Jozef Puska, 31, charged with murder of Ashling Murphy
He is Jozef Puska, 31, with an address in Lynally Grove, Tullamore.
Mr Puska was heckled as he was taken from a Garda car to a special sitting of Tullamore District Court on Wednesday evening.
The 23-year-old teacher was attacked while exercising beside a canal in Tullamore, County Offaly, just before 16:00 local time last Wednesday.
In court, a detective sergeant gave evidence of the arrest, charge and caution.
The court heard that when the charge was put to the defendant, he replied “no”.
Meanwhile, a second man, arrested under the provisions of Section 30 Offences Against the State Act 1939, has been released without charge.
On Tuesday, large crowds gathered in the village of Mountbolus and outside St Brigid’s Church, where her funeral was held.
Mourners included Irish president Michael D Higgins and Irish premier Micheal Martin.
Vigils have been held across Ireland and the world to remember Ms Murphy and to call for a change in tackling gender-based violence.
Micheal Martin, the Irish prime minister, attended along with Michael D Higgins, the Irish president.
Mr Martin said he wants a zero-tolerance approach to violence against women.
He said a “sea change in culture and attitude in society” was needed.
“We all know there is no single solution to ending domestic, sexual and gender-based violence. Tackling it requires a multifaceted approach with genuine engagement and partnership.
“We need sufficient supports and services available throughout the country, appropriate legislation, an effective policing response and the culture shift within our society that I referenced earlier.
“I can assure you that this Government is working to achieve these goals, and our focus is fixed.”
Campaigners have said that the Irish government does not have a minister with responsibility for gender-based and domestic violence.
Mary McDermott, chief executive officer at Safe Ireland, which campaigns for women and children’s safety, said the government’s approach to the matter was “fragmented and scattered”.
