It came as gardaí held discussions with the Director of Public Prosecutions about charging a man who had been questioned in relation to her death.
The 38-year-old man is due to be charged this morning.
He was arrested shortly after gardaí were alerted to a remote Co Wicklow shed on Tuesday afternoon and found Ms Shortall’s body.
Her brother-in-law, Jon McCabe, yesterday thanked people who had helped in the search for Ms Shortall, who went missing on Good Friday.
Mr McCabe had organised searches for Ms Shortall, née Doyle, who was last seen on Leitrim Place in Wicklow town, at around 4.15pm.

Yesterday, Mr McCabe issued a statement: “On behalf of the Doyle family I would like to thank everyone from the community and the gardaí, the civil defence volunteers, neighbours of Dunbur Glen and friends, Centra Rathnew for the provisions and helpful members of the media for all the assistance, love and support.”
Posting on his Facebook page, he said a vigil would take place last night at 9pm near where Ms Shortall was last seen.
“We are having a candle-lit vigil across the Parnell bridge, near Leitrim Place, to light Anne’s way home... Anyone who wishes to join us is welcome.”
The family had become seriously concerned for her safety overnight on Friday and alerted gardaí on Saturday morning.

Ms Shortall, 47, was originally from Woodside in Rathnew, but had been living in Wicklow town.
A search began at lunchtime on Monday and areas covered included the seafront, the Murrough and surroundings.
Further searches began just before 9am on Tuesday, but were later called off after gardaí discovered her body.
She was found underneath a tarpaulin inside a work shed on lands at Killoughter, near Ashford.
She had suffered injuries to her head.
A 38-year-old man was arrested soon afterwards and detained under section four of the Criminal Justice Act.
The scene was sealed off pending the arrival of State pathologist Marie Cassidy and a forensic examination.
Following a post mortem at Loughlinstown General Hospital yesterday gardaí launched a murder investigation.
A second crime scene, in Wicklow town, is also being examined.
The suspect is due to appear in court this morning.
Ms Shortall’s funeral will take place tomorrow in Rathnew.
