Reports attributed to Gardaí, the Republic of Ireland police, said Valdez was murdered, probably by strangulation shortly after being abducted while walking by the roadside in Wicklow county, some 60 kilometers south of the capital Dublin.
The Department of Foreign Affairs (DFA) on Tuesday, May 22, confirmed the death of Jastine Vadez, a 24-year-old Filipina student in Ireland who was earlier reported kidnapped.
RTÉ report that the young woman's body was discovered in Rathmichael, in south Dublin on Monday afternoon.
The suspected killer, Mark Hennessy, was later shot dead by a garda in Cherrywood Business Park on Sunday night.
The scene where her body was found remains sealed off for a third day as gardaí continue to search for evidence.
Ms Valdez, an accountancy student originally from the Philippines, was last seen being bundled into a Nissan Qashqai SUV (reg 171 D 20419) thought to be driven by Hennessy near her home in the village of Enniskerry on Saturday evening.
In an RTÉ report this afternoon, crime correspondent Paul Reynolds said that the note found in the Qashqai vehicle at the centre of the investigation contained the words "Puck's Castle" and "Sorry".
Gardaí have revealed the content of a note left by the suspect in the disappearance of Jastine Valdez. It is believed she died within 45 minutes of her abduction.
Ms Valdez went missing from Enniskerry, Co Wicklow, on Saturday afternoon after reports that she had been forced into a auto.
A GoFundMe account set up for the family of murdered student Jastine Valdez has raised nearly €97,000 from an initial target of €10,000.
A book of condolence was also opened.
