suspicious his injuries may have been related to Ashling’s murder and officers from Tullamore investigation team were sent to the hospital.
Gardai are monitoring the man in case he tries to leave the hospital where he is still receiving medical treatment.
